Tunelight: Guitar Tuner
Ukulele, chromatic, drop D
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Tunelight is a tuner made for guitar and ukulele, on iPhone and iPad. 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 its note to lock it and hear it. Tap Back to Auto when you're done.
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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Shift (Full Version): raise or lower every target note by half steps. Capo on fret 3? Choose +3.
• Tap a note to hear it.
• My Tunings (Full Version): set each string's note and save your own tunings.
• Made for iPad, in portrait and landscape.
• Fixed an issue where, on some iPhones, tapping to buy the Full Version didn't open the App Store payment sheet. If a purchase doesn't go through, Tunelight now tells you why.
• Once every string has been in tune, the round is done and you'll see it right away.
• A normal pluck now gets a response, and the pointer holds steadier. Dot is now the default pointer.
