Purchasers of IK Multimedia’s UltraTune iOS app can pair the tuner with the Apple Watch via the Watchkit extension app. This will allow you to see note data via UltraTuner’s “Stage” mode. With Apple Watch, you can also select an alternate visualization that simply shows the note played, along with arrows below it to indicate whether the note is flat or sharp.
UltraTuner can be purchased as an in-app purchase within AmpliTube for iPhone and AmpliTube for iPad, IK Multimedia’s iRig-compatible guitar modeling software.
