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. JohnFastman • Nov 2016 • 11 agrees and 2 disagrees Disagree Agree Desktop support via Chrome App only. Are you serious?
