Kinalyse

Measure movement from video you already have

Kinalyse turns an ordinary clip into numbers you can defend — jump height, bar path, contact time, joint angles — and tells you how each one was obtained.

What it does Support

Guided tests

Countermovement and squat jumps, drop jump and RSI, weightlifting and barbell bar path, five-times sit-to-stand, 30-second chair stand. Each walks through camera setup, calibration, quality checks and results.

Every number labelled

Results carry a badge saying how they were obtained — directly measured, calibrated, model-derived, or estimated. An estimate is presented as an indicator, not a laboratory value.

Methods you can check

Reports include the formula behind each metric, what every symbol means, and the assumptions it is only true under — because that is usually where the error lives.

Change you can believe

A comparison against a previous session judges the difference against that athlete’s own trial-to-trial variation, rather than presenting any change as improvement.

Tracking and pose

Point and angle tracking with manual correction, pose overlay, filtering for kinematic data, and side-by-side comparison of two clips with synchronised playback.

Lab data too

Import C3D motion capture and force-plate files. Plot, filter and export them alongside results measured from video.

What Kinalyse is not

Kinalyse measures sports performance. It does not diagnose, does not screen for injury risk, makes no medical claim, and is not a medical device.

The citations in the app establish that a published method can be valid, in the population and conditions its paper studied. They do not validate this software — that would need its own study. Treat the numbers as a capable instrument’s rather than a laboratory’s: well suited to tracking change in one athlete over time, less suited to being quoted as absolute values.

Your data stays on your Mac

No account, no sign-in, no cloud, no analytics. Athletes, clips, results and reports live in a folder belonging to Kinalyse alone. Read the privacy policy — it is short, and it is checked against the source code.
