SoloTuner: hear the string, not the noise

SoloTuner is a chromatic guitar tuner and string instrument tuner that tries not to get in your way. Solo here means one clear job: help you find pitch, not a wall of lessons, tabs, or extras. The chromatic tuning gauge always works accurately: it shows how close you are in cents to the nearest semitone in range, whichever listening mode you pick. That full chromatic behaviour is part of the app. Note and cents tuning is not something we treat as a separate "unlock". You also get a large, easy-to-read display, a string row you can scrub like a little fretboard, and a choice of how the app listens (multi mode, with different options).

Listening modes

There are two main modes available. We hope to offer more in future updates. Typical pitch ranges and the fuller explanation are in About.

Fast: detects a little sooner and feels more reactive on the gauge. The trade off is a narrower reliable working range than Balanced.
Balanced: for everyday tuning, more reliable for most sessions, a wider usable range, and a little less snappiness than Fast.

Visual Guide: The string row dynamically highlights the target string and tracks your pitch with an indicator, making it easy to see which way to turn the tuning pegs.

Make it yours

Set the reference pitch for A in Settings. 440 Hz is the usual default, but you can nudge it to match orchestra, studio, or band practice (conductors and sections often agree on a specific A). Choose an instrument and tuning from the catalogue, star favourites, or build custom tunings if you string things differently. Perfect for standard setups or alternate tunings like Drop D, Drop G, and open chords. No account needed. Your choices stay on your phone between sessions.

Nice touches

Acoustic guitar, electric guitar, bass guitar, ukulele, violin, viola, cello, and double bass setups available from Settings.
Scrub the string row on the main screen to hear the tuning in context.
Mute the mic from the instrument tuner when you're finished.
No ads included. If that changes later, we'll say so clearly in the app and in our privacy policy. Link at the bottom of About.

Note names use the usual A to G letters on screen in every language.

Day to day

Stage, sofa, or rehearsal: open, listen, tweak, done. We're not trying to be an all in one "learn guitar" hub; we're trying to be a precise guitar tuner you reach for without thinking — yet intuitive enough if you are still learning.

Mic behaviour

The mic is for tuning. If you switch apps, screens, or the phone sleeps, audio comes back when you return. Give the readout a moment to settle; that's normal.

Tips for a steady reading

Quieter space, fresher strings, and holding the phone closer to the instrument all help.

Looking ahead

We'd like to offer more listening options for different situations, keep polishing the modes you already have, and grow the instrument catalogue over time.

Tell us what you think

We would never assume this is the best instrument tuner app on the store. We only want to keep improving it with your help. If something feels off, you have an idea, or something breaks, please say so plainly. Links to send feedback (and report problems) are at the bottom of About. On Google Play, your app listing also shows how to contact the developer if that's easier for you. Either route is welcome.

If you want a straightforward chromatic guitar tuner with listening modes you control, SoloTuner is for you.
