After downloading
  1. Open the downloaded file and allow installing from this source.
  2. The app asks once for the server address, and remembers it.
  3. You can change it later in the app: Settings → App server → Change server.
Both apps can be installed together. They are separate apps with separate logins, so one device can be the manager and another the employee — or one phone can hold both.
