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. BUILT FOR YOUR SPORT Baseball throwing and batting Softball pitching and hitting Pickleball serves and volleys Tennis serves and groundstrokes Golf swing speed Disc golf and frisbee throws Football throws Cricket bowling and batting Hockey and lacrosse stick speed Badminton, racquetball, and more 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. FREE TO USE Arm Speed is free to download and start tracking. Upgrade to Arm Speed Pro to unlock 3D motion paths, unlimited session history, advanced charts, personal records, weekly trends, and achievements.

We recently have updates that should make the Apple Watch experience more stable. If you are still experiencing issues, can you email us at support@fre-studios.com so we can look into your issues? Thanks for trying Arm Speed Motion Analyzer. ### 5/5 — Excellent App *2026-03-03* Does a great job of calculating speed, excellent integration with Apple Watch ### 1/5 — Disappointing start *2025-01-12* Installation was quick and easy, as was updating the orientation setting for the throwing hand. Unfortunately, that’s where the good news ends. Measured arm speeds were very inconsistent and much lower than when measured with other devices. (Radar and Tech Disc.) ### 5/5 — Works well *2025-01-04* This app matches my speeds to what a tech disc does for disc golf. ### 5/5 — Amazing *2024-12-18* This app is so fun I love how it measures your speed of throwing, punching, and frisbee speed it’s so cool and fun i recommend this for baseball pitchers with Apple Watches so much easier than buying a ray gun ### 2/5 — Works great once *2024-10-09* Works great once then add city. Scroll add pop dismiss scroll add pop you’ll see. Uninstall. ### 1/5 — Doesn’t sync *2024-09-22* It does not sync with iPhone app. The “history” section only shows the guide and the chart section is blank. If I go to settings in history nothing happens. If I go the settings in charts it crashes… **Developer response:** Hey there, we have made updates to the app that should fix this sync issue. If it's still occurring please email us at support@fre-studios.com ### 2/5 — Not Working *2024-07-19* Free version of the app was working fine but as soon as I paid the $4 for the full version of the app, it stopped sending the information to my phone. I’ve reset both my watch and phone, and deleted and redownloaded the app on both as well. Checked my connection and that’s not the issue either. Emailed support and have yet to receive a response. If this problem was fixed I’d give it 5 stars. ### 1/5 — App stops working *2024-07-11* The app on the watch works just fine. But for some reason, it won’t open on my phone. I tried uninstall and reinstall it, but after it tried to sync the records, it crashed and wouldn’t open anymore. ### 2/5 — for my style not as accurate *2023-12-30* shows arm swing speed but seems unable to show linear speed accurately . so swing arm for approach shot , seems to have some data. pull a fast drive and shows less speed. if all your shots are arm swings maybe ok. ## Frequently asked questions about Arm Speed Motion Analyzer ### What does the Arm Speed Motion Analyzer app do?
