What is a restaurant app?

At first glance, the definition of a restaurant mobile app seems pretty plain and clear — what is there to discuss?

Restaurant apps are mobile solutions that connect restaurants with their customers or suppliers and help store information in one place.

However, there is no gold standard for restaurant mobile app development and each platform can significantly differ from the others. Think about apps you have on your phone: one for online food delivery, one for table reservations, one for leaving ratings and reviews, and all of them can be called “restaurant apps,” because they are utilized by different cafes and restaurants.

Though the definition of a restaurant app is very broad, one thing is clear: these solutions are created for restaurants specifically to help them improve their operational processes. 

Stats and facts about the restaurant app development sector

According to recent research, food-related services remain one of the fastest-growing segments of the billion-dollar app market. Undoubtedly, the pandemic contributed to the rapid increase in audience, revenue, and investing interests. Here we’ve gathered some important facts and statistics about restaurant mobile app development.

• • The food delivery app industry is projected to grow to a market size of $165 billion by 2029.
  • Meal kit delivery services are anticipated to reach $19.52 billion by 2028, setting a new record.
  • American customers prefer using restaurant applications over third-party platforms primarily for convenience (27%), ease of use (22%), and lower fees (22%). Additional benefits include lower costs and faster service.
  • Key features valued by restaurant guests while online food ordering include loyalty programs, online reservations without phone calls, and the ability to order food via mobile or web platforms.

Statistics show that the food-tech sector is growing rapidly and is expected to expand dramatically in the upcoming years, alongside increasing investors’ attention. The restaurant mobile app development service is in huge demand now, and if you have an idea in the field, it is a good time to start acting.

Trends in restaurant app development

Over the last few years during the pandemic, restaurants realized the importance of online order processing. There are a few trends that will make your restaurant app take off.

Cashless payment. This trend has become popular during the pandemic. It is faster and more convenient to make an order and pay for it right there, in the app. 

Menu filtering option. Clients get more selective about the kind of food and a system of filters is essential. It helps users of a restaurant app find those dishes that they could have missed without filters.

Loyalty programs. Creating loyalty programs makes your app more popular and customer-oriented. They work well, as they encourage customers to place orders in the same restaurant again and again to get purchase rewards and bonuses. Over time, these users can turn into loyal customers.

Most common types of restaurant applications

Before jumping to restaurant mobile app development, let’s discuss what types of solutions exist out there and what business purposes they serve. Generally speaking, there are several ways to categorize restaurant mobile apps, based on who uses the platform and why. In this chapter, we will break down the most popular categories, and in the next one discuss successful examples. Let’s dive in!

Restaurant-supplier vs. restaurant-customer apps

One way to categorize food apps is based on who is on the receiving end: the vendor or the customer. This will influence the app development process and user flow.

👩🏻‍🍳➡️🥦 Restaurant-supplier platforms connect owners with vendors. Through these apps food spots can move all interactions with their suppliers online. Also, some platforms allow users to browse a catalog of fresh produce and beverages and compare prices. 

If you are not into the restaurant business and app development, you probably have not heard of examples for restaurant-supplier platforms. But you can always look them up. They include Kitchify, Choco, or Grecha.pro. 

👩🏻‍🍳➡️🙋🏻‍♂️ Restaurant-customer platforms place regular clients on the receiving end, while the main goal of the solution is to connect food places with its customers and make this interaction smooth and quick for both ends. They can serve several purposes, for example, help clients order food online, get it delivered, leave reviews, book tables and find hot spots in new cities.

The restaurant-customer segment is very dense and has several subcategories, depending on the main activity users can perform on the app.

Reviews platforms that allow customers to share their experience about restaurants and dishes they tried there. Prominent examples of mobile app development of this subcategory are Yelp or Urbanspoon.

Online order and delivery apps are the most popular subcategory, as it helps customers place orders for takeout and get their favorite meals delivered to the doorstep. Examples are well-known to anyone across the world and do not need a long introduction: UberEats, Wolt, Pizza Hut, or even McDonald’s.

Reservation apps help busy customers to reserve a table without calling a restaurant. For this purpose, one can use OpenTable or NewTable.

Restaurant locator apps assist users in finding nice restaurants nearby. Usually, they include features from other subcategories, for example, ranking and reviews, so customers can read about other people’s experiences and choose where to go for brunch or dinner. One of the most popular examples of restaurant finder platforms is Zomato.

Loyalty program apps enhance the stewardship between a restaurant and its customers. When using these platforms, clients can get points for their purchases and exchange them for different rewards: discounts, free meals, or drinks. For example, with the Starbucks Rewards app customers of the coffee shop chain earn Stars with every drink they buy and redeem them later, which keeps them coming back to the company.

Single vs. multi-restaurant applications

Another way to approach restaurant mobile app development is to decide how many restaurants will use the solution. 

👩🏻‍🍳 Single-restaurant apps serve only one particular business. Usually, it allows customers to check the restaurant menu and order takeout or delivery. As you can guess, it is expensive to own a restaurant app, that is why only big global corporations, like Taco Bell, KFC, or McDonald’s can afford custom restaurant app development. Small local companies and early-stage businesses prefer to utilize third-party services to cut operational costs.

👩🏻‍🍳 👩🏻‍🍳 👩🏻‍🍳 Multi-restaurant apps serve as a “middleman” and connect multiple food places with customers, delivery drivers, or vendors. This type of app development has a lot of potential, as the more restaurants join the platform, the faster it grows. A perfect example of such a solution is any food delivery app, such as Wolt, GrubHub, Bolt Food, and others.

8 restaurant app examples 

To better understand the theory, let’s move on to the practice and discuss real-world examples of these applications. We picked 8 creative and robust solutions that you need to learn about before approaching restaurant app development.

Restaurant-supplier apps

Choco is a free-of-charge platform for restaurant businesses to connect with the suppliers and keep all kitchen orders in one place. It was founded in Berlin, Germany, in 2018, and in 2020 it raised $30.2 million in funding. Currently, the company is valued at more than $250 million.

The platform provides chatting functionality, a contact book, a catalog of vendors, and a tab to track current and past orders. A chef or a restaurant manager from any city and country can sign up, provide the details of their restaurant and browse the catalog. As soon as they see something they like, they can place a kitchen order and keep an eye on it.

Moreover, the app targets not only the restaurants but also the suppliers — through the platform, they can find new clients. Often sales reps simply do not have time to knock on every small restaurant door and offer their services and discounts in person. With Choco, they can do it digitally and reach even more food spots while saving time and money. For example, one of the platform’s first clients, the vegetable suppliers in New York, had over $800k of produce to sell when the pandemic hit. It had to be done quickly before all the food went bad. They joined the app, found customers, and now have more than 500 orders a day, thanks to Choco.

Grecha.pro is software that helps restaurants automate and digitalize their orders. So far it works only on the Russian market but has plans to expand in the future. The flow is very clear and intuitive: a restaurant manager signs up, chooses the best offer, opens a chat with a supplier, and places an order — all in 3 clicks.

The hallmark of Grecha.pro is an integration with the messenger Telegram and e-mail. Why is it cool? Because at this stage restaurants can use Grecha.pro messenger to chat and place the orders, while suppliers don’t have to download anything. They can just stay in an app that they already use: Telegram or e-mail. Moreover, the app allows you to add other employees to the chat, so they can also keep track of the order and control the process. 

💡If you want to know how we created Grecha.pro, came up with UI/UX design and why there is a buckwheat cereal on the logo, read our design case about the app.

Restaurant-customer apps

Open Table is a multi-purpose app that combines several key features. It allows users to reserve tables online, read and leave reviews for dine-in seating, and, at the same time, earn rewards towards free meals and drinks. 

The platform is a veteran of a digital world — it was founded in 1998 and initially covered only the San Francisco area. The founder, Chuck Templeton, struggled to make a restaurant reservation over the phone. In 2014 the company was purchased by Booking Holdings, which also owns Booking.com and Kayak, for $2.6 billion.

NoTab is a platform for nightclubs to take automated orders and mobile cashless payments. The flow of the app is very simple: a customer can book a table in the app, then, when they arrive, scan a QR code, check the menu, and order food and drinks. Same for the dancers. This platform even automatically checks that guests are not underage if they want to order alcohol.

When guests are done with the meals, they can see the bill, pay it, and tip the waiter. Meanwhile, the restaurants can see generated reports about customers’ habits and behavior to make better business decisions.

However, the architecture of NoTab is not that simple. In fact, it is 5 apps in one: for a guest, for a waiter, for the kitchen, for dancers, and one more for a manager to supervise the process. The Purrweb’s team developed all 5 applications concurrently, within only 6 months.

Single-restaurant app

KFC is an app that belongs to the global fast-food chain Kentucky Fried Chicken (KFC). As we mentioned before, custom restaurant software development for only one restaurant is usually on the expensive side and is difficult to scale, because it is limited to a particular chain. 

With the KFC app, a user can find the nearest restaurant, check the prices, order online to skip the line, and schedule the takeout ahead. Also, to attract more customers to the platform, the app promises special offers and personal discounts for app users only. The app works in many regions and is adapted for local languages. In some countries, users can also order delivery.

The same model is used by many other fast-food chains: McDonald’s, Burger King, Taco Bell, Chipotle — all of them have money for these app development services and build a custom, single-restaurant app.

Multiple-restaurant app

DoorDash is the app we all know. Even before you became interested in restaurant app development, you probably had used delivery apps to get meals and drinks from restaurants. Now, this is one of the most popular food ordering platforms with a market share of 57% in the United States. The brand was founded in the early 2010s by Stanford students who were helping a local sweets shop with the delivery technologies. In 2013 they launched an MVP — PaloAltoDelivery.com, that was mostly popular among fellow students. The company started growing faster than anyone expected. In 2018 DoorDash overtook UberEats, and in spring 2019 they left behind another major competitor — GrubHub.

The main idea of the app is to decrease the number of steps users have to take to order food, which leads to a higher conversion rate. Therefore, the design of the interface is minimalistic and contrasting, yet intuitive to customers.

Key features for restaurant apps

When talking about restaurant mobile app development, it is nearly impossible to skip talking about essential features for a mobile solution. The first step to define the functionality of your future platform is to choose a target audience and a category your app will fall into. If you want to build a restaurant-supplier app, you need one set of features. If you want to build a restaurant-customer app, it will be a completely different choice.

In this chapter, we will cover the necessary features for each type of restaurant app and share some examples of how they can be executed. Let’s go!

Restaurant-supplier apps

The target audience of these mobile apps consists of restaurant managers, owners, chefs, and vendors. In order to successfully complete a supply order, users will need 5 main features: a welcome page with the signup and login forms, a customer profile page, a catalog, chats, and a tab with order history. 

The signup and login page

This is the first thing a user sees when they open the app. We can compare it with opening the first page of a book — if the font is too small, the paper is thin and yellow, and the exposition is boring, you probably would not buy it. Same with a mobile app. The welcome page should be clear and straightforward, while signup and login forms need to be short and ask for necessary information only. See how other restaurant app development teams have done it:

The user profile

A profile is a page where customers can provide their personal information, including a phone number, address for deliveries, and comments for a driver on how to find the location. Suppliers also need to list products they have to offer and prices.

Contact book or a catalog

After a restaurant manager or a supplier sets up their profile, the next step is to see the offers. Usually, restaurants have a big catalog of vendors’ profiles to browse and a contact book or a favorites list to save who they like. For the app development process, the necessary elements for this page would be a search bar, if a user wants to find a specific supplier or contact a particular restaurant, but also filters, for example, location, delivery time, produce available, and other categories to narrow down the search.

Messaging functionality

When a restaurant finds a supplier they want to work with, they need to get in contact with them using a messaging feature. Also, for a better flow, restaurant app developers can integrate the option to place and track orders right in the chat. For instance, on Grecha.pro, users can see their order history in the chat and add comments for the supplier about the delivery.

The “Orders” tab

This feature is optional, but very useful, as it keeps everything in order and helps users track their previous and current orders. Also, on these pages, customers should be able to initiate the return process if they are not happy with the quality of the products. Here are some examples of the “Order History” page:

Restaurant-customer apps

The restaurant-customer solutions are not much different when it comes to app development. For these platforms, the target audience are restaurant representatives, delivery drivers, and hungry customers. They require several key features to be considered during the restaurant app development: a welcome page, customer profile, restaurant catalog, menu, in-app payment options, push notifications, and a customer loyalty program.

A welcome page and a user profile

These features serve the same purposes as they do in the restaurant-supplier apps. Here they should also be simple and clear, but there is a small difference. Restaurant-customer apps need more information about the user, including some payment information and exact geolocation. The restaurant and courier’s side of the app also needs a registration form.

Online ordering functionality

For ordinary customers, it includes a restaurant catalog and menu, for couriers—actual order base, while for restaurants it needs to be an administrative panel with current inquiries. At Purrweb, we always consider different user scenarios during the mobile app development stage.

Favorites or saved lists

This feature helps to increase the rate of customer satisfaction. How do these things even relate to each other? Easy! When a user wants to order food from their favorite restaurant, they need to take fewer steps and spend less time. Instead of looking for the spot in the catalog, they can just open the favorites list and instantly see the menu with meals they previously ordered. 

Payment options

Payment options for restaurant-customer apps are a must. While card payments are the most common ones, you can also include Apple Pay, Google Pay, cash, and even cryptocurrency if you want. Talk to the team during the app development process to find out what will suit your targeted audience the best.

Push notifications

In-app notifications are essential to keep every party updated and increase the retention rate by sending reminders and special discounts. That is why it is important to take them into account during the app development stage.

Rewards programs

User rewards can also be optional, but if you want to make people come back to your platform, it is a must for app development. The idea is simple: customers earn points for orders, and later can spend them on free meals, discounts, and other perks. Such loyalty programs help with customer engagement and stimulate users to repeat orders.

Steps of restaurant app development

Now it is the time to discuss what the app development process looks like and what the development team does to create a restaurant app. If you are new to the IT field, this chapter can help you understand how costs and timeframes for a project are calculated at Purrweb.

1. Costs and timelines estimation

To start, we plan the app development process, estimate the app development costs and figure out how much time we will need to build a platform. At this stage we will need as much information about your idea as possible, so we will set up a meeting to ask questions and dive deeper. It is free of charge for our clients — we will only ask you to find some free time for our sales manager. 

What influences the cost of app development for restaurants most? Usually, it’s the functionality of the app and, therefore, its complexity. For example, an MVP doesn’t require as much code to write and time to invest from the team as an app with some advanced features. API integrations (for payments, ordering, etc.) also demand time and employees to do the job. Not to mention server specifications, database size, and all the programming stuff.

Luckily, you can choose the most relevant features to include. So that, the project matches both your business goals and the amount of available resources. That’s why we pay a lot of attention to realistic estimation and especially “hidden rocks”.

After the estimation is completed, we will send you a Google Sheet with a detailed breakdown of the price and timeline. Then you can decide if our vision of time and budget suits you and if you want to move forward.

⚙️Tools: Google Sheets, Zoom.

📝Results of this stage: Estimated price and timeframe based on user stories.

2. UI/UX design

During this step, we go through several stages to create an aesthetic and intuitive design.

The first thing we do is conduct market research. Don’t get confused if we ask you for some references. It really helps to better understand the client’s taste. We also examine the major players in the market, the latest trends, customers’ needs and preferences.

Then we create a mindmap, showing user experience while using your app. At first, it doesn’t look that appealing, as the wireframe is completed in black and white colors. But it’s the chance to build a restaurant app that won’t irritate hungry users with illogical screens and non-obvious features.

After that we create the first mock-ups and work on the visual side — colors, styles, fonts, icons, and position of the design elements. Our designers develop a concept that will help your app to stand out in the market and attract more customers. The design of the app gives people the first impression which really matters in the world of quick decisions. 

When we complete most of the work, it’s time to present the design and discuss it. Once you approve our concept, we finalize all the screens and create a UI-kit for an app. If you have an in-house app development team, our tools and files will be enough to assemble the design of the solution.

If you want to build your app with us, we will review the app development costs again: sometimes, during concept approvals, clients ask for extra features that we did not initially discuss.

⚙️Tools: Figma.

📝Results of this stage: Ready-made and approved design screens and a UI-kit.

3. Choosing a technology stack

Platforms

Decide on which platform you want to build a restaurant app. If for both, Android and iOS, then you need to make a cross-platform mobile app. At Purrweb, we use React Native for this purpose. If you decide to make a native app, then you need to build an app for each platform separately and use two different programming languages. 

Cloud servers

Cloud servers help to store and back up data and keep software running smoothly. If you select the server type for your restaurant application, cloud servers like AWS, Azure or Google will provide continuous connection. You’d better choose it wisely as the scalability of the project also depends on the possibilities of the cloud server. 

Analytics

With a proper analytics API any restaurant owner will appreciate your app more. As it becomes a convenient tool to gain insights into customers preferences, the effectiveness of promotions, and user engagement. This way, restaurant owners increase their revenue and keep using your app. As for some specific examples, analytics API like Google Firebase will provide quick analytical processing of the data.

Customer connections

If we are talking about customer connections, there are several ways to build them. For example, you can provide multiple payment options by using Braintree, Stripe, or PayPal integrations. For location tracking it’s widespread to use Google Places API. You can also provide user registration, in-app chat, and the opportunity to leave and see customer feedback and reviews. All inclusions and specifications are defined on the design stage.

⚙️Tools: Platforms (iOS, Android), cloud servers (AWS, Azure, Google), APIs.

📝Results of this stage: Chosen tech stack.

4. Restaurant app development

Now it is time to create a restaurant app. At Purrweb, we work in two-week sprints, presenting intermediate results after each. Usually, in the meantime, we come up with one or two features for your future solution. After each sprint ends, we can send our clients a report on the process or give access to Jira, a software that we use to track tasks and see what has been completed.

⚙️Tools: React Native, React, Node.js, Electron.

📝Results of this stage: First version of the app.

5. QA testing

When our app development team has finished a feature, it goes to QA engineers who look for any potential bugs. 

Choose a strategy

At Purrweb, we don’t wait until the whole app is ready. Instead, we take 2 days after each sprint to test the solution and solve any problem on the go. This way, the team maintains high quality during the whole process of app development for restaurants. QA engineers catch issues and developers fix them on time.

Define the testing tools

The testing tools are essential for QA engineers as they help to effectively identify bugs. Whether opting for manual or automated testing, it’s essential to pick tools that match the specific needs of the project. For example, if the app includes lots of user interactions (like menu selection, customization, and payment), manual testing is better. 

Write the test cases

Creating test cases involves detailing step-by-step instructions for testing the app’s functionality. These documents serve as a roadmap for QA engineers, making it easier to define and address any problems. Take even such a basic feature as user registration. This case must include two scenarios with valid and invalid user registration data, and that’s just the beginning.

Execute the test cases

This part of the process helps us find mistakes, things that don’t fit right, or any issues with how the app works. When we spot these problems early, we can fix them right away. This keeps the app strong and trustworthy, making it work well for users without a bunch of errors piling up.

⚙️Tools: Vercel, Postman.

📝Results of this stage: App development is done.

6. Mobile app launch

Finally, we’ve made it to the mobile app launch. Now it’s time to create a developer account on AppStore or Play Store (or both). Then you should submit your app to the app stores for review. It may take a few days to a few weeks for approval. Don’t forget to place some marketing materials like screenshots, promotional videos, and a compelling app icon. Keep an eye on user feedback, reviews, and app performance. Be prepared to address any issues quickly.

⚙️Tools: AppStore, Play Store.

📝Results of this stage: A successfully launched app.

7. Post-launch support

When your app is released on the App Store or Google Play, our job is not done. First of all, marketplaces often update the requirements, and the app needs to be enhanced as well in order to comply with all the rules. Secondly, when the solution faces real-world customers, clients can realize they need to add extra features or scale the solution up to other markets and regions. Here, Purrweb always comes to help.

📝Results of this stage: Polished, up-to-date app.

Factors to consider when developing a restaurant app

Competitors analysis

Research and define what exactly attracts visitors to your restaurant. The modern market is filled with various restaurants and the challenge is to be different from competitors and more convenient for clients. Creating an app that highlights attractive offers would be the right decision if you want customers to download and use your app.

Simplicity of a well-working app

There is no sense in creating an app that’s hard to understand. The app’s logic should be simple. Nobody wants to deal with complicated interfaces, especially when the users are hungry. If clients can’t place an order in a few clicks in your app then they most likely will leave.

Budget

How much are you going to spend on app development? You should think about the profit you want to get from the app and recover the app development cost. If your initial requirements are overshot then you need to make a plan to balance your expectations.

Challenges to keep in mind before restaurant application development

Creating a custom app involves dozens of possible challenges. Keep them in mind and seek strategies how to overcome problems before development starts. 

Here are three main challenges companies often face:

Risk of a high churn rate in restaurant industry apps

Most people don’t use restaurant applications regularly, which increases the churn rate. This metric indicates that you are losing old users. It also suggests that attracting new customers to your app will be worthless in the long run, as people quickly stop using the application.

To lower the churn rate, every aspect of your app should provide a seamless user experience to stimulate future repeat purchases. Also, reflect on creating personalized notifications and offering special deals to prevent users from forgetting your app.

Need to integrate restaurant systems with the app

Food apps need to be connected with inner restaurant systems, which can be done through integrations. For example, a delivery app needs POS, inventory management, and kitchen display integrations. Real-time order statuses and menu changes require a lot of effort with extensive backend infrastructure and reliable data synchronization. These features can also be rather costly.

Competition with big sharks on the market

People prefer using apps that are mainstays of the market, over solutions that have just appeared. To gain a sizable market share, you should scrutinize the strengths and flaws of your biggest competitors. 

Your app should have all the features your customers might expect from a modern restaurant application. If everyone has convenient features like real-time order tracking or table reservation, and you don’t, why should people choose you?

A professional development agency can help you integrate all the necessary features in the app, and withstand the competition without exceeding your budget.

Timeline and costs of app development 

Now, after we’ve discussed the main steps of the restaurant app development process, you can better understand how costs and time frames are calculated. We asked our team to put together an estimation for a restaurant app MVP, you can find it below:

Stage	What are we doing	Estimation in hours	Estimation in weeks	Approximate costs
Project estimation	We discuss an idea of your app and estimate the costs and timeframes for the app development	20 hours	—	no costs
UI/UX design	Map users’ journey, come up with design concepts for each step, and present them to you	124 hours	4 weeks	$4960
App development stage	Work on architecture and the interface on both client and server-side	882 hours	10 weeks	$35,280
QA Testing	Look for any possible bug and fix it before it even occurs	250 hours	concurrently with the development	$4500
Project management	Manage the mobile app development project and solve administrative tasks	—	4 weeks for the design stage 10 weeks for the development stage	$400 $2500

Overall, if you have an idea for a restaurant platform, app development services will cost you $47,640 and will take approximately 1276 working hours, which equals 3,5 months.

Wrapping up

Let’s reinforce the key points of the article:

• • Restaurant applications are mobile solutions that connect restaurants with their customers or suppliers and help store information in one place. 
  • The food industry is growing fast. Stats show that in 5 years, the food delivery app industry will grow to a market size of $165 billion.
  • There are several types of restaurant apps, depending on who uses them and how many restaurants are connected. Before you start mobile app development, you need to define your idea’s category.
  • The most common types of restaurant apps are restaurant-supplier and restaurant-customer solutions.
  • Key functionality also depends on the type of your restaurant app. Discuss the details with your app development team.
  • Approximately, the restaurant app will cost you $47,640 and will take 3,5 months to build.

To sum up, restaurant app development can be complicated if you do not know what type of app you need, who your target audience is, and what features to pick. To nail mobile app development and create a successful, robust, and reliable solution, it is always a good idea to hire professionals.
