5 stars: We rely on this app among the company. It is proven to be secured, fast and reliable. The voice calls are also amazing while being encrypted. I wish it could support deterministic upload progress bar like decent chat services.
4 stars: Poorly supported, but decent if you cope with lack of a fully functional Windows/Mac app. MDM is intuitive, pricing is modest. Seems to be secure, but I don't think I'll pay for another year of service.
4 stars: Wish it wasn't so difficult to reply to a message containing a link...
3 stars: Missing group calls!!! Otherwise works well in 80% of cases. In the rest, the call keeps initializing, or the recipient tries to answer in vain. Need to call again and hope it'll work. Usually it does, on the second try.
3 stars: Delete for all option required, pls provide as soon as possible. Other wise it's ok.
2 stars: When you buy a new phone and you try to install threema on your new phone it is virtually impossible and I have tried everything. . This app is not user-friendly.
2 stars: Very unreliable. Calls wont go through most of the time. No ability to leave VM. At least ok for IM only. Limited group capability.
