BlockScribe alternatives

I've been using Stealthy since it first launched as a desktop app. Now that it's a native mobile app, the experience has gotten significantly better. The channels feature is great because you start using the app without ever feeling like you're alone. Then, once you're comfortable, you can start having private conversations like you would with any messaging app. BUT those conversations are encrypted. And they're decrypt-able only by you.

My friends advised me this app some weeks ago, I find it really useful in today's world, especially in Russia, where every step you make in internet is being watched by government.
