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 two minutes of sitting turn the sensors you already carry into a longitudinal measure of how you’re aging — and one clear thing to do about it.

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.

Movement

Six dimensions
  • Pace

    Walking speed, normalized for your height and age.

  • Symmetry

    How evenly your left and right steps match each other.

  • Stride

    Step length relative to your height.

  • Steadiness

    How consistent one stride is with the next.

  • Flow

    The rhythm between swing and stance — movement quality.

  • Confidence

    Dynamic balance while you’re actually in motion.

Cognition

Six dimensions
  • Reaction

    How quickly you respond — processing speed.

  • Fluency

    The evenness of your rhythm on a short tapping task.

  • Precision

    Accuracy of fine, targeted movement.

  • Stability

    Steadiness of fine motor control.

  • Memory

    Working memory, from a brief sequence recall.

  • Clarity

    Sharpness and consistency under a short timed task.

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 minutes

Sit 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 minutes

See where you stand

The two combine into a Reading, and your Reading becomes an Age — plus one specific, doable thing that tends to move it.

Then check back every few days

One 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.

Your twelve dimensions, your Age, your trend, and one real next step — free, permanently, with no trial clock on them. What you can pay for is interpretation: a program that adapts as you change, a deeper cognitive battery, and how you compare with people your age.

We’ll publish subscription pricing when it’s settled. We’d rather say nothing than say a number we then change.

The rules we build by

Published, so you can hold us to them.

  • A number never appears without something to do about it.

    An age you can’t act on isn’t information, it’s anxiety. Every number in footing arrives beside a next step.

  • 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.

Find your footing.

You don’t get one measurement of how you’re aging. You get a line — and a line can be changed.
