Threema is posing a serious threat to the dominance of WhatsApp in the field of secured mobile messaging. The secure messaging app boasts of having end-to-end encryption for all data being transmitted to its servers.

Users of the private messaging app keep the private keys or IDs in their devices which prevents server administrators from decrypting data.

This encrypted messages app also offers all the features that you would expect from a mobile messenger. Developed by a Swiss startup called Threema GMBH, the app is compatible with iPhone, iPad, and iPod touch. Continue reading our Threema app review for more details on all that this app has to offer. 



The Most Secure Environment for Mobile Conversations

Privacy is one of the leading concerns of people who use mobile messaging platforms. In the light of official snooping and hacking by cyber criminals, more and more mobile users are looking for a secured platform where they can communicate safely.

If you are worried about your privacy when you send instant messages to your friends and colleagues, then you should consider installing Threema in your iOS device.

Threema is a secured mobile messaging app developed by a team of young Swiss engineers. It hosts its servers in Switzerland and offers a standalone platform that enjoys multi-layer encryption.

When you use this app, all your messages are encrypted. Delivered messages are also deleted immediately from Threema’s servers. This protocol prevents data thieves from stealing your information.

The app does not require you to submit private data such as email address, name, and contact information. When you open this app for the first time, it will create a random user ID for you which will be stored in your device.

You will then be asked to create a paired private key by randomly swiping your finger over a number matrix. A unique QR code will then be created which will serve as your ID validation.

After completing the initial setup, you can now use Threema just like any other mobile messenger. The difference is that you will enjoy better peace of mind because your messages and identity are being encrypted.

Threema uses the latest security protocols designed to prevent snooping. It offers state of the art encryption technology to protect your messages. It also allows you to remain anonymous because no private data will be collected from you.

One of the best features of Threema is the easy sign-up process. A random ID and a security key will be generated for you. This information will be saved in your device so you can log-in automatically.

The app offers a passcode generator which serves as another layer of personal security. You can use a passcode to lock the app in order to prevent other people from reading your messages.

And lastly, Threema offers an intuitive messaging platform which you can use to send text messages, images, videos, and voice messages. The app offers indicators to show whether your messages have been delivered or read.
