Chatter is a truly secure messaging app. To chat with your friends, simply connect over Bluetooth through Chatter. This will share a unique encryption key with your friends devices. All messages are then encrypted and sent over the internet. Only you and your friends have the ability to decrypt these messages because of this unique key.
Why?
Communication over the internet is not secure. Hackers are becoming increasingly better at spying and decrypting internet traffic as time goes on. However Chatter makes it virtually impossible for someone to decrypt your messages because your encryption key isnt shared over the internet. It is shared over bluetooth which is extremely hard to intercept.
