It doesn't guess.
It measures.

Centimeter-level measurements, calibrated on 1,000 real body scans. Asymmetries, posture flags, ratios — the things generic plans can't see.

04 · Loop Coach

A coach that knows you.
Actually you.

My shoulder feels stiff — should I skip overhead press?
Your scan flagged mild shoulder protraction, so pressing is already reduced this cycle. Let's swap to landmine press — same muscle, safer arc.

Answers about you — never generic advice. Voice or text, on every screen.
