If getting to peak performance in your chosen sport is your goal, it's important to know what you're working with. It's easy enough to time a run, or check a batting average, but when it comes to even more fundamental things, it gets complicated.
Now, you can track with something like a radar gun, but that's not exactly something most of you carry around in your pocket. A phone, though? Or even a watch already on your wrist? That makes things much easier.
Arm Speed Motion Analyzer uses your iPhone or Apple Watch's built in sensors to give you tons of useful data on your throw and swing speed. These instruments have all you need for highly accurate readings, they just need an app to make the most of them.
Just wear your Apple Watch, or, with the new phone tracking feature, just hold onto your iPhone while you're swinging, to get the data. (Just make sure you hold on tight to your iPhone. That's not a piece of kit you want to fling through the air at high velocity.)
It has real-time speed tracking, which means you can get all the stats instantly, and don't need to press anything before you start. Just begin your session and start working, the app does the rest.
Push To Do Better
You can also challenge yourself to improve. You can store an all time top speed as a benchmark to match up to, mark a best overall session, or a streak. There are even achievements, like reaching 30mph, or a thousandth rep. So, if you do need motivation and fun little animations to keep you going, Arm Speed Analyzer has you covered.
In addition, there are more in-depth analytics. You can track how your speed and volume changes from week to week. Maybe you'll be able to see improvement, slips, or if that pre-workout you got is actually doing anything.
Between sessions, you can check previous ones, filtering by sport, date, or location to get useful data. That data never leaves your device, too, so you don't have to worry about anyone else snooping on your information.
It works for a bunch of different activities where you might need to know your own stats.
- Baseball
- Tennis
- Golf
- Frisbee
- Football
- Cricket
- Hockey
- Lacrosse
- Badminton
You can switch seamlessly from one spot to another, and check only sessions for that sport when you need to.
You can also integrate the app with Apple Health, to log your session as a workout and track it along with your other activity for the day. At least you get full credit for that exercise.
Arm Speed Analyzer is free to download and use. If you want more detailed analysis, you can upgrade to Arm Speed Pro, which offers more in-depth analysis like advanced charts, personal records, weekly trends and achievements, as well as giving unlimited session history.
