Signal uses open source, end-to-end encryption to keep your messages to another Signal user secure and private. It installs on your Android and replaces your default messaging app. (On iPhone it's a separate app.) It's super easy to use. You can still send messages to people who don't have it, but I'd encourage everyone to use it. Plain SMS messages are routinely recorded and stored forever without your persmission. Signal combats that in a very user friendly way.
