Punch Velocity

How fast you can punch? With your Apple Watch, throw a punch and instantly measure key metrics—velocity, g-force, and duration—displayed using a nice graph on your iPhone.

How fast is your punch?
An untrained puncher may hit speeds around 7 m/s
A professional boxer can reach up to 20 m/s with a cross punch
A professional boxer jab typically peaks around 11.5 m/s

Setup Instructions
The arrow on the Apple Watch face indicates the punch direction.
To adjust it based on your watch orientation, simply long-press the arrow to flip it to other direction.

How to Use
1. Throw a punch.
The velocity appears on your Apple Watch.

2. View detailed metrics on iPhone.
Tap the velocity button (e.g. “5 m/s”) on the Watch to send the data to your iPhone for further analysis.

3. Measurement behaviour:
The displayed velocity updates only if the new value is higher than the previous one.
Tapping the velocity button resets the reading to 0.0 m/s.
For best accuracy, use straight-line punches like the jab or cross.
