Arm Speed Motion Analyzer

Track your arm speed, no radar gun needed. Arm Speed uses motion sensors on your iPhone or Apple Watch to measure throw and swing speed in real time. Built for athletes who want to train smarter and track progress across every session. WORKS WITH iPHONE AND APPLE WATCH Version 3.0 introduces iPhone motion tracking: just hold your phone and throw or swing. Apple Watch support is still here and better than ever. Train with whichever device you have on hand. 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. SEE YOUR MOTION PATH Go beyond the number. Every throw and swing is captured as a 3D motion path, a ribbon that traces your arm through the air. Thicker means faster, and color grades your smoothness from fluid green to jagged red. Spin the path around, compare reps, and spot hitches in your mechanics that a speed reading alone can't show. 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. WEEKLY TRENDS AND ANALYTICS See how your speed and volume change week over week. A ghost line overlays your previous week so you can visualize improvement at a glance. Speed band breakdowns show where your throws are clustering, and daily activity heatmaps keep you accountable. HEALTH APP INTEGRATION Every session can log as a workout in Apple Health with heart rate tracking. Your training data lives alongside the rest of your fitness profile.
