I own a small business and needed a way to communicate with my employees and pass sensitive information. Our experience has been so positive, that we've begun to use it as our primary means of communication on mobile devices. Highly recommend!

Finally, an app that is fully and truly end-to-end encrypted! The fact that we can video chat, voice chat, and message all in one place, and have it all be encrypted is fantastic! My team and I live in different places across the country, and this gives us a safe way to communicate, apart from eavesdropping and listening ears. Thank you so much!

Can't start it because I can't click the continue button as it is under my home screen button

It would be really nice if somewhere in your descriptions of this amazing sounding app, that currently appears to be free, that it is in fact a subscription based app. And maybe some notation about whether the average person can purchase said subscription.
