The Cuebly app turns an iPhone or Android phone into a personal safety device. The app user can ask for help with one button, set a timer alarm, and receive messages from the platform. In the customer environment, the app is a device like any other personal alarm.
The bottom bar has:

Hold Send help! for 3 seconds to send an alarm (1). Switch your availability under Status (2). A running timer alarm shows at the top, with Cancel (3). The bottom bar (4) leads to Groups, Views and Settings.

The app confirms that the scenario started (2). A text message from a scenario or from the platform shows as a dialog; tap OK to close it (1).
The app tells the platform regularly that it is still running (a heartbeat): about every minute while the app is open, and about every 15 minutes when it runs in the background. The platform shows the app as online or offline. The app counts as offline when its connection to the platform closes, for example when the platform has not heard from it for a while. Phones decide themselves how often an app may run in the background, depending on battery, memory, charging and use. So an app in the background can switch between online and offline.
Messages and assistance requests reach apps that are online. That is why the onboarding asks to let the app run in the background.
The app has the same 10 languages as the platform. Choose the language in Settings; it does not depend on the language of your phone. See Supported languages.
