A free app for Android, by Flyperinc.
Flychat is the best way to read the messages of your favorite messengers. It lets you do everything you expect from a messaging app, like sending and receiving messages, but also offers you the convenience of being able to view the messages on a split-screen, while you are using another app.
It’s a simple, intuitive, and very easy-to-use application. Just install it on your device, set your messenger of choice, and start reading the messages on your phone.
If you use more than one messenger, you can add as many as you want. You can even set the size and color of the bubbles to your preference.
In addition, Flychat has a beautiful design and a clean interface that lets you focus on what you are doing.
