Honest swing analysis for everyone with a phone

Serious golf swing analysis has always lived behind hardware: launch monitors, sensor vests, multi-camera studios, and the coaches who own them. Meanwhile every golfer already carries a camera good enough to capture a swing — what was missing was software honest enough to measure it properly.

AnchorStance reconstructs your body in true 3D from one ordinary phone video — 34 joints and the club, on every frame — and measures 20+ swing metrics against the ranges good swings actually live in. That reconstruction is the product: you can orbit your own swing from any angle, jump to any position, and watch each number react.

We built it around three principles. Honesty over hype: every metric is labelled measured or estimated for the camera angle you filmed, and a clip we can’t read cleanly gets a “refilm” — never invented numbers. One fix at a time: an analysis leads with the single fault that matters most, with drills attached, instead of a wall of red. Consistency over highlights: there is no fake 0–100 swing score here; you earn Levels by keeping numbers in range across many swings, because that is what better golf actually is.

AnchorStance is built and operated by Trendblitz. It runs fully in your browser today — native iOS and Android apps are coming soon — with analysis powered by our own computer-vision pipeline.
