Best messaging app for security

By G-Mo (Pcmac user)

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 the app. 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.
An inconvenient communication app

By 程序员之家 (Pcmac user)

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 the app’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 the app 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 the app. Get this app and spread the word. Remember freedom means “No Big Brother!”
Best app in the entire App Store

By PurpleMesa (Pcmac user)

No need to give your phone number out to anyone. the app 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 the app 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 the app since the start and their developers come with constant improvements and updates. I love this app because it means freedom.
