Biomechanical analysis
in 3D, from a smartphone.
Ten seconds of video filmed in the field, a musculoskeletal model rebuilt in three dimensions, and every metric placed against its published norm. No markers or sensors, in one to three minutes.

Film, rebuild, compare.
01 · Capture
Ten seconds of video, wherever the athlete trains.
- On a smartphone, on site
Filmed from the app, on the road, the track or the court. No cameras to set up, no lab required.
- Markerless
Nothing to attach or calibrate between athletes: a whole team gets through in the time a conventional setup takes.
- One to three minutes
One minute for a side-view analysis, three for the full three-dimensional reconstruction.
02 · The model
A reconstructed skeleton, not a silhouette.
- Musculoskeletal
The points detected in the video are linked to an anatomical model: you see the joints themselves, constrained to what is physiologically possible.
- Added depth
Beyond flexion seen from the side, internal and external knee rotation, which a single plane cannot show. 43 angles, left and right.
- Across the whole cycle
Every angle tracked over time, with its minimum, maximum, range and value at top and bottom dead centre.
03 · The norms
Every metric placed against its norm.
- Published references
Each norm comes from a publication cited under the metric, adjusted to the sport and the level: recreational, trained, elite.
- Left and right
Every metric compared between both sides, across the whole movement.
- Over time
Two recordings several weeks apart, to objectively show what has changed after an adjustment or a return from injury.
What a goniometer or markers cannot measure.
A goniometer measures a static angle in a single plane, and readings vary by several degrees from one examiner to another. Marker-based systems are accurate, but they require a lab and setup time for each athlete, and their markers slide with the skin.
In the field
Measurement happens where the athlete trains and competes, in the position they actually hold, rather than on a turbo trainer during a one-off setup.
Markerless
Nothing stuck to the skin, so no skin sliding, the known weakness of markers on athletes with more soft tissue.
In three dimensions
Beyond the sagittal plane: knee rotation, pelvic tilt, trunk sway. 43 angles measured on the left and right.
Accuracy is currently being validated. We are comparing our measurements with a marker-based optoelectronic system, the laboratory reference. Early results show a difference of under three degrees on joint angles; the figure is still to be confirmed by the full study.
Cycling first, and well beyond.
The same engines process every movement. A new sport is a protocol to write, not a technology to invent.
Road · TT · comfort
Cycling
Bikefit on an indoor trainer or analysis during a race, filmed from a motorbike or a support vehicle, with reference values specific to each position.
Stride · cadence
Running
The stride cycle analysed from the side and in three dimensions, left and right.
Sprint · jump · squat
Athletics
Start and acceleration, countermovement jump, squat: depth, alignment and compensations.
Custom protocol
Tennis
Serve and groundstrokes: the protocol is built with you on the existing engines, and each movement is validated before it is offered.
For the people who support performance.
Cycling teams
The whole squad filmed on a ride or at a training camp, processed afterwards in batch, and followed from one season to the next.
Federations and development centres
A shared protocol to compare athletes with each other and over time, using your own reference values.
Athletics and tennis clubs
Field measurement within reach of coaching staff, with no lab required.
Bike fitters, sports physios, strength coaches
Objective measurement and reference values to support your adjustments. The decision remains yours.
