Reliable Silence communicates using encrypted SMS messages. No servers or internet connection required.
Private Silence provides end-to-end encryption for your messages using the painstakingly engineered Signal encryption protocol.
Safe All messages are encrypted locally, so if your phone is lost or stolen, your messages are protected.
Open Source Silence is Free and Open Source, enabling anyone to verify its security by auditing the code.
