Most timers you tap to start and tap to stop. However, if you are intently focused on something else, your response time to stop the timer may be slow, or you may miss it altogether.
The Dead Man's Timer will start counting on a touch, then conclude when the touch is finished.
The usecase I envision is balance exercises where I want to time the duration I can remain balanced, and track my progress (Monday: 30.2 seconds, Tuesday 39.8 seconds, etc). However, when you lose your balance, your priority is to stop yourself from falling, not to stop your phone timer
