Messenger Comparison Table

This is not intended to be an extremely comprehensive list, but enough to get a grasp on the situation.

The only client for now that we recommend is Conversations, a top notch XMPP client, fully supports the OMEMO XEP, is easy on the battery, and doesn't force you into a walled garden. It is not the easiest thing getting your friends and family to switch apps, so at the very least any apps with end-to-end encryption support should always be preferred over apps without.

As noted below the Signal protocol (double ratchet) is the current gold standard for end-to-end asynchronous messaging encryption.
