App security is really low

Web browsers have had since ages a small lock to tell their users when they were securely connected to a web server.

Apps, especially those for mobiles, do not expose this information. It is very difficult to know if they use proper encryption, or that they even check the validity of the encryption certificates (when using methods such as SSL or TLS). Without such encryption, user credentials (login and password) and the exchanged personal data can easily be snooped.

App makers should mandatorily use encryption for communication. And they should use certificates to make sure they connect to the expected server. And they should expose that to the user interface!
