Live 10 years longer.
Using the habits research shows add years.
How can I estimate and extend my lifespan?
It depends on which factors matter most for you. Sleep, exercise, diet, smoking, alcohol, and blood pressure each shift life expectancy differently. A free quiz can estimate your lifespan and biological age in about 5 minutes, then show which habit would add the most years. YapSpan uses published study figures—not invented numbers—so you can see exactly where each estimate comes from.

Kind words from early users
A few things people have told us after trying YapSpan.
Such a good approach. Too many people want to continue to optimize where they're already quite strong (ie, diet) while ignoring a huge gap that's present (ie, feeling like you have no one to call in an emergency)
“You had me at Dementia! 😂 I have to find a sauna near me!”
Priya “Sucha SMART app you've created! BRAVO! 👏👏👏”
Iris “This is brilliant stuff”
Hannah “Wow that looks great 👍”
Sam “10 squats every hour, is the easiest sitting-counter”
