Is it a good idea to build a messaging app?
Messaging apps have changed the way we communicate. They have given us the ability to instantly message our friends, family, and colleagues and always stay in touch. The popularity of services like WhatsApp, Facebook Messenger, and Telegram has inspired many entrepreneurs to think about developing their own messaging apps.
Let’s take a look at some statistics:
- Statista’s data also shows that the most popular messengers in 2024 are WhatsApp, WeChat, and Facebook Messenger. The latter two apps have more than 1 billion users, and WhatsApp has over 2 billion. This shows just how big the potential user base is.
- According to Statista, the number of messenger users is expected to increase from 4.24 billion to 7 billion by 2030. This shows the popularity of these applications, and the market for them is still very much growing.
The numbers prove how important messengers are in our daily lives
The size of the market and the number of competitors may intimidate you. But if you thoroughly study the market, you can try to find your niche and develop unique features that will help you stand out and make your chat app a success.
How to define the key features
There is a set of functions you need to consider in order to create an instant messaging app. At Purrweb, we believe an app should be user-friendly in the first place and consider customer pain points.
Therefore, we always advise you to start with brainstorming and defining your niche, unique characteristics, and target audience. Then, you can move on to execution and pick the functionality you need for your app. You can find more tips on selecting MVP features in the article below.
Must-have features
Based on our experience, we created a list of must-have features for the best messaging app.
Authorization
The registration process should be fast, and to make it fast, we recommend adding the ability to log in via social media, phone number, or e-mail. After this, the user will be able to choose a photo and a username. Some apps like Telegram allow users to create multiple profiles. It might be beneficial, for example, if you live between two countries and have multiple SIM cards.
Access to contacts
This feature makes the onboarding process in an app like WhatsApp much easier because a user can sign up, sync contacts, and instantly start messaging.
Messaging
The instant messaging feature is the core of your chat app. Your app will need elements like private and group chats, send and unsend messages, delivery status, text history, and editing functionality.
File exchange
The ability to exchange media files can extend the variety of reasons why people will use your instant messaging app. Let users send photos, videos, GIFs, and documents to each other and use chats as cloud storage.
Push notifications
Users should instantly be notified that they have received a new message. If you have ever used a chat application in your life, you probably know how important notifications are 😉
Data protection
When it comes to any kind of communication, personal or work — privacy is important. Users’ data is usually stored on app-owned servers, and messages are encrypted and transferred between devices using different communication protocols. Consult us to learn more about data security technologies and create a safety messaging app.
Geolocation
It can be integrated into your chat app messenger with the help of third-party services. Geolocation allows users to share their position with others. The messenger also uses geolocation to set the language of users’ current place of residence.
Nice-to-have features
These features are not required from the start, as they can ramp up the cost of building a chat app. But they definitely enhance the instant messaging app experience, so note them for the future.
Video and voice calls
Consider adding voice and video calls. Maybe it’s not that necessary in the first app development stage, but as soon as you have resources, it’s good to consider expanding the functionality to the call exchange.
When you implement voice and/or video calls, make sure that they are properly protected. With end-to-end encryption (E2EE) in place, no third party will be able to intercept information traveling between the devices of call participants. And even if they do gain unauthorized access to the data flow, it will be impossible to decrypt.
Chatbots
This feature will attract businesses to your chat application. Chatbot is automatic software that maintains online communications with customers, sends automatic replies, and answers frequently asked questions. They can also call a human if a user’s question is too difficult for the machine.
Channels
First launched by Telegram back in 2015, channels are a form of one-way communication platforms similar to communities in social media. They allow users to directly reach their subscribers with any type of content, be it text, video, or audio. The current staple in the industry are Telegram channels, which support an unlimited number of subscribers, feature multiple analytics tools for admins, and offer content protection measures. For example, the channel owner can block screenshots or disable message forwarding.
Self-destructing messages
Self-destructing or ephemeral messages are a simple and effective privacy protection tool. Once the recipient reads the message, the app permanently erases it from every chat server. Perfect for discussing legal matters, receiving medical consultations, or sharing sensitive corporate info.
Looks massive? Here’s a compact list of the key features for you to take a look at.
| Must-have messenger features | Nice-to-have messenger features |
| Authorization | Calls |
| Access to contacts | Chatbots |
| Messaging | Channels |
| File exchange | Disappearing messages |
| Push notification | |
| Data protection | |
| Geolocation |
Technology stack for a messaging app
There are several aspects of building a messaging app like WhatsApp. First, you need to consider which communication protocol to use. It regulates how devices exchange information with servers.
Three protocols can be used in instant messaging app development:
-
- Extensible Messaging Presence Protocol (XMPP) — an old protocol made for real-time messaging that is easily adaptable to different needs.
- Message Queuing Telemetry Transport (MQTT) — popular in IoT (Internet of Things) devices, comes with minimal features only.
- WebSockets — a newer protocol that allows the user-server exchange even without requests from the user’s side.
To create a messaging application, you’ll need to choose between native and cross-platform app development. Native app development essentially means building different apps for each operating system. To build a chat app for iOS natively, you’ll need developers experienced in Objective-C or Swift. For native Android apps, the tech stack will be Java and Kotlin.
And if you want to make a messaging app suitable for both systems, opt for cross-platform development. Then, the tech stack for both iOS and Android app development will be the same.
Before we move on to the app development costs, here’s a bonus tip from us.
Save your time and money by choosing React Native
When entering the market with your first-ever chat app, choose to develop it with React Native. It is a UI software framework created by Meta in 2015. It works with JavaScript — one of the most popular programming languages across the world, so it’s not difficult and time-consuming to find a contractor for your messaging app development.
Why choose React Native?
There are 4 major benefits of working with a team that develops on React Native.
-
- Cross-platform development cuts the time for messaging app development, reduces costs, and enables developers to deliver a unified user experience across multiple platforms using just a single codebase. And there is no need to hire and pay two separate teams for software development.
- React Native has massive libraries of native UI elements for building interfaces. This simply means that your future app will scroll, swipe, and tap like native-build ones. And it matches what users expect. The performance of the chat app will be native, but you’ll save tons of time and money choosing React Native over the native chat app development.
- React Native is a JavaScript-based framework. It allows developers to use the same language for both client-side and server-side development, simplifying the workflow.
- React Native allows for simple integration of third-party services. Using them is a way to reduce the costs of chat app development. If you have a tight budget, implement certain features with ready-made solutions. Examples include payment gateways, chatbots, ad managers, social media embeds, etc.
We have been working with React Native for the past five years. The framework allows us to create MVPs for our clients in three months — you will have a working chat app that you can test to collect user feedback and show to potential investors.
With React Native, you can develop an app simultaneously for both Android and iOS
Step-by-step guide: how to create a messaging app from scratch
Creating a messaging app requires experience, knowledge, and time. There are some steps to follow:
Pick the most crucial features and estimate the scope of work
In the first stage, you need to estimate the functionality of your project. When you approve all the necessary chat app features, a business analyst forecasts the scope of work. If you’d like to follow the MVP approach, we recommend focusing only on the most crucial features.
Design the messaging app’s UI/UX and make a UI kit
Designers collect references, which helps to grasp the client’s taste. Then, they draft the instant messaging app architecture — a mindmap that shows all the logic of the app and wireframes that show the position of buttons or content. Then, designers create a concept — a ready-made part of the app that shows a particular flow. When the client approves the screens, designers make mockups and UI kits.
Develop the front/backend and implement all the necessary features
Specialists put the app development process in motion — it’s a task for backend and frontend developers who will build a fully working product and all the app functionality. The process is complex, but here are some of the steps our developers follow to create a chat app. To build a messaging app, we:
-
- Create a directory and install the required dependencies.
- Develop a channel list to display a list of available chat channels or group chats.
- Develop a message list to display the conversation history within a channel or group.
- Develop a message input feature that allows users to compose and send messages.
- Implement a user authentication system.
- Implement a file-sharing feature, push notifications, audio and video calls, and geolocation.
- Add other chat functionality you want to include in the app.
We develop apps using two-week sprints, and at the end of every sprint, we are ready to show one or two finished features.
Check your messaging app’s functionality and security
QA specialists test your instant messaging app and check its efficiency, safety, and functionality. If you develop a cross-platform app, they will test it on both iOS and Android. At the end of each sprint, we allocate two days for bug fixing. Every two sprints, we do regression testing because we need to be sure that all features work together correctly.
Launch and market your messaging app
When the app has been released, it doesn’t mean that the task is completed. Often, the released app needs maintenance, and in most cases, the app development agency supports the app after the launch.
Let’s discuss the messenger development price.
The roadmap we use at Purrweb
Possible obstacles when building a chat app
Developing a chat app may not seem like a difficult process. However, before you start developing, take some challenges into account that can affect the performance and success of the application. Here are seven of the biggest ones.
Oversaturated market
It’s not enough to just create a chat application, you also need to somehow attract users. Identifying unique features that your competitors don’t have can help. It can be challenging to come up with something new because there are already hundreds of applications on the market. On top of that, messaging apps tend to have a pretty standard set of features.
Think about what will convince people to download your chat app. One way to do that is to look at what’s gaining popularity and be one of the first to implement it. Or you can focus on niche features that meet specific market needs.
Security concerns
App users want their conversations to remain private and secure. You can achieve this with end-to-end encryption. Encryption uses cryptographic keys stored on the endpoint devices to encrypt messages when they are sent out and decrypt them when they are read. This means that only the sender’s and recipient’s devices can have access to the messages.
During development, the team should think about other potential vulnerabilities, such as phishing or data leakage. They need to implement additional authentication and encryption methods.
Server overload
It’s one thing to have a hundred people using your chat app, and it’s different to have millions of them. With a rapid growth in popularity, server overload can become a serious problem. It can lead to slow message delivery and app crashes. It would help if you thought about scalability in advance so that your servers can handle the high load.
Consider horizontal scaling so that the application can allocate resources to handle the growing traffic. This method increases the capacity of a system by adding more servers to the existing ones. For example, Facebook and Google use horizontal scaling to cope with high user traffic during peak periods.
You can quickly adapt to server load by increasing or decreasing the number of machines
Data storage
Another problem that can arise due to the large number of app users is a lack of storage. Since people can send large amounts of files, you need to think about optimizing data storage. To avoid overloading servers, the best solution is to use cloud storage. It offers cost-effective, secure, and scalable data management.
The cloud has another advantage. In case of device loss or other unforeseen events, user data will remain in the cloud. This way, important data will be safe, and users can have access to it from any device.
Access across multiple devices
Users expect to be able to log into a messaging app from multiple devices. That’s why popular messaging apps have versions for different platforms — smartphones, tablets, and desktops.
Synchronization is important not only for messengers but also for any other cross-platform application
The app must ensure that messages, notifications, and settings are consistent across all platforms. To do this, you need to provide high-quality data synchronization. Again, cloud services can help here.
Regulatory compliance
Not all messaging apps comply with data protection and privacy regulations. And if you’re developing a corporate messenger, you should consider complying with regulations like GDPR and CCPA. They set strict rules for collecting, storing, and processing user data. Non-compliance can lead to large fines and damage the app’s reputation.
At the same time, compliance can compromise the privacy of user data. For example, governments may require access to data under legitimate circumstances or for the purpose of content moderation. We recommend consulting with legal experts to balance regulatory requirements with user security.
Choosing monetization strategy
The core features of the app should always be free. After that — there are many ways to monetize your creation.
The best example is Telegram, which has a freemium model. The basic features are free without significant restrictions, which doesn’t ruin the user experience. But at the same time, Premium offers features that all users can enjoy. These include an increased file-sharing limit, faster download speed, voice-to-text conversion, and more.
Analysis of popular chat apps
Let’s take a look at three popular messaging apps mentioned earlier — highlight their features and provide approximate development costs.
Launched in 2009, WhatsApp was originally created as a tool for sharing statuses but soon became a messaging platform. Now owned by Meta, it is one of the most popular messengers in the world.

Facebook Messenger
Facebook Messenger, also owned by Meta, was launched in 2011. Messenger was originally part of Facebook’s social network, but over time, the company decided to make it a separate app. Messenger also allows users to send messages without having a Facebook account. The application evolved rapidly, with new features appearing: calls, stickers, and sending money.
Features:
-
- Text, voice, and video messages
- Voice and video calls
- Media and file sharing
- Group chats
- Status updates
- Business accounts and bots

Development cost: from $150,000
Key differences
These apps are similar in many ways, but there are still notable differences between them.
| Criteria | Facebook Messenger | ||
| Popularity | Large user base in countries like India, Brazil, and across Europe | Dominates the Chinese market | Popular in North America and parts of Europe |
| Privacy | Has end-to-end encryption | Doesn’t have full end-to-end encryption | Doesn’t have end-to-end encryption, but has “Secret Conversations” mode with encryption |
| Localization | Available in 40+ languages on iOS and 60+ languages on Android | Localized for China. The global app lacks some features seen in the Chinese version | Available in 111 languages |
| Level of complexity | Low, focused on messaging and communication | High, has a wide array of features, including integrated apps | Medium, has games and bots |
What factors affect the messaging app development price
If you want to create a messaging app, pay attention to two factors influencing the cost of the chat app development.
-
- Project complexity. The price depends on how big and complex your future messenger will be. You have to increase your budget according to your needs. On the other hand, if you want to develop an MVP, you can focus on high-priority features and improve your chat application later.
- Hiring option. To build a messaging app, you need a team. There are three main groups of app developers: freelancers, in-house teams, and outsourcing teams. The development costs with each group are different. Most freelancers have lower rates. If you want to hire an in-house team, you have to set up an office with all the facilities. With outsourcing, you get both effective communication and lower costs.
How much does it cost to make a messaging app?
We reached the most important part of the article — estimated costs and timelines. The chat app development involves a team of developers, UX designers, product managers, and QA specialists. And everyone needs to be paid 🙂
Our philosophy is to be as open and transparent as possible, so we always discuss prices and timeframes beforehand. We offer a full-cycle development of a React Native app from scratch.
