Well executed but missing some features – Threema. The Secure Messenger Review
On the security side the application is very well executed. On the messaging side there are a few features that would be desirable to have;
The ability to quote a picture.
Read receipts on messages in group chats (who in the group has seen your message).
Mentions that work with chat muting for iOS like the Android version.
