TuneCue

Tune by feel, not by sight. TuneCue is a chromatic tuner built around a simple idea: tuning is a physical task, so its feedback should be physical too. Instead of watching a needle or a dial, you feel a continuous pulse that tells you exactly where your pitch sits, sharp, flat, or dead center, through haptics alone. Play a note and TuneCue listens through the microphone, detects the nearest semitone automatically, and translates the distance from perfect pitch into a rate-encoded haptic pulse. The closer you get to in tune, the more the feedback changes, guiding you in without ever requiring a glance at the screen. If you want to look, the note name and cents offset are right there. If you don't, because you're mid-rehearsal, in a dark venue, or blind or low-vision, you never have to. TuneCue runs as a full standalone app on Apple Watch. Strap it on and tune without your phone anywhere…
