No TLS support - very bad security
The UI is brilliantly simple. I really want to love this app. But there is zero support for TLS (encrypted sign in) or SRTP (encryption of call data), meaning everything you do is sent totally unencrypted over the Internet.
This is an *insanely* bad oversight. If you use this app, make sure its signed out before you login to a public WiFi network. It would be trivially easy for anyone on else on the same public WiFi network to hijack your login credentials if you use this app.
