Chat app developers is operated, basing on Presence Protocol (XMPP) and other similar systems and structures, while deploying upon the aspects of them. The app creates an account of a person with the usage of his or her phone number. So, thanks to sucha system, you are able to get two great benefits. The first one, is a proper level of security and a great simplicity, what is really essential in case if we talk about the modern applications. There is no need for a password, but a random one is created on the server side just for safety.
Talking about the client-side design, the choice of programming language depends on the device the application will run. For instance, Objective-C or Swift for iOS app platform, Java for Android one, and C# for Windows Phone. Even while having no programming and coding skills, you are still able to start the developmental process, basing on Android and iOS, what may allow you develop a chat application on a proper level.

Keep in mind that data security is the new trend, and it will definitely influence the chat app development cost. So don't be mean and provide chats with the next security features:
One thing you should know about how to develop a mobile chat app is that Internet connection is a must. For example, if you've been without Internet connection for a long time, there is a chance that you won't receive a message. That's how the message storage on WhatsApp works. The messages are saved on the corporation's server for 30 days. Then it will be removed permanently afterwards. So, be careful and be online.
Also, there should be an option to create a group chat where users can provide the subject of the conversation and add pictures to their messages. Recently, another handy feature has been released – the option to send similar message to several people at once. The Broadcast List has already become popular with users. As you can see, you are free to use different ideas and make your WhatsApp-like app even more customized.
Development time needed: 60-120 hours for both iOS app and Android app versions, and 80 hours for the development of backend.
While wondering how to create a chat application like WhatsApp, a question concerning how users will be registered might come up. There is no need to create an account because a user is connected to the app's database with his/her phone number, which is unique by default. The same thing with phone contacts. The app's software automatically checks if the numbers in the user's address book already exist in WhatsApp user's database. And if so, the numbers are added automatically in the app.
Development time needed: 16-24 hours for both iOS app and Android app platforms, and 8 hours for the development of backend.

Users are used to sending multimedia files via chat apps. Voice messages, pictures, and videos can be uploaded. This is a standard feature of any chat app. So it would be better to create a chat app for iOS and Android that has the same features too.
Development time needed: 20-40 hours for both iOS app and Android app platforms, and 40 hours for the development of backend.
The geolocation feature is a must and should be integrated into the application because of its usefulness to users. It would be impossible for you to get lost – just send the coordinates of the place you are in at that moment.
Both platforms offer solutions for geolocation integration into an app. Developers use Google Play location services API for Android and Core Location framework for iOS app. These features are regularly updated because they constantly receive newer data. The maps are displayed with special offers – Google Map Android API for the Android platform and the Map Kit framework for the iOS platform.
Development time needed: 16 hours for both iOS app and Android app platforms, and 4 hours for the development of backend.
To attract users, you can add a calling feature, just like WhatsApp and Viber already did. Furthermore, to create WhatsApp-like app, you will need to make these functions special. The application will use Internet traffic instead money or call minutes to make a call. A chat app with the calling feature usually allows VoIP phone calls, video chats and group calls, which can also be a video call as well. If you want to increase your app engagement and be successful with the app, include additional features like video editing or special effects, which will make the application stand out from the rest of similar applications.
Development time needed: 100-120 hours for both iOS app and Android app platforms, and 120 hours for the development of backend.
Talking about how to create a messaging app like WhatsApp, customers also wonder what additional functionalities can be considered. Status and live streaming are not the essential ones. Status feature is new to many chatting apps and even social media apps, and is considered a real boom in 2017. That is actually a feature, which makes it possible for the users, any of them, to share videos, photos, GIFs and messages in a special regime, which means, that all of the shared materials are going to disappear after the 24 hours. By the way, we do not have to forget, that the main feature, which has a direct influence on the communication between you and another person is the fact that both of you have the contact numbers of each other within your contact books. Actually, there is another nice feature, which made WhatsApp so special. Because of the usage of different tools you may be able to edit your stats with the usage of absolutely different and creative instruments, such as emojis, various fonts and media files. I believe, that people will not miss your application, if your real time chat app should be able to offer the user the same size of special functions and services.
Development time needed: 40 + 20-24 hours for both iOS app and Android app platforms, and 16 +8 hours for the development of backend.
When you create app like WhatsApp, in order to grow the number of active users you should explain to users what they can use the app for and encourage them to invite more friends to chat there. Slack has become a successful messenger because of the clear understanding of its value – “a chat app for team communication” where people look for teammates who need a secure place to chat. Before the iOS or Android chat app development begins, you need to decide who your target audience is and what their benefits will be for using your product.
You can also combine instant chatting with hashtags to give users the ability to share their content on the social media. This way, the chatting app will be promoted through multiple additional channels.
You might not know, but user retention rate is important for chat apps. Let them synchronize the app with their phone contacts and get notification every time a new person from their address book joins the app. Also, you can allow them get push notifications, which will draw their attention to the app as well.
Acquiring more users won't go well without constantly entertaining them. Make your application fun by adding different sets of emojis, stickers, gifs, etc. Also, add short video clips of popular movie moments, as this will help you promote the app, especially to the youth.
