This is what the check produces.
No bloodwork and no wearable needed. Twelve questions about how you live, and a number you can act on today.
Sleep, movement, food, drink, stress, people. Answer as things really are — it takes a minute.
Your current path and your potential path, drawn side by side — with the years between them.
The handful of habits that move your number most — ranked by the years each one adds back.
That's day one. Here is what membership does after that.
Ticked in seconds. Small on purpose — the point is a week you can repeat.
Log your day in under a minute. Your estimate moves with what you record.
You answer the questions again and both trajectories are recalculated from your new answers.
Food, then movement, then sleep — ordered by the years each one adds, until the gap is closed.
One trajectory and the few habits that move it most, ranked, so you always know what to do next.
Most of how you age is built from daily choices, not genetics. We turn decades of published research into one number you can act on — and we show our work.
Built on 25+ published studies in longevity and lifestyle research — every source is yours to read.
Every assumption in the model is written down, and you can read all of them.
Every number comes with a range, because the underlying research has uncertainty in it.
Encrypted, never sold, and deletable from your Account page, after typing DELETE to confirm. You don't even need an account to see your number.
Daily habits explain a large share of the difference in healthy lifespan between people in long-term cohort studies.
These habits show the largest effects in the research. The check tells you which ones apply to you, and how many years each is worth.
Moving from short or broken sleep to a steady 7–8 hours is one of the largest single changes in the model.
Brisk walking counts. Regular movement has the largest effect size of any habit in the model, and it costs nothing.
Less ultra-processed food, more plants. Swaps rather than a diet.
Ranges shown are illustrative spans from the published research the model is built on — your own numbers depend on where you're starting from. That's exactly what the check works out.
