The dashboard works as an app on your phone. It gets its own icon, opens full screen and updates by itself.
Android
- Open the site in Chrome and log in.
- Tap Account → Install app on this phone, or Chrome's menu ⋮ → Install app.
- Tap Install.
iPhone
- Open the site in Safari (other browsers can't install apps on iPhone).
- Tap the Share button.
- Tap Add to Home Screen, then Add.
Your automatic replies keep running whether or not the app is open.
