Everybody is so negative here. Ok rolling your own security protocol might not be the best move. However, they want to be competetive with whatsapp.

Most people who try to make a whatsapp killer suck in uix. But this app is really good and fast. I think its better than whatsapp in a multitude of terms.

Okay, there are improvements. But I can submit a pull request to the android app and improve it myself! How Awesome!
