Your phone's motion sensors have been quietly capturing how you walk for years: how fast you move, how symmetrically you step, how consistently your stride holds. Gait Signature makes that data visible as a signature that's uniquely yours and changes over time.

No wearable. No blood draw. No clinic visit. Just the phone you already carry.

WHAT IT MEASURES

Gait Signature builds two longitudinal signatures from sensors already in your phone.
Your Movement Signature tracks six dimensions of how you move:

- Pace: normalized walking speed
- Symmetry: left/right step balance
- Stride: step length relative to height
- Steadiness: stride-to-stride consistency
- Flow: swing-to-stance movement quality
- Confidence: composite dynamic balance

Your Cognitive Signature tracks six dimensions of how you process:

- Reaction: tap latency and processing speed
- Fluency: typing dynamics and cognitive flow
- Precision: touch accuracy and coordination
- Stability: fine motor control via motion sensing
- Memory: working memory via a monthly recall check
- Clarity: psychomotor clarity via a typing check

Together these twelve dimensions form your Gait Signature: a picture unique to you that shifts as you do. The trajectory is the signal.

HOW IT WORKS

Gait Signature is passive by design.

Passive collection. Your phone's motion sensors deliver several validated gait measurements each day. You carry your phone. That's it.

Overnight processing. Each night your data is processed and your signature updates. No battery drain, no action required.

Monthly check-in. Once a month, a three-minute guided walk and brief cognitive check anchor your passive data to a controlled baseline.

Your signature has been forming for years. Gait Signature makes it visible.

GROUNDED IN PUBLISHED RESEARCH

Every dimension traces back to peer-reviewed literature indexed on PubMed. We didn't invent the science; we're making it accessible. Gait speed has been described in research as a sixth vital sign, studied in large adult populations. As the research deepens, so will the product.

WHY GAIT SIGNATURE

Most longevity tools measure inputs: what's in your blood, your heart rate, your sleep. Gait Signature measures outputs, how your body and brain actually perform, from the phone you already own. No hardware to buy. No subscription required to start.

YOUR DATA

Your movement and cognitive data is uploaded to our servers to generate your signature and to support research through anonymized, aggregated analysis. We don't sell your personal data and we don't share it with third parties for their advertising. You can request deletion of your personal data at any time.
