Cryptogram Messenger

Features Cryptogram Messenger

Cryptogram is a fast and secure messaging app built to make the communications process easier.You don't even need a password for your account - the authentication keys are stored on your iPhone and no one ever will know them.
Besides that, you don't need a username too!
Just show the QR-code from your profile to your friends and they would be able to find you and start the conversation.
You are still able to choose a username, so another people could find you.
