Description by Ryo Ogasawara Written by the developer, not by AppBrain. Click to read.
Upload a carving video filmed head-on and the AI reads your posture to draw your board's trajectory as a top-down map. Then just tap a carve on the path and place a step you've learned -- only steps that fit the carves before and after are offered, so your line always flows.
