Wire[1] is also an excellent option. Unlike Open Whisper Systems they wont hang you from a tree for building a third party app. Signal wont work without Gapps or Google Play Services on your Android phone and Google Chrome for desktop.
Signal is pseudo-open-source but will not allow you to use it except via the closed-source google play services, so I still wouldn't have confidence in it.

Curious if you know why the crypto is half-baked. Has it been broken?
edit: found Signal server, I think: https://github.com/WhisperSystems/TextSecure-Server
Nice it's out there. This will help Signal live a long time.

Why must things be provably sure to have any value?
