About this app

Tuner app for tuning musical instruments with features like:
* Detect pitch based on autocorrelation and FFT spectrum.
* Accuracy improvement by evaluating the spectrum phase information and polynomial fitting.
* Show how pitch changes over time.
* Basic instrument database (chromatic, guitar, bass, violin, ...)
* Support for custom instruments
* Several temperaments like equal, just, Werckmeister, Kirnberger, ...
* Non-12-tone temperaments (EDO 17, 19, ..., 41, 53)
* Scientific settings like FFT window size, FFT window type, overlap and more.
* Open source (https://github.com/thetwom/Tuner)

Ratings and reviews

absolutely brilliant tuner! I discovered this just last night. I used the pro version of Datuner for years but the version I have been using does not work on Android 16. found several others including the Peterson strobe which I was looking at purchasing. But I found this one before I purchased anything! beautiful clean interface, open source/free, super accurate, and no ads. thank you so much to the Dev for sharing!

Where has this app been hiding?! This is the best microtonal tuner for Android! I have been searching for a long time for anything useable & only found a web app. I even resorted to buying "Entonal Tuner", which is utterly broken on my current phone & buggy on my tablet. Now this has everything I need & spares me from programming my own app. Thank you so, so much! Finally I can easily tune my 22edo instruments (& 1 in 41edo) on the go with my phone, even without cell signal. What a blessing!

I like that it allows for microtonal tunings. Very useful. But I would like to be able to make the display look different: the area that tracks the pitch could be bigger (whole screen, not half), with smaller spacing between notes, so that more notes could fit on screen, that would be more useful for tracking pitch when singing.

What’s new

v9.0.0:
- Initial support of stretch tuning (predefined tables required).
- Option for Helmholtz numbered octave representation.
