The platform
Two tools,
one deliberate system.
Real-Time Analysis
Point. Run.
Results in seconds.
Open the app, point your camera, run. Biomechanical feedback lands before you catch your breath — cadence, ground contact time, pelvic drop, and stride symmetry scored against an elite baseline in real time.
01
Live joint tracking
MediaPipe Pose maps 33 landmarks frame-by-frame as you run. No upload, no wait.
02
Instant elite scoring
Eight metrics benchmarked against an elite model the moment your run ends.
03
Week-over-week delta
Stack analyses across sessions. See exactly what shifts after a cue or drill block.
How it works
Four steps.
Zero wearables.
01
Tell us your goal.
Race distance, target time, starting fitness, weekly availability. Two minutes of onboarding.
02
Get your plan.
A training block sequence appears in your calendar. Tempo days, long runs, rest days — all sequenced by the AI.
03
Live treadmill sessions, science-backed scores.
Film yourself running live on the treadmill. The app analyses your form in real time against the latest biomechanical research — building a session record that shows exactly how your mechanics evolve.
04
The plan adapts.
If your form breaks down under fatigue, next week gets more technique work. If cadence is locked in, we push volume.
Biomechanics lab
Eight metrics. One clip. No lab.
Velocity uses MediaPipe Pose to extract 2D sagittal kinematics from a single phone clip. We score each metric against an elite-runner reference model, then surface the two that'll move your times most.
