See how you run. Then fix it.
Film a 5 to 20 second clip. Caden maps your stride, scores six parts of your form, freezes the frames that matter, and builds a practice plan around what it finds. No lab. No coach. No treadmill needed.
- Audio removed, clip kept private
- Side view, outdoors or on a treadmill
- Plan built from your own results
Most form apps tell you what is wrong. Caden tells you what to do about it.
We read over a thousand one and two star reviews of running form and video analysis apps. The same complaints came up again and again: the verdict looked wrong and there was no way to check it, the exercises were generic, the upload sat at zero percent, and the paywall came before the first analysis. Caden was built to answer those four.
- See the frame, not just the label. Every metric points at an annotated freeze frame so you can check the verdict with your own eyes.
- One cue per metric. Not a biomechanics lecture. A single thing to think about on your next run.
- A plan, not a PDF. Three short sessions a week for 4 or 8 weeks, built from your lowest scores and your time budget.
- Real progress, not a stuck bar. The upload shows each stage, and a failed run is removed instead of parked.
- Honest about limits. Caden rejects clips it cannot read instead of inventing a score.
- Try it before you pay. Download is free, and the price is on the screen before any purchase.
What you get after one clip
Four steps. About two minutes.

Set up the shot
Side view only: prop the phone sideways at hip height, or hand it to a friend. Works outdoors and on a treadmill.
- 2
Film or import a clip
5 to 20 seconds, running past at your normal easy pace with your whole body in frame. The framing guide shows you where to stand.
- 3
Read the score
The clip uploads with the audio removed and comes back as a form score out of 100, six metric dials, and annotated frames at foot strike, midstance and toe-off. Each metric has one cue and a plain-language note.

Follow the plan, re-film
Caden builds a 4 or 8 week plan from your lowest scores, three short sessions a week. At the end you film again and see the before and after side by side.

How to check your running form at home without a gait lab
A gait lab costs hundreds and needs a booking. A phone, a wall to lean it on and ten seconds of video will show you the five things that matter. Here is how.
How to fix running posture without overthinking it
Running posture comes down to torso lean and head position on a side-view video. How to see both, one cue, and posture exercises for 4 weeks.
How to stop bouncing when you run
Bouncing when running means your head rises and falls too much each step. A side video shows it. The cue is push back, not up. Four-week plan inside.
How to stop overstriding without slowing down
Overstriding means your foot lands ahead of your hip with a straight knee. Here is how to see it on video, the one cue that fixes it, and a 4-week drill plan.
How to track running form progress month to month
Most form apps give you one report and no way to compare. How to track running form progress: same view, same pace, same place, every four weeks.
Running form changes that often help knee pain
Overstriding, low cadence, a stiff landing and hip drop are often linked with knee pain in runners. Spot each on video and see what to change.
Running form analysis for your kind of runner
Running form analysis for marathon runners
Marathon running form breaks down late in the race, not early. Film yourself tired, see the drift on video and train the muscles that hold your shape.
Running form analysis on a treadmill
Treadmill running form analysis works with a phone at hip height beside the belt. Here is how to film it, what changes on a treadmill, and what Caden measures.
Running form app for beginners
Beginner running form is mostly about landing under your hip and not slumping. Film 15 seconds on your iPhone and Caden shows you what to fix first.
Running form app for runners with knee pain
Knee pain running form check from a phone clip. See if you reach forward or land stiff, which are often linked with runner's knee. Not a diagnosis.
Straight answers
Each answer links to a longer page if you want the detail.
How does Caden analyze my running form from a phone video?
You film a 5 to 20 second clip from the side, outdoors or on a treadmill. The app removes the audio and uploads the clip to your account, where pose estimation scores where your foot lands, knee bend on landing and at push-off, upper body lean, arm bend and head position. It also counts cadence in steps per minute.
Learn moreDo I need a treadmill or a gait lab?
No. Most people film outdoors on a flat path with a friend or a phone propped at hip height. Treadmill works too and is often easier to frame. A gait lab uses force plates and 3D markers, which Caden does not replace, but for form coaching a 2D side view catches the big issues.
Learn moreWhat is a good running form score?
Caden scores out of 100. 85 or above is excellent, 75 to 84 is good, 60 to 74 is fair, and below 60 needs work. The score is a coaching signal, not a medical grade, and it only compares like with like: same view, same direction, same analysis version, and a similar pace.
Learn moreHow do I know if I am overstriding?
Film from the side and freeze the frame at foot strike. If your ankle lands well ahead of your hip with a straight knee, you are overstriding. Caden marks this frame for you and measures the landing reach as a fraction of leg length.
Learn moreDoes Caden tell me how to fix what it finds, or just what is wrong?
Both. Each metric comes with one cue you can use on your next run, and the app builds a 4 or 8 week practice plan of drills, strength, balance and mobility sessions around your lowest scores. At the end you re-film and compare against your baseline.
Learn moreIs Caden accurate?
It measures 2D joint angles from video, so it is accurate for what a side view can see: landing reach, knee flexion, torso lean, arm angle and cadence. It cannot measure force or 3D rotation. Caden tells you when a clip is too dark, too far away or too short to trust, instead of guessing.
Learn moreHow is Caden different from Ochy?
Ochy is a lab-style biomechanics report used by coaches and clinics. Caden is a consumer coach. It keeps the report to six plain-language metrics, shows you the frames each verdict is based on, and turns the result into a plan you can follow that week.
Learn moreIs my video stored?
Yes, privately. The audio is removed, then the clip uploads to storage that only your account can reach. It stays there until you delete the analysis, which removes the clip, the frames and the measurements from our servers.

How do I know if I am overstriding?
You are overstriding if your foot lands well ahead of your hip with a straight knee. How to spot it on a side-view video and check it in a minute.
How does running form analysis work?
Running form analysis finds your joints in each frame, measures angles at foot strike, midstance and toe-off, and compares them to coaching ranges.
Is 180 cadence a myth?
The 180 steps per minute rule came from elite runners racing, not jogging. It is a floor for fast runners, not a target for you. What to aim for instead.
Is gait analysis worth it for runners?
Gait analysis is worth it when it shows you something you can act on. What each type gives you, who needs a clinic, and when a phone video is enough.
What angle should I film my running form from?
Film from the side first, square on, phone at hip height. Side view shows landing, knee bend, lean and arms. Front and behind add hip alignment.
What is a good running cadence?
A good running cadence lets your foot land under your hip at your normal pace. For most runners that is 165 to 180 at easy pace. Why 180 is a myth.

Gait analysis clinic vs app: which do you actually need?
