Tunelight: Guitar Tuner

Tunelight is a tuner made for guitar and ukulele. Clear to read, quiet to use, so more of your time goes to the music. One pluck, and you know Pluck any string and Tunelight knows which one it is. The note you're playing, the target note and how far off you are, all at a glance. The moment it's in tune, the string glows green and your iPhone gives a gentle tap. Want to focus on one string? Tap it to lock it. Tap again to go back to Auto. Tuning, with a little fun Little Light rides the pointer, and its face changes the closer you get. Prefer something simpler? Switch to Dot any time. Every string you tune earns a sticker for your Sticker Book. Tune them all and a keepsake card appears, holding the date, the time and the colour of the sky. Save it to Photos, or share it.
