Development of Signal was started by Open Whisper Systems, creator of TextSecure, which used end-to-end encryption to secure the transmission of instant messages, group messages, attachments and media messages to other TextSecure users. However, it lacks the usership of the Messages and Messenger apps because it is not a pre-loaded default app inside phones. Signal is probably the best all-around bet when it comes to reach, security, and privacy-enabled features.
