Features shown:
- Authorization by various methods: by call, by SMS, by login and password or by qr-code
- Messaging from a mobile application with office employees (users of the central database)
- The app works offline. That is, messages are delivered when there is a connection, but you can write them even in its absence.

The application can be downloaded and connected to your database, or you can use the demo mode without connecting to the server
