Hears the quiet ones
An unplugged electric sits far below what most tuners listen for. TuneGlass filters the noise and locks on anyway, including the low E that likes to jump an octave.
A little clarity. Every string.
Less noise.
More music.
A beautifully simple guitar tuner. Find your tuning. Get back to playing.
Coming soon to the App Store
Free. One optional purchase.
No ads.Ever. Not even “just one”.
No subscription.One purchase, if you want more.
Nothing collected.Audio never leaves your iPhone.
Open it. Play a string.
That’s the whole tutorial.
No onboarding, no account, no lesson funnel. The tuner is the product, and it is built to be trusted on the strings other apps get wrong.
Any tuning in a twist
Tap a string and every string turns into a wheel. Spin E down to D and the app recognises Drop D on its own. Presets for the rest.
Every instrument you own
Six, seven, eight and twelve string guitar. Four, five and six string bass. Ukulele. Standard tuning is free on all of them.
Precision mode
A ±10 cent dial for the final turn of the peg, tenths of a cent, signal and confidence meters, and plain-language hints when a reading is unstable.
Built for iOS 26
Native Liquid Glass, native wheels, native haptics. It feels like part of the phone because it is written for it, not wrapped around a web view.

One screen. Every instrument.

Questions
Does it work with an electric guitar that isn’t plugged in?
Yes. That was the hardest case during development and it is the one we tuned the detector on. Hold the phone near the strings in a reasonably quiet room. Precision mode will tell you if the signal is too quiet.
Why no ads or subscription?
A tuner is a thirty-second tool. An ad before it, or a subscription for a tuning you used once, is the thing people hate about other tuners. One purchase covers everything, forever.
What does it collect?
Nothing. Audio is analysed on the phone and never stored or sent anywhere. There is no account, no analytics and no third-party code in the app. The App Store privacy label says “Data Not Collected” because that is true.
Which iPhones and iOS versions?
iOS 26 or later. The interface is built on native Liquid Glass, so it needs the system that has it.
Which instruments?
Six, seven, eight and twelve string guitar, four, five and six string bass, and ukulele. Standard tuning is free on all of them; alternative tunings and per-string retuning are part of Pro.
I bought Pro and it shows as locked.
Open Settings in the app and tap Restore purchases. Purchases follow your Apple Account, so this also unlocks Pro on a new phone.
Support
A person answers.
Bugs, a tuning you want added, a string that will not lock on. Write and include your iPhone model and iOS version if it is about detection.
