How to build a messaging app?

A series of discussions and decisions are taken at the beginning for making a journey successful till the end. Whether you belong from a technological or non-technological background, all you need to do is to start from basics or let say doing some homework before beginning with the idea of transforming the app into an actual product. Your resources may allow you to build a chat app by yourself or hire a mobile app development company, but having a clear mindset on what is needed to develop is important because a need is the basic idea of any creation. Here are some steps that you must go through while aiming to build a robust chat app.

A. Choose Platform-Hybrid or Native

Before starting the app development process, first, you have to choose the platform for your app. Because many of you would be keen to know how to create a chat application in Android whereas some of you may want to build a chat app for iPhone users or some may want both. The specification of which type of mobile users you are aiming will determine whether you would choose a hybrid app or a native app.


Native apps provide an enhanced experience and better functionality to users, but they are platform-specific, i.e., either iOS or Android. Also, if your target audience is wider than native apps will cost you a lot. A simple solution for targeting a wider audience is to go for a hybrid app.

B. Specify Target Audience

Decide the target audience of your chatting app. Are you making this app for the general population or making it for high-class business professionals? Whether you are building an instant messaging application for a business level or enterprise-level? Select your audience because this will help you in selecting the features that you would need to incorporate within your chatting app.

There are so many features that you would like to incorporate in your app, including chatbots, artificial intelligence, IoT integration, and many others, but defining your audience will help you in drawing the line.

C. Scope out the minimum viable product

The first version of your app must have a minimal product that only offers the core features. Further iterations would include more refined features. From the minimal core features to the new iterations as technology evolves, the scope of your messaging app can vary a lot.

D. Development of the app

Now you got the final picture of your product; it’s time to get started with the actual development. If you are not an expert, then you can build chat app by hiring a talented crew of developers, or another option is to create chat app free with various online platforms. Keep an eye on the budget. The initial phase for hiring a developer will require extensive and in-depth research. However, the end product will be worth the wait and the time that you would put in searching for the right developer. Because only the right developer will make your journey successful.

E. Incorporate Changes

The rapidly changing and ever-emerging technologies ensure that the developed messaging apps get continuously updated so that competition stays relevant in the chatting market. The competition starts with the industry leaders keeping WhatsApp on the top; the user experience must remain in contact with these competing apps; otherwise, you are out of the chatting app development industry.

Every journey has some roadblocks which are there to pave your way towards the success. A messaging app should be a Product-Market Fit. Chatting app development would require a lot of resources; that’s why you need to consider its monetization aspect as well. Whether you offer an advertisement based plan or a subscription-based model, the monetization aspect must be in place to incorporate all future iterations of your messaging app for ensuring the long-term profitability of your app. Here we will tell you the ten must-have things to build a chat app like WhatsApp.
