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.
