Semitone

About this app

Semitone is a tool for musicians that includes a tuner, a metronome, and a piano.

The design is as simple and easy-to-use as possible while implementing many useful details, such as:

* an option to set A4 pitch for alternative tunings

* the ability to manually set strong beats on the metronome

* dynamic resizing of the piano keyboard

Semitone is free, open-source software. The source code is available on GitHub under the GPLv3: https://github.com/tckmn/semitone/

Ratings and reviews

This app seems great so far - no ads, no unnecessary or intrusive permissions required, lightweight and simple. My only complaint is that the piano note B5 has an audio glitch, at least on my device.

I love that the tuner is combined with a simple piano in such a small app size. This would be hard to find in any other app.

This app does exactly what it needs without unnecessary graphics or animation to bloat it. All apps should be like this. Since there are no annoying ads, how can I donate?
