AI-powered running form analysis
See your form, then fix it.
Send a short side-on clip. The AI breaks it into cadence, lean, foot strike, and L/R symmetry, with a one-line read on each item. You leave with a concrete list of what to work on.
Phone footage is fine. Results in under 2 minutes. New accounts get 3 free analyses to try.
Why look at your form
Adding mileage doesn't change how you move. A single video, reviewed carefully, surfaces specific issues that years of training rarely will.
Catch injury patterns early
Overstriding, hip drop, and knee valgus are well-known precursors to shin splints, ITB syndrome, and runner's knee. The goal is to notice them before symptoms appear.
Run easier at the same effort
A 5° change in trunk lean or a 10-spm cadence shift can be worth 15–30 seconds per km at the same heart rate. Small adjustments compound over a marathon.
Break sprint mechanics into parts
Knee drive, hip extension, and arm carriage are each scored against reference ranges, so it's clear which element is holding the rest back.
Track in numbers, not feel
An hour with a running coach runs S$80–200. RunRank measures the same items in seconds and stores them for month-to-month comparison.
Included in every analysis
Every clip runs through the same pipeline, so the output is consistent across uploads.
- AI form scorecardSeven focus areas — cadence, lean, knee drive, stride, foot strike, vertical oscillation, arms — graded good / needs work / OK / unclear, each with a one-sentence note.
- Skeleton overlayA 33-point pose skeleton drawn over the original video. Step through frame by frame to inspect each phase of the gait cycle.
- Objective metricsCadence (spm), stride length, vertical oscillation, ground contact time, and trunk lean angle — measured to ±10 ms / 0.5 cm precision.
- Drill recommendationsA-skips, strides, metronome runs, plank progressions — exercises matched to the specific findings in your clip.
- Left / right strike comparisonSide-by-side stride-cycle clips for left and right contact, with a step mode for inspecting the contact instant.
- Shareable result pageEach analysis has its own URL. Send the link to a coach, training partner, or physiotherapist for a second look.
