How does the FramIQ bike fitting app work?

You film your pedaling from the side on a turbo trainer for a few seconds with your iPhone. FramIQ uses Apple's Vision Framework to detect 17 body keypoints in real time and measure your joint angles: knee (optimal range 141-152 deg), hip, shoulder, elbow. All processing is 100% local - no video is sent to any server. You then receive precise millimeter-level recommendations for saddle height, stem length and handlebar width.

Does FramIQ replace a professional bike fit?

FramIQ delivers the same level of analysis as a professional fitting for most cyclists, at a fraction of the cost (29 EUR vs 150-350 EUR in a studio). It was built by Gaspard Blanc, osteopath D.O. and bike fitter, which guarantees a rigorous clinical approach. For complex cases (serious pathologies, significant asymmetries), an in-person fitting remains complementary.
