Statterbox

Your kid already wears the sensor. Statterbox turns an Apple Watch into a multi-sport recorder and a motion coach for validated baseball and football actions. Start a session on the watch and practice like normal. The watch records wrist motion 100 times a second. With your permission, it reads heart rate from Apple Health and saves each session to Apple Health as a workout. After practice, we review the session and send your family a report: what repeats, what held up late, and the one drill to work on next, with a cue a kid can actually use. Basketball sessions bank captured wrist activity while shot detection remains in validation. WHAT IT READS - Baseball: swing rhythm, throwing mechanics, release timing, late-session hold - Basketball: captured wrist activity; shot and form reads stay hidden until independently validated - Football: throwing motion, release consistency EVERY NUMBER IS YOUR KID VS YOUR KID No comparisons to other kids, and no public leaderboards. Every reading measures your athlete against their own history: their best, their typical, their trend. The report says what improved, then hands over one drill with its cue, plus the check that proves it worked. BUILT FOR FAMILIES One family covers every kid and every sport, on watches you already own. Grandparents can read the report too. The athlete's own numbers are never behind a paywall. WHAT IT NEVER DOES No ads, no selling data, no location tracking. It makes no injury claims. A recording is never lost: the watch keeps every rep until it uploads safely. Requires an Apple Watch. Set up by a parent; made to be read by the whole family.
