Scroll add pop dismiss scroll add pop you’ll see. Uninstall. ### 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. ### 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. ### 2/5 — Basic functions, not working right *2023-02-21* It seems like this would be an easy app to run, and if I get it working I’ll update the stars, but right now it is not syncing my results to my phone and I’ve checked everything I know to. The app on the watch I recording just fine. ### 2/5 — How do you see history on iPhone? *2022-04-15* I been using it over a week. History page is still waiting for 5 or more record. We’ve been swing softball bat and throwing ball with app started on Apple Watch. Speed records show 25, 40, 50 mph and we save it but doesn’t come up on phone at all. Help please. ## Most critical reviews (10 lowest-rated) ### 1/5 — What happened *2026-03-09* This used to be a decent app but with this new update it’s no longer working on my Apple Watch, says failed to start workout even after resetting and updating the watch it still won’t work but loads up and works fine with my phone **Developer response:** Hello, sorry to hear about the issues with Apple Watch setup. 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. ### 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.) ### 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 ### 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. ### 1/5 — Doesn’t work at all *2023-11-05* Threw a test disc and got 22 MPH. Threw much faster to see the difference and got the same speed. ### 1/5 — Crap *2023-10-02* App on watch won’t sync to app on phone what’s the point in an app that does not work properly ### 1/5 — App no longer works *2023-09-28* Watch portion works fine (accuracy has always been in question), but we can no longer open the phone companion app. ### 1/5 — No longer works *2023-07-18* App worked initially, but then stopped. Watch will still show numbers, but watch app and phone app won’t communicate, and none of the recommended troubleshooting has worked. ### 1/5 — AVOID. Does not do anything *2022-09-20* Apparently it uses iCloud to “sync data” from watch to phone. However. This feature is non-existent because no where will you find an export or restore from iCloud data feature. Nowhere in settings on either watch or phone app will it allow you to actively grab that data and place it into, what I can only imagine is some sort of chart on your phone. An excel spreadsheet would be more useful. Wasted $3 and an hour of my life trying to get it to work. Giving up and deleting. While f-in around with it, each time I try to adjust start & end dates, it just crashes. TL;DR: Does not work as advertised. ### 1/5 — Doesn’t measure very fast speeds *2021-12-02* I’m a boxer and and maybe I’m dumb but it didn’t measure my punches but it did when it came to slower movements around 40mph. It could be the app or maybe my SE has not the fastest tech for speedometer or something but it didn’t measure my punches for some reason. ## Most praised reviews (10 highest-rated) ### 5/5 — Excellent App *2026-03-03* Does a great job of calculating speed, excellent integration with Apple Watch ### 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 ### 5/5 — It works well *2022-03-07* Great app, works very well and easy to use. ### 5/5 — Baseball practice *2021-06-28* Used this to recondition my arm post pandemic lockdown. Now back to my big league self. ### 5/5 — Interesting App *2021-06-26, version 2.1.1* Fun for impromptu throwing contests with the boys. ### 5/5 — Greatest *2020-11-21* It’s the greatest app I’ve ever owned ### 4/5 — Sensational app *2022-01-14* I use this amazing app to measure how fast my arm moves in a jerking motion for the various sports I do. So far my high score, so to speak, has been 34 MPH. It really adds an extra sense of pleasure to my sports and is fun to compare arm speeds with friends ### 3/5 — Super inaccurate *2022-10-12* High reachback it says I can throw 75mph but with a lower reachback it says 56 discs end up same distance it’s impossible I’m throwing at 75mph but only getting 350’ ### 3/5 — I like the idea, any help? *2021-06-25* This app isn’t recording speeds on my Apple Watch series 3, also when it does it only says I’ve thrown at 33mph even when I throw a disc 400 feet, the math doesn’t add up --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
