React messenger is like other messengers available in the market as of now with just a small change. Instead of using your profile picture on all messages it uses the real time picture using the fron’t camera.
This one does not keep too much message history, it will keep only a small number of recent messages, rest will be get deleted.
It also allows you to combine the front and back camera pictures together.
It is available on on iPhone as of now, and also it will require iOS7. older versions will not be supported.
