Mustercall

Mustercall is a check-in alarm for anyone who works or lives alone.

Arm a session before you start. Mustercall pings you when your next check-in is due, and you tap the button to say you are safe. Miss one, and the person you nominated is emailed automatically — with the time of the missed check-in and, if you turned it on, the last place you were. You do not have to touch anything for that to happen.

Built for the days when nobody would notice.

WHAT IT DOES

· Arm in two taps — Site days (your working hours, every 2 hours) or ad hoc.
· Check in with one press. Hold to confirm, so a pocket tap cannot silence it.
· The alarm takes over the screen and rings when it fires, so a missed check-in reaches you even in a noisy place.
· Your nominated contact gets one plain email: who, when, and where.
· Practise the whole chain first with the drill — it runs the real countdown and the real alarm and emails nobody.
· Everything stays on your phone. No account, no sign-up, no analytics, no ads.

HONEST ABOUT RELIABILITY

Mustercall asks for the Alarms & reminders permission so that your alarm is exact, and it shows its own protection status on Home. If the exact alarm or the full-screen alarm is switched off on your phone, it tells you and takes you straight to the setting. If exact alarms are not allowed, Mustercall still arms — but Android may then deliver the alarm a few minutes late, and it says so rather than pretending.

WHAT IT IS NOT

Mustercall is not an emergency service. It does not call 999, and it cannot reach anyone if your phone is off, has no signal or is out of battery. If you are in danger, call the emergency services.
