Next Hold: a climbing coach on Snap Spectacles

A Lens for Snap Spectacles, built for the Learn AR with Spectacles challenge.

The problem: newer boulderers stall halfway up a problem because they can't see their options from where they hang, and a phone means letting go of the wall.

What we built: stand on the mats and it plans for your height from your eye level, with nothing to type. Pinch for your beta and every hold gets a ring for your reach. On the wall it stays quiet and hints only when you ask. 41 scenarios run in the Lens Studio preview, plus 220 checks on the planner. The climber in the cover is AI-generated, not a Lens recording.
