As a hacker

Any time someone says they ahve military standard encryption, their product is shit.
Please, don't use shity buzzwords like that if you want to be taken seriously, especially by Security community.

Also, is it open source?

Can third parties (like me) perform their own tests? Will you have a penetration tester (like me) test the app before releasing?

Also, how are you dealing with "identity change"? (Eg. I change my phone)

And as far as design goes,it's pretty Ok :). I might offer a redesign later on.

Good luck. Following for updates.
