UltraTuner uses your Apple Watch to tune your guitar

If you want to bring your guitar tuning skills into the digital age, IK Multimedia will help you with that with their UltraTuner app for iOS. The app will show note information onto your Apple Watch while you tune your axe. If you want full visibility, the app comes with a Stage mode. In this mode, you’ll see a chromatic tuner on your smartwatch. The company boasts that the app is 10 times more accurate than mechanical strobe options (down to +/- 100^th of a cent).
