Get your Captain Falcon on!
Choose a sound, hold on tight to your device, and FALCON PAWNCH!!

Falcon Punch will play the selected sound whenever it senses you have punched via the accelerometer in your iOS device or Apple Watch. When using Falcon Punch on an Apple Watch, sound will play through your iPhone's speakers. At this time, Falcon Punch can only be used on the Apple Watch when the app is open and showing on the screen. When paired with an Apple Watch Falcon Punch on the iPhone can play sound effects in the background while other apps are open.

Developers' Tip: We highly recommend Falcon Punching to the beat of your favorite song.
