I recently chanced upon this piece of news where a woman was trapped in her bathroom for days as her doorknob had somehow malfunctioned. She was living by herself at that point of time and didn’t think to bring her mobile along for her toilet trip when the misadventure happened.

As someone who is currently living by myself, this might very well be me, however low the chance might be. Is there any app that can track your last activity on your phone, and notify your next-of-kin should your last activity exceeds…say 24 hours?
