How well you move and think, measured over time
Your phone can measure how well you move and think.
No wearable. No blood draw. No clinic. A short walk and a couple of minutes of sitting turn the sensors you already carry into a picture of how you move and think — compared with people your age, and tracked over time.

What it measures
Twelve dimensions, across movement and thinking.
Most health measurement looks at inputs — what’s in your blood, how you slept. footing measures output: what your body and mind can actually do, and whether that’s holding, improving, or slipping.
Mobility
Six dimensions- Pace
How fast you walk.
- Stride
How long your steps are.
- Cadence
How many steps you take a minute.
- Steadiness
How alike your steps are, one to the next.
- Regularity
How evenly your stride repeats.
- Turn
How long you take to turn around.
Cognitive
Six dimensions- Reaction
How quickly you respond.
- Precision
How often you get it right.
- Attention
How steady your focus stays from one answer to the next.
- Memory
How long a sequence you can hold in mind.
- Timing
How steady a rhythm you can keep.
- Fluency
How quickly you type a short phrase.
How it works
Three beats. Then it just keeps going.
Take a walk
Put the phone in your pocket and walk the way you normally walk. That’s the measurement — no treadmill, no lab, nothing to strap on.
About three minutesSit down for two minutes
A short set of tap-and-recall tasks. Movement alone can’t tell you how you’re thinking, so we ask for both before we tell you anything.
About two minutesSee where you stand
From your very first walk, see how each part of how you move compares with people your age. After a few walks, your readings become a Mobility Age and a Cognitive Age — and you can watch them over time.
Then check back every few daysOne reading is a starting point. The trajectory is the actual signal — which is why footing is built to be opened for years, not finished in a week.
The evidence
At 45, the slowest walkers had been aging five years faster.
5.0 years
In a New Zealand birth cohort followed for five decades, 904 adults had their walking measured at age 45. Those in the slowest fifth had been aging — across nineteen biomarkers spanning multiple organ systems — about five years faster since their twenties than those in the fastest fifth.

What it costs
The measurement is free. Forever.
Every dimension we measure, your Mobility Age and Cognitive Age, and your full history — free, with no trial clock on them. Later, we'll offer optional programs built on the same measurement.
The rules we build by
Published, so you can hold us to them.
- A number never appears without context.
An age with no explanation isn't information, it's anxiety. Every number in footing arrives with what it means and what to do next.
- No fear marketing.
Falls and dementia research is why we’re rigorous — it is not a scare tactic, and we won’t use it as one.
- No woo.
No frequencies, no energy, no destiny. Every claim we make points at a study you can go read.
- Never a leaderboard.
Comparison is opt-in and private. Your measurement is yours, and nobody else sees it unless you decide to show them.
See where you stand.
You don’t get one measurement of how you’re aging. You get a line — and a line can be changed.
