How to Build a Messaging App for Chats: Steps and Examples of Apps

Difficulty: Intermediate

Estimated Completion Time: 9 minutes

Recently, due to the blocking of many popular instant messengers in some countries, people have started to look for other, newer communication solutions. This means that now is a great time to launch your chatting application. Below you will find how to create a messaging app and how much it will cost.

Messaging Apps and Social Networks: What Is the Difference?

Before explaining how to develop a messaging app and describing its basic functionality and steps of the development process, we will briefly overview the difference between such apps and social networking apps. The second type is characterized by the ability to display messages (posts) to many users at once. Thus, they imply a one-to-many type of interaction. As for instant messengers, their main purpose is to provide convenient one-on-one communication. 

Of course, modern chatting applications have already adopted many of the functions of social networks, so this fundamental difference is already quite blurry today.

Features of a Successful Messaging Application

Now, we offer you to consider the basic features for your future mobile solution in our guide to creating a messaging app. 

Authentication and authorization form

First, you should make a user authentication and authorization form that would ask each user for personal data for secure login, whether it be a mobile phone number or just a nickname (as is the case with peer-to-peer solutions).

Text messages

You have to decide on a mechanism for sending messages (decentralized or server-based, depending on the architecture of your app). At the same time, you need to think about how messages will be displayed to users on devices, what the keyboard for typing will look like, whether there will be stickers and emojis, etc.


The average messenger should have a Contacts directory, which contains saved phone numbers or accounts of other users, and a Search option. In this case, Contacts must be integrated with a similar directory on the user’s device.

File sharing

In addition to sending text messages, users of an ordinary chatting application should also be able to send and receive file data. Think about how they will be stored on your web servers (and whether they will be stored there at all)—how long, in what location, etc.

Voice messages and voice calls

Many instant messengers today know how to send not only text but also voice messages. Some of them even provide the ability to change the voice or add various audio effects. Also, chatting applications should be used as an alternative to a regular phone—for free live voice communication. For the safety of users, you can provide the option to generate a unique code during a call, as in Telegram.

Video messages and video calls

As a bonus feature, you can offer to send video messages, like Telegram and WhatsApp do. And finally, in addition to the voice call option, add the video call option to expand your solution to the level of Skype, Zoom, Google Meets, etc.

5 Main Steps for Creating a Messaging App

Let’s find out how to build an app for messaging and what the main stages you have to go through with your development team to launch it are.

Marketing research

The first step of our guide to building a chat app is market research. As you know, any process of developing applications for a broad target audience begins with marketing research. At this stage, your contracting team identifies potential competitors in your business niche, identifies their strengths and weaknesses, draws up a portrait of the average client, and analyzes which features will be most valuable to the target audience.

Compiling a list of specifications

Once you and your team understand what your target audience currently expects from a chatting application, it’s time to list the exact requirements for the future product—the software requirements specification (SRS). This way, your contractors won’t be able to veer off course and go against your product vision.


When the specifications are ready, designers can already create a basic sketch of your product and, if possible, demonstrate some of its functionality. This way, you will get a visual example of the app’s final version, and your contractors will make sure that you understood each other correctly in the previous step.

Front-end and back-end development

After the design procedure is finished, your team can proceed to the product’s development. Since instant messengers work with the help of the Internet, the development process implies the synchronous work of front-end and back-end commands.


As individual application modules are built, they are tested by developers for compliance with the specifications we talked about above. If the actual state of things does not meet these requirements, the product is returned to the developers for rework and bug fixes.


When the product is complete and fully meets its specifications, the development team releases it to the public—on App Store or Google Play, depending on the platform.

Updates and tech support

This step ends our guide to creating a chat app. It includes fixing bugs found after the release of the product and launching updates that may be required as the needs of the target audience and your business goals change.

Cost of Developing a Messaging App

Now that you know how to make a chat application, you may wonder how much it costs. 

As you may understand, the calculation depends on the functionality you plan to implement, the number of supported platforms (iOS, Android, web version), the speed of development, as well as the location and the company where your dedicated team of specialists works. However, averaging the budget of most similar projects we have dealt with, prices start from $20,000–$25,000 and can go to $80,000+ depending on all the above factors.
