The most important features in a chat app

The messaging app features you'll need are based on your goals. So, feature development is critical because other factors—such as the time, cost and technology stack—will depend on it. Our team is ready to help incorporate the key features you really need and identify those that can wait for later.


This function is the core of any chat app. Users should be able to send text messages to each other, edit them if necessary, and search chats and messages for the info they need. Quick, smooth messaging is the key.

Audio and video calls

The popularity of calling integration in chat apps continues to grow. It helps users save money on mobile calls and talk to each other in real time. Group calling is useful too, especially for working teams and circles of friends.

Group chats

As with group calls, group chats let users keep up with their friends and loved ones. Family members can communicate over distances and time zones, friends can share funny videos and memes, and colleagues can discuss important topics.


Funny, emotional pictures make even the simplest message more fun. They help people convey their emotions more readily, so communication becomes more colorful. Also, your personalized stickers can become a desirable feature among users.

Cloud storage and backup

No one likes their device being clogged with cache, but everyone wants to have constant access to messages. Cloud storage makes all of your texts and files available from any device without robbing you of valuable space.


Chatbots make chat applications more user-friendly and intuitive. They’re able to cover repetitive tasks for the team and help businesses conduct marketing campaigns. It’s also possible to leverage chatbots with automatic or smart answers.

Security and privacy

Today, guaranteed data security is a strong motivation for users to choose messaging apps. Sophisticated encryption shields confidential information from attackers and makes your app the one to trust.

Voice and video attachments

Your messenger should also be able to send any type of various attachments, including audio, video, documents, maps, and other types of custom attachments that are relevant to a particular chat app case.

Link preview

Users will be thrilled with your implementation of this feature. When one person sends a link to another, a messaging app shows a small preview with a page title and some of the content, such as text and/or an image.

Statuses and typing indicators

The feature of statuses to users is another contribution to user-friendliness in a chat app. Users should see the message statuses like “sent,” “seen,” “read,” “edited,” and understand if the person on the other end is typing or not.
