Shelf Life
In testing
A countdown to your statistically predicted last day.
What it is
Shelf Life turns a short quiz into a date: the day you are statistically predicted to die. Three questions give a first date. Eight optional lifestyle questions sharpen it, and the date moves as you answer.
The main screen is just the date and a live countdown. Home-screen and lock-screen widgets keep it in view, and a physical desk clock with red seven-segment digits is in development.
The prediction uses WHO life tables and lifestyle effects taken from named, published studies. It is a statistical estimate for reflection, not medical advice.
Why I built it
To be written Why I built Shelf Life. Two or three sentences in my own words.
Decisions along the way
A date after three questions
The first date appears after only three questions. The eight lifestyle questions are optional, and each answer visibly moves the date, so the extra effort pays for itself straight away.
One screen, one number
The main screen shows the date and the countdown and nothing else. Anything more would compete with the one thing the app is for.
Sources you can check
The baseline comes from WHO life tables, and every lifestyle adjustment comes from a named, published study. If the app is going to tell you something this blunt, it should show its working.
Nothing leaves your phone
There is no account and nothing is collected. The answers are personal, so they stay on the device.
