User reviews affect conversion to installs and app rating. Featured and helpful reviews are the first to be noticed by users and in case of no response can affect download rate. This is why it is highly recommended to reply to them.

This looks like a messaging app written by people who take security seriously. Well done. I’m only taking off one star because the onboarding process was a mess. At one point, you’re asked to enter a password, and again to verify it. That’s all fine, but the password fields are so far down the page that the on-screen keyboard completely covers the second one — and the page doesn’t allow scrolling vertically! Eventually I discovered a workaround (tap Passwords, then Cancel, then tap the second password field, then blindly type your password on the keyboard that appears). But this is really something that should have been caught in testing. This makes it impossible (AFAICT) to paste a password from the clipboard, which discourages the use of strong passwords from a password manager. And that’s not good for security. Aside from that one major inconvenience, though, this looks like a great app.

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.

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 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!”

No need to give your phone number out to anyone. THREEMA gives you an ID which you use instead of your phone number. No other secure messaging application allows you to protect your phone number in this way. Also, because you pay for THREEMA you know exactly why they’re doing what they’re doing. For money from you. You’re paying and this your data isn’t the price. I’ve been with THREEMA since the start and their developers come with constant improvements and updates. I love this app because it means freedom.

Threema is the world’s favorite secure messenger and keeps your data out of the hands of hackers, corporations and governments. Threema can be used completely anonymously, allows to make end-to-end encrypted voice calls, and offers every feature one would expect from a state-of-the-art instant messenger. With Threema Web, you can also use Threema from your Desktop.

PRIVACY AND ANONYMITY
Threema is designed to generate as little

data on servers as possible – this is a core part of our concept. Group memberships and contact lists are managed on your device only, and never stored on our servers. Messages are immediately deleted after they have been delivered. Local files are stored encrypted on your mobile phone or tablet. All this effectively prevents the collection and misuse of your personal information, including meta data. Threema is fully compliant with the European privacy legislation (GDPR).

HIGHEST ENCRYPTION STRENGTH
Threema encrypts ALL your communications END-TO-END including messages, voice calls, group chats, media files and even status messages. You can rest assured that only the intended recipient can read your chats, and nobody else – not even us. Threema uses the trusted open source NaCl cryptography library for encryption. The encryption keys are generated and safely stored on user’s devices to prevent backdoor access or copies.
