A deathclock with a wagging tail
See your span. Then stretch it.
A five-minute life quiz turns how you sleep, move, and eat into a biological age and a life expectancy you can actually change, one habit and one year at a time.

Why it works
Memento mori, minus the dread.
YapSpan makes the biggest number in your life visible, then breaks it into habits small enough to fix this week.
A quiz, not a lecture
Five minutes of honest questions become two numbers: your biological age and your estimated span. Retake it any time. The model is deterministic, so the only thing that moves the number is you.
Every habit has a price tag in years
Sleep, exercise, diet, stress: sixteen markers, each scored 0 to 100 with the years it adds or subtracts. Fix the cheapest one first and watch your span stretch.
Quizzes you’ll actually retake
Every marker has its own quick check. Retake any of them whenever life changes and watch your span move. The life quiz runs right here on the web too — no download needed.
How it works
Three taps to a longer runway
Take the life quiz
Five minutes, honest answers, no wearables required. Retake it whenever you want a fresh read.
Meet your numbers
Biological age next to your birthday age. If you opt in, you also see the date the clock is counting down to.
Stretch your span
Each marker shows what it costs you and how to earn it back. Retake checks, and your history charts the years you reclaim.
The death age is opt-in. Some people want the date; some never do. You choose, confirm it on purpose, and can turn it off any time.
The levers
Sixteen markers. Each one worth years.
Every marker gets a 0–100 score and shows the years it adds or subtracts, so you always know which habit pays best next.
Every marker has its own two-minute check — browse all the quizzes.

Early words
People are stretching.
I took it as a joke at a birthday party. Then it told me my sleep was costing me years, and now I have a bedtime like a well-raised adult.

Beta tester
Turning on the death age was the scariest tap of my week. Watching the estimate move the right way a month later was the best one.
The Opt-In Optimist
Beta tester
The marker quizzes are two minutes each. I fixed the cheapest one first, retook it, and watched my span actually move. Addictive.
