Enjoy using Threema!
Has a lot of good features, and works a majority of the time, but has quite a bit of bugs. One of the bugs it has is that sometimes, during a video call, I begin to hear an echo of my voice. Once I end the call and reestablish a new connection, the echo goes away. Another issue just arose when I got 16.2, which is I won’t be able to hear the person I’m having a video chat with through speaker, but shutting the app down helps. Also has other bugs such as not given the option to use the camera unless I hold down on the users name from the contact list which will then give me the option to take a photo. There are a few more, but I could be here for a while. Just hoping some of these things can get resolved because they are quite annoying. That said, good app overall.

Best messaging app for security
G-Mo
If you want a pretty messenger, stick with the Messages app, Facebook, or maybe Signal - they’re all “secure”. If you want a secure messenger, get Threema. It sends messages securely from device to device, not user to user, so you need to think a bit differently about using it, but that difference in thinking is “this message is encrypted on my device and sent to that other device, which I’ve confirmed is the correct device by scanning its barcode”. This is handy (and one of my main uses) because you know that your snarky comment isn’t going to show up on your wife’s computer as she’s projecting her screen in the conference room at work. True device to device encryption, plus the company’s location in Switzerland with physical control over its servers, combines to make this a very secure messaging app. Even if you’re just using it to send snarky notes about employers, it’s worth the price.
Amazing! Would love updates
adrianisafreakingbeast101
Been using threema for some time now and it is a great anonymous app and amazing privacy! I would love it & think it could be beneficial if they added an update where if you send a sticker it doesn’t automatically send to the chat as soon as u press it from your keyboard but rather an update where it puts the sticker in your text bubble before you press send so that you can maybe add more stickers, emoji, or text etc. or even change the sticker your sending so that stickers are not ONLY able to be sent as large stickers singularly and separately. Bringing Imessage features more to the app , not even Instagram has this feature in their keyboard, this would separate threema from as a messaging app from the others on another level!
Needs delete for everyone option & viewed option for received messages
Jale71
I like Threema but was horrified to discover that one cannot delete messages for everyone. I did not realize that all messages would remain on the receiver’s phone. I get confused on Threema when I have listened to an audio message because there is no indication that I have already listened to it. A check or something would be nice. If there are many audio messages and one gets interrupted, then it is unclear where to start relistening again. I do not like the red while recording messages, it is very distracting to the eye. I would prefer a milder color. I also like that in WhatsApp I can type a reply in the reply box while listening to a message but that does not work in Threema. Otherwise, I like the clean design of Threema and the privacy.
