User reviews of Threema
I love this app as it seems to be one of the few out there doing encryption correctly. The usability is simple and clean.

It started well but now..... :( I started using it about a year ago and it was great. Now it's laggy. It takes a long time to send and deliver my msgs. Impossible to chat. The search function doesn't work. Two stars because I really liked it in the beginning!

Improvements needed 😐 to be a Good Messenger 😍 1:Add Custom Dp option……😞 2: Add Last seen Option……😓 3: Add Broadcast Msg Option……😌 4: Add Status Option/Feeling-Mood……😇 5: Instead of 3 different apps(plugins) "QrSacanner" & "Voice" they should merge into 1 single basic app……😒 6: Instead of apple smiles, these smiles look like android. Because we are user of android not of Apple……😖 7: Should be multi Device Support……😴…… 8: In Group there is no icon that the msg was sent or not(icon-not available) instead of long press and check sent status😯……

Really nice app! It has every essential feature that an app of this type should have. However, a Windows client, a Glympse live location tracking and (if possible) a voice call option would be more than welcome, thus making the app PERFECT.

Lollipop unfriendly Crashes on start up following contact sync. This is on a Samsung Note Edge. Reported via built in feedback. Twice. Nothing heard yet.

  Amazing! Using the proximity sensor for deciding which speaker to use is just brilliant! 😁
