Lab-grade sprint analysis. No lab required.
Sprintalyze turns a smartphone video into a full biomechanical report in minutes. Ground contact times, joint angles, stride parameters, left–right asymmetry, and plain-language coaching insights. No markers, no hardware, no hours of post-processing.
Three steps from sprint to insight.
No markers. No markers' glue. No motion-capture suit. Just a smartphone video and a tripod.
Film
Point a smartphone at the sprinter. Record a single run at 120 fps from a tripod. No markers, no suit, no lighting setup.
Analyze
A top-down two-stage pipeline locates the athlete, then localises a sprint-optimised skeleton (full body plus heel, big toe, and small toe on each foot) with temporal smoothing tuned for ground-contact timing.
Understand
Get per-step metrics, whole-stride averages, left–right asymmetry flags, and automatic coaching cues written in plain training language.
Every number a sprint coach actually wants.
Not a wall of raw data. Structured metrics, per-step and per-zone, with the context needed to act on them.
Ground contact & flight times
Per step, accurate to the millisecond, with inner-contact zone averaging so you measure true top-speed, not the warm-up.
Joint angles
Hip, knee, and ankle across the full stride. Measured at the phases coaches actually care about: touchdown, mid-stance, toe-off.
Stride parameters
Step length, step frequency, and duty factor per athlete, per session, per zone. Tracked over time on athlete-level dashboards.
Center-of-mass trajectory
Vertical oscillation, horizontal displacement, and leg-stiffness proxy: the signals that distinguish efficient top-speed mechanics.
Left–right asymmetry
Flag contact-time, step-length, and joint-angle imbalances across sides. Spot hidden risk before it becomes an injury.
Automatic interpretation
Every metric gets a band, a plain-language interpretation, and where appropriate a short coaching cue. Never prescription, always insight.
From a sprint video to a readable answer.
Two screens from the app: the full-detail Results view for when you want the raw data, and the Top Speed Feedback view for when you want a verdict.
Severe overstriding. The foot is landing far ahead of the hip on every step.
Flight time is a bit outside the ideal window.
Measured where it matters. Beside the track.
The honest comparison. Lab systems are still the scientific gold standard; we aim to give you 90% of that depth at 0.1% of the cost and 10% of the friction.

Peer-reviewed models. Practitioner-grade engineering.
The pose-estimation research under Sprintalyze will be published and open, rooted in academic gait research. We sit on top of it. Carefully.
Markerless pose pipeline
A multi-stage markerless AI pipeline locates the athlete and extracts a sprint-tuned skeleton: body plus detailed foot landmarks. Optimised for the joints and contact points that actually drive sprint biomechanics.
Signal processing tuned for sprint
Temporal filtering and outlier rejection tuned for sprint kinematics remove detection noise while preserving the high-frequency content that matters for ground-contact timing.
Privacy by design
Videos are processed to extract the keypoint skeleton, then deleted. Only the extracted keypoints and the athlete metadata you create are stored. Infrastructure runs on EU servers. Delete any athlete, and all their data, in one tap.
Validation in progress
We're comparing Sprintalyze's measurements against marker-based gold-standard systems in partnership with sports-science labs. Results will be published here as studies complete.
We're happy to share validation methodology, keypoint schema, and signal-processing choices with sports scientists and research partners. Get in touch. We're building this openly.
Contact researchCoaches and scientists who want measured answers.
If you've ever said 'looked better today' and wished you had a number, you're the person we built this for.
- Cut the "I think we looked smoother today" loop. Get measured step-by-step numbers you can track across months.
- Top-speed mechanics, acceleration mechanics, asymmetry, in a format you can show the athlete on the spot.
- Screen entire rosters at the start of pre-season without a timing system or a lab.
- Identify players leaking energy at contact, and quantify the gap instead of calling it a 'feel'.
- Add a field-deployable markerless layer to your existing marker-based protocol.
- Access the raw keypoint data on request. We'll publish validation as studies complete.
The questions coaches ask first.
Early access. Priority seats.
We're onboarding a small group of coaches through summer 2026. Priority goes to sprint and S&C coaches working with competitive athletes. Leave your details and we'll be in touch before public launch.
