Mustercall

A scheduled check-in for people who work alone. Arm a session, check in when it pings — and if you miss one, the person you nominated is told automatically.

Not an emergency service

Mustercall does not contact the emergency services. In an emergency, call your local emergency number (999 in the UK).

Private by structure

Your history lives on your phone. Your contact's email leaves it only inside an escalation, through a function that stores nothing. No account, no analytics, no ads.
