Good App, Needs improvements... – Threema. The Secure Messenger Review
The app works fine and has many pros. It's not tied to a phone number which is nice. Though I'm unsure how much I can trust the app I'm sure it is good enough for general texting and photo sharing.
Pros:
1) Pin to open the app (optional)
2) Read receipt
3) Very customizable
4) you can see when someone is responding.
5) Group messaging
Cons:
1) No audio calling (VoIP)
2) Open up the code for security audits by everyone
Until number two happens, have Signal on your phone for calls and more private conversations.
