Approximately two weeks ago, Open Whisper Systems announced the merger of two of its Android apps, Redphone (secure calling) and TextSecure (encrypted messaging) into one: Signal for Android. This is a counterpart to Signal for iOS, created by the same team. A Chrome extension is forthcoming.

Signal has been getting a lot of love from the security community (Snowden, Schneier, etc) specifically for it's user-friendliness --- something that has prevented the adoption of other crypto software.

The encrypted messaging algorithm seems to be a version of OTR modified for asynchronous mobile environments. Some version of this has been implemented in CyanogenMod as WhisperPush and WhatsApp.

Their blog has a lot of nerdy crypto detail for those interested. For example: deniability, forward secrecy, calling network.

All of their code is open source and funded by donations. Donations are also possible using bitcoin. Accepted pull requests get a payout using another of their projects, Bithub (code).
