- The challenge
Gait is hard to measure in everyday practice
Watching a patient walk down the corridor gives an impression, not a measurement — and an impression cannot be compared with the impression from six months ago.
- The solution
A mobile app that reads every step
Accelerometer and gyroscope data from an ordinary phone is enough. The app records, finds each step, overlays the strides, compares with the previous visit and writes the findings up in plain clinical language.
- The impact
A quiet decline becomes visible early
Because every session lands on the patient's own timeline, a gradual change stands out long before it would be noticed by eye — and so does the effect of acting on it.
Walking is a vital sign
StepAnalyser turns a short walk into an objective gait report. A phone strapped to the patient's thigh records how the leg moves, the AI finds and measures every step, and the clinician gets a structured report to file, explain and compare at the next visit — with no lab, no markers and no treadmill.

A measurement that used to need a laboratory
How a person walks says a great deal about their health, and it changes long before anyone complains about it. But measuring gait properly has meant an instrumented lab: expensive, rare, and a referral away from the appointment where the change was first noticed.
StepAnalyser moves that measurement into the exam room. The patient walks a few metres with a phone on the thigh; the AI cleans the signal, marks every heel contact, lines the strides up and compares the walk against the patient's own baseline.
Inside the product

Measure, analyse, compare
A session moves through three screens. The clinician starts a measurement and the patient walks; the analysis shows the cleaned acceleration signal with every step marked; and the measurement list keeps each walk on the patient's own timeline.
That last screen is where the value is — a single walk is a snapshot, a series of them shows the trend.
What we built
- 01Gait analysis from smartphone sensorsAccelerometer and gyroscope data captures the walking pattern without markers, force plates or a treadmill.
- 02An AI report after every walkWalking rhythm, left/right balance and change since the last visit, summarised for clinicians rather than for engineers.
- 03Patient timelines and baselinesEach session is compared against the patient's own baseline, so slow change is visible across routine check-ups.
- 04Privacy by design, and exports for researchConsent is recorded before capture and identifiers are kept apart from the walking data; structured exports carry it into records and studies.
An objective gait assessment in your own exam room
StepAnalyser makes a measurement that used to require a gait lab part of an ordinary appointment — for preventive medicine, geriatrics, physiotherapy, neurology, sports medicine and orthopaedics.
The same work, as a service
- Mobile app developmentA business app is used standing up, in a hurry, sometimes with gloves on. So we design mobile apps for that first, build them for Android and iOS, and make sure they work without signal.Learn more
- Custom software developmentOff-the-shelf software asks you to adapt your process to it. We do the opposite: we understand how your company works, then build the system around that.Learn more
- Business softwareYou shouldn’t need two days and three spreadsheets to answer “how are we doing this week?”. We build the system that answers it as the work happens.Learn more
