In 2023, Telegram has seen approximately 20 million downloads in the United States and maintains a monthly user base of around 10 million. While these figures may be noteworthy for many applications, it's essential to note that the United States contributes to less than 2% of Telegram's global user base.

Telegram has made security its distinctive feature and claims that all its activities: chats, groups and media are encrypted. Telegram even changed headquarters jurisdiction several times to evade problematic regulations, now it’s Dubai.

Is There a Place for a New Messenger on Play Market?

If you are planning to make a messaging app, you should be ready to face high competition on apps market. Learning from top-rated messaging companies, we may conclude that the most important thing is to find your target audience and satisfy its demands, by providing rich functionality. For example, Slack has occupied its market by providing solutions for corporate needs. WhatsApp and Facebook Messenger demonstrate that two products with similar functionality, and even with similar interfaces, can successfully coexist on the market.

WeChat is popular due to its extended functionality and also Facebook is blocked in some Asian regions. Telegram took its audience by claiming they get high-level security and privacy with the app.

Just think, how many messengers you have on your mobile phone. Why do you have several? Most likely, you use different applications for different purposes: one for work, another for chatting with friends, some more may be for studies and business development.

Your mobile messaging app for startup should combine functions of different messengers and match various purposes, or it might make a step up and bring an originally new solution to the market. In a constantly changing world, there is always a place for new creative ideas!

However, as soon as you have an idea, you also have a question how to make a chat app and avoid development pitfalls. Let’s see into a process a bit.

How To Build A Messaging App Step by Step?

Discovery phase

To create messenger app and not mess up completely, you should follow the common process of a mobile app development. The first stage of which is discovery. Stfalcon always starts its projects from market research: who the current players are, what they offer, what products exist and what features are implemented, which user pains they relieve. Then you should understand the users as well: what they seek in the solutions they use, what they value most, what pains they still have and what you can offer to beat competitors. When all the questions are answered and the client’s requirements are taken into account, we create the general concept of the product-to-be.


The concept approved by the customer; we move on to design stage. To make an instant messaging app really instant you should craft an intuitive UI, without sacrificing functionality. With such a severe competition, all the slightest details should be considered and polished at this stage. We also agree the design of any product with the customer.


The business logic of any application is wrapped up in an external server, which is an essential medium an app turns to. The server centralizes the logic of the solution and serves as a mediator which stores and transmits messages. We traditionally use PHP Symfony for backend development to make its work smooth.

Mobile App Development

Finally, we proceed to the solution itself and create iphone text messaging app or Android, or both, depending on the task. As a rule, Stfalcon developers would choose Kotlin make a messenger app for android or turn to Swift for iOS application.

Technical Implementation

Summarizing all the above we can conclude that to make a chat program, the following key features should be implemented in it:


Since the sign up is usually realized via smartphone, it’s reasonable to make it through using a mobile phone number, with an SMS for confirmation. Then a special library may be used. Social Media authorization is also an option.

Real-Time Events

To notify a user about receiving a new message, friend request, statuses updates in real time push notifications and WebSocket protocol are mostly used. To make a chat application for corporate usage on our client’s request we also used

  • Mobile database Realm
  • Library DataBinding
  • RESTful API
  • Library Retrofit 2.0
  • Firebase Cloud Messaging.

Files and images sharing

At present to make a texting app is not enough to gain the audience, users share photos, videos, files and links. We have developed a library to implement the necessary algorithms for the purpose.

Voice messages

Modern life is dynamic the option to record a voice message is already a must for the apps of such kind. It should be played in the chat window, and have a pause and rewind features. Fortunately a standard set of OS functions can help to implement it.

Voice calls

You may postpone this feature implementation, since it’s rather complex and will come to you at cost. PJSIP library, providing multimedia communication, can be used for VoIP functionality.

Our Experience

Stfalcon has experience with messenger app development, but we have created the open source library ChatKit - a set of UI elements, for the simple realization of moderately complex chats. It contains users’ dialog list, message thread, and message field and is designed for easy implementation of chat representation logic.

Library of UI elements for easy chats implementation

Besides, a few years ago our company has developed a  Thismo messenger with real-time events, like WhatsApp, but for corporate users, like Slack.
