Your phone has been measuring your health for years.
You just haven't seen it yet.
Your phone's motion sensors silently capture how fast you walk, how symmetrically you step, how consistently your stride holds. Gait Signature makes that data visible, as a signature that's uniquely yours, changing over time.
No wearable required · Free at launch
Doctors have known this for 15 years.
Your phone has been measuring it for 5.
Gait Signature shows you the connection.
Gait speed predicts survival more accurately than blood pressure, BMI, or cholesterol. Your phone's motion sensors have been silently capturing your walking speed, stride length, step symmetry, and balance, multiple times a day, since you first carried it. That data has never been shown to you.
Clinically validated
Gait speed is the sixth vital sign, validated in a 34,000-person JAMA meta-analysis.
Already in your pocket
Your phone’s motion sensors generate 3–8 gait samples daily, no action required.
Never been connected
Gait Signature is the first product to make this signal visible, longitudinally, to you.
A signature, not a score.
Gait Signature creates two longitudinal health signatures from sensors already in your phone.
Movement IQ
Six dimensions of how you move
Cognitive IQ
Six dimensions of how you process
Movement IQ
pace · symmetry · stride · steadiness · flow · confidence
The twelve dimensions combine into your Gait Signature, a radar unique to you, changing over time. The trajectory is the signal.
You've already been doing it.
Gait Signature is passive by design. The monthly check-in is the only thing we ever ask you to do deliberately.
Passive collection
Your phone’s motion sensors deliver 3–8 validated gait measurements to Gait Signature daily. You carry your phone. That’s it.
Overnight processing
Each night your day’s data is processed and your Movement IQ updates. No battery drain, no action required.
Monthly check-in
Once a month, a 3-minute guided walk and brief cognitive battery anchors your passive data to a controlled baseline.
Your signature has been forming for years. Gait Signature makes it visible.
No wearable · No blood draw · No clinic visit
Every claim is a citation.
Gait Signature measures what researchers have validated in peer-reviewed studies. The links below go to PubMed. We encourage you to check them.
In a 34,485-person meta-analysis, 10-year survival ranged from 19% to 87% based on walking speed at age 75, stronger than most clinical biomarkers.
Studenski et al., JAMA 2011, PMID 21205966Adults with simultaneous decline in gait speed and memory faced 24.7 times the dementia risk of those with neither decline.
Callisaya et al., JAMA Network Open 2022, PMID 35639376Gait changes are detectable 7 to 10 years before a clinical dementia diagnosis, making longitudinal gait tracking a meaningful early signal.
Dumurgier et al., J Alzheimers Dis 2017, PMID 27302701Passive typing pattern analysis achieved 97.9% sensitivity and 96.9% specificity in distinguishing MCI from healthy controls.
JMIR 2024, PMID 39475819Habitual brisk walkers had telomere lengths equivalent to people 16 years younger than their chronological age.
Hamer & Stamatakis, Communications Biology 2022Gait Signature does not diagnose, treat, or predict any medical condition. Citations reflect findings by independent researchers in controlled studies.
They measure what's in your body.
Gait Signature measures what it can do.
Every longevity tool in your stack measures inputs. Gait Signature measures outputs, how your body and brain actually perform.
Biomarkers at a moment in time. Comprehensive, expensive, and tells you what’s in your blood.
Heart rate, sleep, recovery. Excellent hardware worn continuously on your body.
Isolated cognitive exercises with gamified engagement. Trains specific mental tasks.
Both movement and cognitive signatures. Passive and active. Longitudinal. From the phone you already own.
Built on peer-reviewed science. Building the team to take it further.
Grounded in published research
Every metric in Gait Signature traces back to peer-reviewed literature indexed on PubMed. We did not invent the science, we are making it accessible. As our understanding deepens, so will the product.
Research & Advisory, actively recruiting
We are building an advisory board of researchers in gerontology, neuromotor science, and cognitive aging. If you work in gait analysis, functional longevity, or digital biomarkers, we would love to talk.
hello@gaitsignature.comHow we handle your data
Your gait and cognitive data is uploaded to our servers for processing, research, and anonymised population-level analysis. You can request deletion of your personal data at any time, though anonymised aggregations that have already been generated may persist.
Gait Signature is not a medical device and does not diagnose any medical condition. It is a general wellness tool for tracking functional performance over time.
Your signature has been forming for years.
You just haven't been able to see it.
Now you can.
Gait Signature is free to download. Your Movement IQ begins forming from day one, reading gait data your phone has already been collecting. The monthly check-in takes three minutes.
