Hey everyone,

I’m a CS student and gym enthusiast, and I just launched a small app called Gymmie – AI Form Scanner.

The idea is simple:

You record your workout set →

The app detects your body keypoints →

It analyzes joint angles →

Then gives feedback on your form.

No workout planner.

No calorie tracking.

No social features.

Just form analysis.

I built it for the Gemini 3 hackathon, but instead of leaving it as a demo, I polished it and released it on the Play Store.

Right now it can: 

• Detect pose using computer vision

• Measure joint angles

• Highlight potential mistakes

• Give simple AI-based correction suggestions

I’m still improving:

Accuracy across lighting conditions

Different camera angles

More exercise support

I’d genuinely love honest feedback from people who actually train.

What I want to know:

Is the feedback useful?

Does it feel accurate?

What exercises should I prioritize next?

Would you actually use something like this consistently?

Appreciate any thoughts, even harsh ones. I’m building this to improve it — not just to ship it.
