Runeasi alternatives: form analysis without a sensor
Runeasi is a belt sensor sold to physios. The honest alternatives for a form check without a clinic or hardware, and what each one can and cannot see.
Runeasi is not something you buy for yourself. It is a sensor on a lower-back belt plus software, sold to physios and clinics. If you want to check your running form without a clinic booking or a piece of hardware, the alternatives are a camera app on your phone, Caden, Ochy or Movaia, or a plain 2D video session with a physio. Be clear about the trade: the Runeasi sensor measures impact and left-right symmetry, and a camera cannot. A camera measures where your foot lands, how you lean, how your knees bend and how fast you turn over. Those are the things most runners actually want to fix.
What Runeasi does well
Runeasi is a spin-out from KU Leuven, a Belgian university with a strong sports science department. The product is a small sensor worn on a belt at the lower back, plus an app for the clinician. It gives a Running Quality score, measures impact loading and asymmetry between the two legs, and supports gait retraining with live cues. It is sold mainly to physios on 6, 12 or 24 month plans that include the hardware. The pricing page was not readable when we checked, so we have no price to give you.
Physios who use it rate it. On the r/physicaltherapy subreddit one wrote:
"Run Easy is a sick piece of software and at a great price." Reddit r/physicaltherapy
A sensor on the pelvis sees things video cannot. It measures how hard you hit the ground on each side, in units of acceleration. It sees whether the left leg loads more than the right. Those two numbers are useful for a runner coming back from a stress fracture or a one-sided injury. No phone camera can give them to you.
Where people get stuck
The complaints are not about the sensor. They are about the session it is sold inside. A runner books a clinic gait analysis, pays a few hundred, and comes out with a report and some exercises they could have found on their own.
"honestly it was a waste of money" Reddit r/running, on a Runeasi session
"he didn't really tell me anything I wasn't aware of. He did give me PT moves to do to strengthen my weaknesses. I did them for about a week before stopping" Reddit r/running, same thread
"I live in NYC- it was $500 with the discount I received!!! It was cool to see the videos and all but not 'needed'" Reddit r/running, same thread
"Like I know what I need to be doing, I don't need someone to tell me that for $100. But I also don't know what I need to do to fix it." Reddit r/running, same thread
The measurement was fine. The follow-through was not. A single session gives you a number on one day and no way to check it next month without paying again.
There is also the access problem. Runeasi's apps on the App Store had zero ratings when we looked, because the runner is not the customer. The physio is. If your local physio does not have one, you cannot use it.
The alternatives
Caden is an iPhone app. You film 5 to 20 seconds from the side. The audio is removed and the clip uploads to private storage under your account for the pose estimation. You get a form score out of 100, six dials for where your foot lands, knee bend on landing, knee bend at push-off, upper body lean, arm bend and head position, plus cadence. Freeze frames at foot strike, midstance and toe-off show you the evidence. A coach's tip gives one cue per metric. You can start a 4 or 8 week plan, three sessions a week, built from your lowest scores. At the end you film again and compare. It cannot measure impact, force, pronation or left-right load. It is the answer to "what should I fix and did it work".
Ochy is an iPhone and Android app rated 4.52 from 286 iOS ratings. It reports pronation, pelvic tilt, overstride, cadence and knee position from a side-view clip, and gives exercises. Coaches use it with athletes. The main complaints in reviews are accuracy disputes from coaches and physios who checked the same footage, and billing and trial problems.
"I've used this with clients and with myself and the feedback is just wrong." App Store review of Ochy, 2 star, GB
Movaia is a web app, not a phone app. You upload a video and wait, around 5 minutes for a normal clip and longer for slow motion, according to the vendor. It has a free tier of 2 limited analyses a month and a Pro plan the vendor lists at US$29.94 a year at the time of writing. It supports a rear view and gives a written report with target ranges. We found no user-written negative reviews. The wait and the upload are the trade-off.
A 2D physio video session is the middle ground. A physio films you on a treadmill from the side and behind, watches it back with you, and gives cues. No sensor, but a trained eye. Typical cost is 75 to 150 depending on country, at the time of writing. See gait analysis clinic vs app for when this is worth it.

Who should pick which
- You have pain that has lasted weeks, a stress fracture history, or one side that always hurts: find a physio, and one with Runeasi is a good pick.
- You want to know if you overstride, lean back, bounce or cross your arms: Caden.
- You want a number to check again next month without a booking: Caden or Movaia.
- You want a rear-view report and do not mind a web upload: Movaia.
- You want a human to watch you run and you have no injury: a 2D physio session.
- You are a coach with several athletes and want a fast side-by-side: Ochy or Caden.
How to switch or try
If you have had a Runeasi session, you already have a baseline. Keep the report. Film a side-view clip in Caden the same week and you have a second baseline you can repeat every month with no booking.
If you have not, start with the phone. It costs nothing to download and it takes two minutes. If the score is fine and nothing hurts, you have your answer. If something hurts, take the clips to a physio. Four weeks of video is more useful to them than a verbal description.
How to do it in Caden
- Tap Run a new analysis and set up a side-on shot. Film 10 to 20 seconds at your easy pace.
- Read the form score and the six dials. Tap the Where your foot lands dial first, since landing reach is what most clinic reports flag.
- Open Breakpoints and check the Foot strike frame against the hip.
- Start a 4 or 8 week plan on the Exercises tab.
- Re-film in week 4 and open Before and after in Stats.
- If a metric will not move or something hurts, take both clips to a physio.
FAQ
Can I buy Runeasi for myself?
Not in the normal way. It is sold to physios and clinics on plans that include the sensor. The runner uses it inside a session. Check the Runeasi site for current terms.
Is a Runeasi session worth it?
For a runner with an injury that keeps coming back, yes. The impact and symmetry data is real and a camera cannot get it. For a healthy runner who wants form cues, Reddit reviewers of the session say they got exercises they already knew.
Can a phone app measure impact like Runeasi?
No. Impact and asymmetry need a sensor on the body. A phone app measures 2D angles and timing from video. Caden says so in the app rather than guessing.
What is the cheapest Runeasi alternative?
Caden is free to download and gives a first score without a subscription. Movaia has a free tier of 2 limited analyses a month. Neither measures impact.
Runeasi vs Ochy, which is better?
Different tools. Runeasi is a sensor for physios. Ochy is a phone app for runners and coaches. If you are choosing for yourself, the choice is between phone apps.
Runeasi, Ochy and Movaia are names that belong to their owners.
