Challenge Flow

Built for a real product surface, not a landing-page mock.

01

Calibrate framing

We ask for a clean full-body frame first, because counts without framing control will be noisy across phones and laptops.

02

Run a fixed countdown

Every mode stays in a 30-second sprint so leaderboard scores remain comparable for this release.

03

24h leaderboard

Your tag and reps stay on the board for 24 hours, then roll off automatically. Beat your tag again to refresh it.
