Instant Messaging is the primary feature of all OTT Messaging Apps like WhatsApp or Viber. This feature facilitates users to exchange messages in a nearly real-time situation.

All the app-to-app messages are free of cost. Users only need an internet connection which is the basic requirement for these apps. One-to-One Messaging and Group Chat enables users to communicate in real-time from different locations at the same time.

Users have various options to create groups and sub-groups, and also control the media sharing in them. This type of communication is very useful for personal and business purposes.

Users can communicate with their family members creating personal groups. Similarly, professionals can create groups of colleagues to share product or business-related updates from time-to-time.


Registration is necessary for any user to start using these apps. The registration page in the app lets the users register and sign in. Authentication process via SMS, call or email verification follows the registration.

These authentications are necessary to ensure the validity of users. After successful completion of these registration processes, users can start to set up their profiles. This step requires the addition of their personal information and photos as per their preference.

Voice & Video Calling – with Group Calls

OTT Messaging apps like WhatsApp are not only restricted to the messaging feature. Although many apps may opt for some dedicated features, it is also possible to include various other attributes as well.

While call charges are still high via traditional services, calls through these apps are mostly free of cost. Although there is some basic criteria to enjoy the free calling feature like the presence of an internet connection and the requirement to have the same app on both sides.

Users can call their contacts for free from any country with an audio calling feature. Other features like adding multiple contacts and holding conference calls can also be enjoyed.

Video calling allows visual communication between users along with the audio. The users can further hold group video call conversations.

Contact Integration

The contact integration feature of the app syncs the contact of the user into the app. This process saves the hassle of adding each contact to the app separately.

Permission for adding the contacts is asked by the app when a user starts using it. Most OTT apps nowadays have this feature as it provides users with some added convenience. Additionally, your customers can directly search if their friends are using the same app.

Sharing Options

file sharing

The option of file sharing is an essential one and it helps users in many aspects. Users can share all kinds of media and documents, namely images, videos, links, contacts, locations, voice notes, and files in other formats.

For personal usage as well as for business or professional purposes, this feature has its usefulness.

This feature offers businesses and professionals the flexibility to share their work-related files and necessary documents with a single tap from their phone at any time, irrespective of their location.

On the personal domain, sharing files make the whole user experience better and also enjoyable. Nowadays, stickers and memes are most trending in messaging app world.

Presence Management

People put status updates with texts, images, etc. Also, they check-out status of other people in their contact list. This feature is found in all the popular chat apps like WhatsApp, Facebook and many more.

Profile presence option is one of the most iconic app features. This must-have feature is beneficial for any present-day communication app. Presence management also includes stories and real-time updates as well i.e. the last time the user was online.



This is one most important features you need to take care of when you create your messenger app. The dashboard of the app will provide users with the options to add users to the ‘Favourites’ section for instant access. This feature aims to make the app more user-friendly. The segregation of the favourites from the rest saves user’s time in scrolling and searching the app repetitively.

A search option in the dashboard of these apps is of further help to the user. This enables the user to search specific contact and start group conversations. It offers a very easy-to-use interface.

When you decide to create your own WhatsApp like messaging app, you can think of going for advanced customization to offer essential features in your app’s dashboard. This makes the app user-friendly and subsequently helps it to rank amongst others.

Other Extra Features

The addition of extra features is subjective to individual choices. While building your own Messaging app like WhatsApp, if you feel the need to include something different than the rest or something more than what usual apps are offering, then it is totally up to you.

While the addition of extra features also has the potential for increasing the value of the app, it also has a downside. Too many features which are far from any immediate necessity may make the app clumsy.

Therefore, the addition of extra features depend on each brand, whatever they choose to include in their app. It can include location sharing, self- destruction of messages (after being read), customizable profiles (background colours, patterns, fonts, message scheduling and more).

Tech Stack for a WhatsApp like App:

Creating a new messaging app is a complex process as there are various technologies that you need to understand and embrace. Let’s take a walkthrough of the tech stack that you will need to create an app like WhatsApp. However, it should be noted that this may vary depending on the project requirements.

For Mobile Development

  • Programming Language

It is generally a set of instructions that is used by the developer to implement algorithms and perform a specific task. For chat app development on android, Kotlin and Java are two popular programming languages. For iOS Platform, Swift and Objective-C languages are recommended.

  • Local Storage

When it comes to local storage, Core Data, which is an object graph and persistence framework for Android. Relational data can be organized and managed using this framework. For data management on iOS platform, SQLite, which is an RDBMS, can be used.

  • Authentication

Authentication of users is a must to prevent fraud and spam. Before a user (both new and existing) starts using the app, recognition is done by verifying the user identity. It can be implemented via phone number, email, social media accounts, etc. For this, usually a third party API is used. For instance Facebook SDK and Twitter Kit are generally used to implement social authentication functionality in an app.

  • Preferences

Preferences are mainly used to configure an app and are exposed o users to let them customize the look and feel and behaviour of the app. These are basically pieces of information that are stored persistently. In Android, it is called Shared Preferences and in iOS, it is UserDefaults.

  • Chats

In Android, OkHttp is a client of Http that is efficient in loading and thus helps in saving bandwidth. For iOS, Starscream is the application that connects to a server web socket in order to send and receive data.

  • Voice and Video Calls

Video and Voice Calls promotes interactive communication. To enable this, WebRTC is used which is a free and open source communication technology that allows direct peer-to-peer communication for audio and video to work inside web browser pages. There is no need to install plugins or any apps.  It is supported by almost all major web browser companies such as Mozilla, Opera, Microsoft and Google.

  • Notifications

Push Notifications are essential for user engagement as they can turn one time users into long term consumers. For Android Platform, Firebase Cloud Messaging technology is a good choice. For iOS, you can go with the native push notifications. 

For Backend Development

  • Programming Language

Some of the useful and popular programming languages for backend development are JavaScript, Ruby, CSS3, HTML5.

  • Data Storage

Data storage is another important aspect of creating an app. Backend functionality should be defined in order to store user data such as text files, messages, pictures, etc. Databases like PostgreSQL, file storage services and web servers are used here.

  • Automation Framework

In order to make the testing process easier, efficient and less time consuming, there are several automation testing frameworks that can be used. Some of which are PhantomJS, Capybara, RSpec. These are based on best practices and assumptions that helps in accelerating the testing, which is why these are being used more often.

  • Server

Puma and nginx are two popular choices for web servers. While Puma emphasizes speed and efficient usage of memory, nginx is known for reverse-proxying and load balancing.

  • Key Value Storage

Redis or Remote Dictionary Server is an open-source and advanced in-memory data structure store that offers benefits like high performance and scalability.

  • Hosting

Amazon hosting services provides reliable, scalable and cost-effective computing resources using which you can host your application.

  • Data Processing

Since a messaging app includes chatting, there will be processing of lots of messages in almost real-time, which is done with the use of WebSockets. By establishing a strong connection between the app and server, WebSockets transfer data directly and thus offer high speed and consistent communication.

  • Data Sharing

File Sharing capabilities can be added to an app with the use of specific APIs and passing the data to servers through SOAP and RESTful APIs. This will allow users to share documents, photos, videos, etc. from the phone gallery and directly from the app.

If you’re really determined to create a messaging app, it is recommended to think beyond the mobile platforms. In simple words, you can make a multi-platform messaging app by creating a web version of it, besides the Android and iOS. You can read more about web messenger here.
