Record a short clip of yourself running. RunGait runs the gait analysis and spots the left/right imbalances slowing you down, and turns them into a strength plan you can actually train.
Prop your phone at the end of a hallway, path, or treadmill. RunGait handles the rest, it even figures out which angle each clip was shot from.

Run toward the camera, away, and past the side, or drop in clips you already have. RunGait auto-detects each view, so there's nothing to label.
Apple Vision extracts your body pose frame by frame. Our engine segments each gait cycle, measures frontal- and sagittal-plane motion, and scores left-vs-right asymmetry, the heavy processing happens right on your iPhone.
Your report
Your snapshot
See five movement-quality scores, ranked findings with a plain-English "why it matters," and a personalized 4-week strength block. Retest in four weeks to track the change.
RunGait reports left-vs-right patterns, never absolute joint angles, because single-camera 2D angles carry real error. Every finding ships with a confidence badge, and weak signals are gated out.
Knee drifting toward the midline under load.
Not enough push behind you at the end of stance.
Hip dropping on the opposite side during single-leg stance.
Spending longer on one leg than the other.
Foot landing too far ahead of your center of mass.
Torso tipping to one side through the stride.
Thresholds and muscle mappings are grounded in running-biomechanics literature. Frontal-plane signs are surfaced at lower confidence by design.
When a stride falls apart, the running world tends to reach for a new shoe or a custom orthotic. Those prop up the movement from the outside. They rarely change why it broke down. More often the cause is further up the chain, a muscle that isn’t holding its end of the stride.
The part you can see fail, the foot rolling in, the arch flattening, is usually the end of the story. A hip that can’t stabilize lets the knee drift toward the midline, and that drift shows up as pronation down at the foot.
Support the foot and you’ve treated the last link in the chain while the first one, the strength that never showed up, stays exactly as weak as it was. That’s why the fix so often feels temporary: the moment the prop comes off, the collapse comes back.
RunGait reads where in the chain the breakdown starts, then points your strength work there.

What the research actually shows
In randomized trials, softer or more cushioned midsoles have not reliably lowered running-injury rates.
For runners without a diagnosed foot pathology, prescriptive orthotics show inconsistent, often temporary effects.
Pooled randomized trials found progressive strength training cut overuse injuries by roughly half.
None of this makes shoes the enemy, run in what feels good. It means the durable fix is building the capacity you’re missing, not renting it from a midsole. RunGait is a screening tool, not medical advice; real pain deserves a qualified professional.
RunGait is deliberately careful about what it claims. It won't coach your form or sell you shoes, it surfaces likely strength gaps as training hypotheses you can test.
RunGait doesn't tell you to "fix your form." It maps every finding to the specific muscles behind it and prescribes the strength work that targets them. Retest in a few weeks and watch the asymmetry shrink.
The app is free to use for as long as you like, and your gait score never costs anything. A subscription is what turns a score into the strength work behind it.

No. Just an iPhone and about ten meters to run, a hallway, path, or treadmill. Prop the phone at one end. No wearables, force plates, or lab required.
Prop your iPhone at one end of a flat ten-meter stretch, then run toward the camera, away from it, and past the side. RunGait detects each view automatically, analyzes your stride on-device, and returns movement-quality scores plus the specific strength work to address what it finds. No lab or wearables needed.
No. RunGait is a screening tool. It surfaces likely strength gaps as training hypotheses, each with a confidence score. It does not diagnose injuries or replace a clinician.
Absolute 2D joint angles from one camera carry roughly 5-15° of error, so RunGait does not report them. Instead it measures the difference between your left and right sides, which is far more reliable, and gates out signals too weak to trust.
It's tuned for runners, and the biomechanics rules reflect that. Walking clips work for capture too, but the strongest findings come from a natural running stride.
Five movement-quality scores (symmetry, hip control, knee control, push-off, trunk stability), a ranked list of findings with plain-English explanations, and a personalized 4-week strength block. Retest to track progress.
RunGait turns a short phone video of your run into five movement-quality scores and a strength plan built around what your stride is actually missing.
