With Dark SMS you can establish secret conversation with anyone. Your messages will be end-to-end encrypted using crack-proof and state-of-the-art cipher and key-exchange algorithms.
For sure Dark SMS can be used for normal text messaging, exchanging text messages. Application doesn't use any Internet connections, any intermediate servers - nothing except short message service provided by your mobile carrier.
To establish encrypted private conversation you have to invite your party and your remote party should accept invitation. Exchange by invitations should be done only once. After that you can send and receive secure texts. Also, unlike any other applications your SMS can be protected directly on your smartphone, so only you can see message using your own password.
Noone except you and your party could see your conversation - even your mobile operator or any other intercepting agents.
Dark SMS is award winning application short-listed by Electronic Frontier Foundation to 2014 EFF Crypto Usability Prize (EFF CUP) as one of the best applications implementing complicated crypto algorithms in simple and user-oriented way.
