Distance off the tee starts with arm speed. Arm Speed Analyzer lets you measure your throw speed with your Apple Watch or iPhone, so you can track progress, experiment with form, and throw farther.

Measure Your Throw Speed

Arm Speed Analyzer tracks your arm speed and peak acceleration through the throwing motion. Get your max speed instantly after every throw — backhand, forehand, or tomahawk.

Whether you're field testing new discs or doing form work, speed data gives you an objective measurement of what your body is doing.

Throw Farther

In disc golf, distance is directly tied to arm speed. By tracking your speed across sessions, you can see how form changes affect your output and focus on what actually adds distance.

Compare your backhand vs forehand speeds. Track how your arm speed changes as you warm up. Find out if that new x-step drill is actually working.

Build Consistency

The best disc golfers don't just throw fast — they throw the same speed every time. Use your speed history and trends to measure how consistent your throws are and build a repeatable motion.

Arm Speed Pro unlocks advanced analytics and your full recording history, so you can dive deep into your data and track long-term progress.
