Closed beta opening summer 2026

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.

How it works

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.

120 FPS OR MORE · SIDE VIEW · 1 TAKE

Analyze

Upload the clip and our sprint-tuned AI tracks the athlete's full body and feet, frame by frame. No markers, no manual work.

SPRINT-TUNED AI · FULL BODY + FEET

Understand

Get per-step metrics, whole-stride averages, left–right asymmetry flags, and automatic coaching cues written in plain training language.

PER-STEP · ZONE-AVERAGED · INTERPRETED

What you get

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.

92ms

avg GCT

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.

165°

peak knee drive

Joint angles

Hip, knee, and ankle across the full stride. Measured at the phases coaches actually care about: touchdown, mid-stance, toe-off.

4.42Hz

step frequency

Stride parameters

Step length, step frequency, and duty factor per athlete, per session, per zone. Tracked over time on athlete-level dashboards.

7.4cm

vertical osc.

Center-of-mass trajectory

Vertical oscillation, horizontal displacement, and leg-stiffness proxy: the signals that distinguish efficient top-speed mechanics.

±3.1%

GCT L/R delta

Left–right asymmetry

Flag contact-time, step-length, and joint-angle imbalances across sides. Spot hidden risk before it becomes an injury.

AUTO

coaching cues

Automatic interpretation

Every metric gets a band, a plain-language interpretation, and where appropriate a short coaching cue. Never prescription, always insight.

See it in action

From a sprint video to a readable answer.

Why Sprintalyze

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.

Pricing figures for other tools reflect publicly available information at time of writing. We'll keep this comparison current and publish validation data as studies complete.

Built on science

Serious science. Practitioner-grade engineering.

Rooted in established sprint-biomechanics and pose-estimation research, engineered into something you can actually use at the track.

Markerless motion capture

Ordinary smartphone video in, a precise full-body-and-feet skeleton out. No markers, no suit, no hardware.

Built for sprinting

Purpose-built for sprint speed and mechanics, not a generic body tracker repurposed for the track. Focused on the joints and contact points that drive performance.

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.

Who it's for

Coaches 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.

Sprint coach

Track & field clubs, federation programs, collegiate teams.

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.

S&C coach

Football, rugby, NFL, field sports, combine prep.

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'.

Sports scientist

Olympic training centers, university labs, performance diagnosticians.

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.
