Best free running form analysis apps and what free gets you
Six free ways to check your running form in 2026, what each free tier actually includes, and how to avoid the free trials that charge you anyway.
Free running form analysis exists, but every free option is capped in some way: a fixed number of analyses, a desktop-only tool, or your own eyes doing the reading. The six options below are the ones that are genuinely free to start, with the limit named for each.

Read this before you tap "start free trial"
One of the loudest complaint clusters in the reviews we pulled is not accuracy. It is billing. Across the running and video analysis apps we checked, 95 negative reviews described a trial that charged them.
A 1 star Google Play review of Ochy: "DO NOT take the yearly plan which claims to include a 7 day free trial because they will take all your money upfront and when you cancel within the time you won't get any refund."
A 1 star Google Play review of myDartfish Express: "This is NOT a trial version. It wants your credit card info and forces you to sign a contract to pay fees if you do not remember to cancel in 15 days."
Free and free trial are different things. Free means a result without entering a card. A free trial means you enter a card and a timer starts.
1. Movaia free tier
Best for: the most free AI analyses per month.
Movaia is a web app with no store listing. You upload a clip in a browser and wait. The vendor says around 5 minutes for a normal-speed video and up to 30 minutes with slow motion and rear view.
Pros:
- The free tier gives 2 limited analyses a month, per the vendor site. That is more free output than any rival here.
- Nothing to install, so it works from a laptop.
Cons:
- The vendor calls the free analyses limited. The full report, rear view and exercises sit in Pro, listed at the time of writing as US$2.50 a month billed yearly at US$29.94.
- You upload the whole video to a server and wait minutes.
- No store listing, so no user reviews to check.
Who it is for: a runner who wants two free looks a month and does not mind a browser.
2. Ochy's one free analysis
Best for: one detailed AI report at no cost.
Ochy is the most reviewed app in this category. Its free tier is one analysis. A Google Play reviewer: "Yes, it offers A SINGLE analysis to free users. JUST 1."
Pros:
- The widest metric set of any consumer app here, including cadence and overstride.
- One analysis is enough to see whether you like the output.
Cons:
- One is one. There is no second free look, so no free before and after.
- Reviewers report a countdown discount popup before the first analysis. A 1 star Google Play review: "Very greedy developor, offering discounts at premium plans for a limited time."
- Price is hard to find up front. A 1 star AU review: "They won't show pricing in the App Store, or on their website."
Price at the time of writing, as listed in the App Store: $19.99 a month, $89.99 to $119.99 a year, or $49.99 for 15 analyses.
Who it is for: a runner who wants one rich report and will decide after seeing it.
3. Caden
Best for: a first look that comes with a fix.
Caden is an iPhone app. You film 5 to 20 seconds from the side, outdoors or on a treadmill. The audio is removed and the clip uploads to private storage under your account, where Caden's servers run the pose estimation. The download is free and the price is shown before any subscription. The full analysis, the practice plan and the before and after comparison need Pro.
Pros:
- Free to download, no card needed to start.
- The result includes the frame your verdict came from, so you can check it with your own eyes.
- Caden rejects a clip it cannot read instead of guessing.
Cons:
- The full analysis, plan and comparison need Pro.
- iPhone only, iOS 17 or later. No Android.
- No public ratings yet, so you cannot check other people's experience.
Who it is for: an iPhone runner who wants to see the fault before paying anything.
4. Kinovea
Best for: measuring angles yourself, for free, forever.
Kinovea is free open-source video analysis software for Windows desktop. You load a clip, step through frames and draw angles by hand. It is the standard free answer for people who lost Coach's Eye.
Pros:
- Free with no tier, no account and no upload.
- Precise manual tools. You choose the frame and the landmarks.
Cons:
- Windows desktop only. A third-party guide notes: "There is no mobile port of Kinovea, and none is planned."
- Stability complaints on its own forum, including "Crash of Kinovea every 2 or 3 actions".
- No verdict and no drills. It measures. You interpret.
Who it is for: a coach or a patient nerd with a Windows machine. See Kinovea alternative for iPhone.
5. Your own Photos app
Best for: free, right now, with no account.
Film yourself in slow motion, open the clip in Photos and drag along the timeline until the foot lands. Most phones shoot 120 or 240 frames per second, which is enough to see foot strike.
Pros:
- Completely free and completely private.
- No app can take your video away or lock it behind a renewal.
Cons:
- No numbers. You cannot measure landing reach or lean angle by eye.
- You need to know what to look for. Read what does overstriding look like first.
Who it is for: anyone deciding whether form work is worth paying for.
6. A free shoe shop gait check
Best for: picking a shoe, not fixing your form.
Many running shops film a short treadmill clip and watch it back with you, usually to suggest a shoe category based on pronation. It is free with a fitting.
Pros:
- Free, in person, and a human answers your questions.
- Pronation is one thing a 2D app cannot judge well, and a shop sees it on a treadmill.
Cons:
- It is built around a shoe sale, not a form plan.
- No cadence, no landing reach, no drills and no follow-up.
Who it is for: a runner buying shoes who also wants a glance at their stride.
How we ranked
- Works from a normal phone video. Kinovea loses points because it needs a desktop.
- Shows the frame where the fault happens. Your Photos app does this by definition. Caden does it in the app.
- Gives drills, not just a score. Only the paid tiers do this, which is the honest trade.
- Honest about limits. No 2D video, free or paid, measures force or pronation well.
- Price and billing clarity. Anything that needs a card before you see a result ranks below anything that does not.
- Review sentiment, weighted by volume. Caden has none yet.

- Choose Side view, prop the phone at hip height and film 10 to 20 seconds at easy pace.
- Read the form score and the six dials on your free analysis.
- Open Breakpoints and look at the Foot strike frame. Check the verdict against what you see.
- If the result matches, start a 4 or 8 week plan on the Exercises tab.
- Re-film in week 4 and compare in Before and after under Stats.
FAQ
Is there a completely free running form analysis app?
Not one with a full report and no cap. Movaia gives 2 limited analyses a month and Ochy gives one. Caden is free to download and shows its price before you subscribe. After that every option here charges.
Can I analyse my running form without any app?
Yes. Film yourself in slow motion and scrub the video frame by frame in your Photos app. You get the picture but no measurements. See free running form analysis.
How do I avoid being charged after a free trial?
Prefer tools that show a result before asking for a card. If you start a trial, cancel in your App Store or Google Play subscription settings, not in the app.
Do free gait checks at running shops help my form?
They help you buy shoes. They rarely cover cadence, landing reach or arm swing, and there is no follow-up check.
