Deadman Check-in: solo safety timer

Periodic check-ins that alert emergency contacts if you miss one

Problem

When hiking a volcano alone, if you get hurt nobody knows where you are or what you were doing; existing safety apps are either too heavy or require constant background location, unfit for lightweight scenarios.

Solution

Users set a check-in interval (hourly/daily/weekly) and tap to check in; if they miss it, prewritten messages with location and activity details go to chosen contacts, with optional escalation.

Users

Solo outdoor adventurers, elderly living alone, solo business travelers

MVP

Set interval and contacts; one-tap check-in; missed check-in triggers email/SMS alerts; include last location and activity note

Revenue

Subscription ($3-5/mo) with SMS credits; free tier email-only

Why now

Solo outdoor and solo-living safety awareness is rising; incumbents are heavy or hardware-dependent; indie can ship an MVP quickly
