CryptMee 0.3.2 is available on OpenRepos:
https://openrepos.net/content/chrm/cryptmee

It has a build-in chat UI, so you can easily make encrypted conversations.
Simple fingerprint management is also possible (remove, verify).

Next release will be a complete replacement for the stock chat UI. It will support plain text messages, emojis and SMP verification for fingerprints.

Have a lot of fun!
