REAL-TIME SPEED TRACKING
See your speed instantly after every throw or swing. Arm Speed detects each motion automatically, no buttons to press, just start a session, do your thing, and watch the numbers appear. See device acceleration change in realtime: even the slightest device jiggle will impact real time acceleration.
PERSONAL RECORDS AND ACHIEVEMENTS
Track your all-time top speed, best session, longest streak, and more. Unlock achievements as you hit milestones., from your first 30 MPH throw to logging your 1,000th rep. Celebration animations fire off when you break a record or unlock something new.
