It’s a great secure messaging app with huge potential but still needs some improvement. Hope it can support Mac OS soon!

You should be able to retract your messages and it doesn’t have this feature. Or Message expiration where messages get completely dusted after certain amount of time

I love threema. Five stars. After the most recent update, I can barely type. It locks up half of the time. This is utter nonsense! (iPhone 7 Plus 256GB) -- devs, please address! (Then I will happily rate this back to 5 stars)

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!”

Such an inconvenient communication app for voice-messages. It doesn’t support running in iOS-background, which means it can’t automatically download voice-messages or images you received. Every time you get a incoming-voice notification, you have to open this app and tap the voice-message you received and wait for a long while to download it. If you don’t live in Europe, I strongly suggest you not to using it, because downloading voices-messages from Threema’s sever takes really long time. Not even to mention that if you receive more than one voice-messages, you have to tap them each one by one to download, waiting and waiting for these downloading processes. Too annoying!! What an era do we live in? Almost every communication app is now having this feature downloading media automatically.

I’ve used Threema fo almost 3 years. During this time, this app has exploded with features not seen on other messengers (see vendor’s description for the app). The technical support is impeccable; I’ve always received a clear and helpful response with a day. These people care about their customers. With no doubt, I’ve received outstanding value going with Threema. If you need a great communication tool, look no further.

Only thing I’d change is the icon. If your using this app and don’t want people to realize it’s a messaging app it’s kind of hard. The picture logo is literally a message bubble with a lock in it, which is pretty suspicious. Other than that I think it’s great.
