iOS beta now open

"My knee gave out mid-marathon prep. This is how I came back."

I built an app that analyzes my running form from a 15-second video. Almost 2 years later, I'm back in shape. Now I'm sharing it with you.

Let me show you something outside of my usual Fintech topic that has changed my life.

Was watching Barcelona Marathon '26 this weekend. I remember prepping for my first one, same marathon, back in '24.

My knee gave out mid-marathon prep. I wasn't ready. I wasn't running properly. It was a meniscus problem. The doctor said I might need surgery.

I even flew to Barcelona for that marathon - just to watch other people run. I was devastated.

I've been very careful with running since then. Started obsessing over what went wrong. What was I doing that was destroying my knees every time I ran?

So I did what any engineer would do. I built an app for it.

KneeGuard analysis report showing running form

I built KneeGuard - an app that uses computer vision to analyze running form and detect the patterns that hurt your knees.

Every time I go to the gym and run on the treadmill, I record a couple of 15–20 second videos. Then I analyze them to detect potential problems - overstriding, stiff landings, hip drop, excessive bounce - so next time, I run better.

Almost 2 years have passed and I'm back in shape.

Marathon this year? Possible.

Never give up.

I wanted to share this with all of you - it genuinely helped me get back to running. And I think it can help you too.

Questions?

How accurate is it?
KneeGuard uses computer vision models to detect the running form issues that lead to most knee injuries. It is not a medical diagnosis, but it catches the patterns that matter. Always consult a doctor for existing injuries or pain.
Is my video private?
Your video is processed securely and never shared with anyone. You can delete your data anytime from within the app.
Does it work on a treadmill?
Yes. Treadmill and outdoor both work. Side-view angle, about 1-2 meters away. I personally use it on the treadmill every week.
What about Android?
iOS only during beta. Android is coming soon. Join the waitlist and we will notify you.
What happens after my 15 credits?
Purchase a credit pack in the app. Or give us feedback at contact@kneeguard.app and we will top you up for free.
Who is this for?
Any runner who wants to protect their knees. First 5K, marathon prep, or coming back from injury. If you run, this is for you.
