Love the app, but ever since the last update to iOS13 it’s not possible anymore to see the text you add to a picture before sending it to THREEMA.

Threema offers the best security of any encrypted messaging app available! Not only is it based in the pro-privacy country of Switzerland, but it has also been comprehensively audited by a reputable Swiss security firm and found to have no vulnerabilities. The other great thing that makes it unique is that only you have access to your private key and you can exchange public keys directly with friends and family, which proves the identity of your contacts. This robust authentication protects your communications to a greater degree than similar apps. For more confirmation, check out past Security Now podcasts for why Threema is the best and most secure messenger you can use. If you are looking for a messaging app that gets security right, look no further than Threema.

I’ve been using Threema for years It is by far the most safe and secure messaging app out there Once you pay for the original app, there are never any additional charges for any messages, pictures, videos, or texts sent... ever!! I used to pay a lot of money to send even just one text message to family members in Europe. Not anymore.. I hear this app is very popular in Europe, but somehow I don’t think it will ever catch on in the United States. But if you do purchase it, it is definitely worth it. You will need to tell your friends and your family members about the app because they need to have the app as well in order to communicate with you. Once anyone else has this app it’s the only way I communicate with them. They begin to use it too and it becomes your normal way of sending messages back and forth. Almost all of my text messages to people I know, go through Threema. Get this app and spread the word. Remember freedom means “No Big Brother!”

For me this app has been 5 stars but the latest app has unresponsive UI. The app crashes and hangs which it never did before.

I love Threema and the spirit of the developers' vision. I really trust this company. They just need a few additions. Needs a delete for everyone feature. This is very necessary for a number of reasons: error in typing, privacy, etc. Needs to make indicating bubbles of phone calls less intrusive, as they take up the same or more space as actual messages. Need conference calling. Near perfect app. Thank you. The ability to quote a picture...any message to or from. Also read receipts in group chats. Actually, this might catch on in the USA. I've got people looking at it. But still need to differentiate calls from actual messages in appearance.

This is a solid, secure messaging app and I enjoy using it. Though, there are a few features I feel need to be seriously reconsidered, or perhaps even removed. 1. The ability to export an entire conversation Into a zip file without the secondary users consent 2. The inability to block users Other than that, this is a pretty solid app. In the future however, I would also recommend adding group administration options.

App is also freezing since last update. Why do y’all keep screwing with it. Please add full Apple Watch support. This freezing is really messing with my system btw

Cool interface, and solid security protection from remote devices accessing information. I would recommend that they create a burn on read feature similar to wickr that deletes messages as they are read. Good protection unless someone has access to your physical device.
