Your Apple Watch can help you tune a guitar
The Apple Watch is handy for a lot of things, and now you can use the wearable when you tune your axe. Thanks to the folks at IK Multimedia, when you employ the company’s chromatic UltraTuner app for iOS, note info is beamed to your wrist while tuning that stringed instrument. The software’s Stage mode offers a UI that takes up the entire screen of a phone for maximum visibility, and when this setting is selected, a smaller version of the interface is displayed on that wrist-worn accessory. IK Multimedia claims that UltraTuner is ten times more accurate than mechanical strobe options — down to +/- 1/100th of a cent. As you might expect, those figures make it the most accurate tuner available for iOS. If you’ve already splurged for the $5 app, you’ll need to update to the most recent version to pair it with the Apple Watch.
