An app that predicts the day you'll die says it has tens of thousands of paying customers.
The idea: AI 'death clock' longevity app
Death Clock asks about your health and habits and predicts your death date, then coaches you to push it later. Founder Brent Franson told MediaPost it has 'well over a million downloads and tens of thousands of paying customers.' The provocative name did most of the marketing.

How to start your own
- Pick a provocative but responsible hook.
- Back it with real research and clear 'estimate' framing.
- Turn the shock moment into a habit-coaching product.
The catch
It's health-adjacent and emotionally loaded. Avoid fear-mongering.
