Signal is an Android application for secure messaging and the protection of private communication. Users can set a self-destruction timer for disappearing correspondence as an additional measure.
Encryption and reliability
This popular application can be used for high-fidelity messaging and making calls including video. The platform offers end-to-end encryption powered by an open-source protocol. Besides, Signal is an independent nonprofit messenger. There is no tracking of data about your actions or texts. Similarly, you will never be bothered by advertisements.
The app provides optimization for sending messages in slow networks. However, the quality of audio and especially video calls may still be greatly affected if your connection is not good enough.
Customizable messenger
Users are able to set custom sounds and alerts for different contacts as well as change UI to the dark theme. Constant notifications can be annoying, so Signal conveniently allows to make them silent. It may also be beneficial to manage screentime and concentrate on productivity.
To help users find each other, the service supports phone numbers. The application scans the list of contacts on your mobile device and connects you to the persons who already use the messenger. Naturally, it is always possible to hide your number from being found.
If you want to evaluate the security of your system, you can try the ANDRAX app for conducting a network penetration test.
