Tuning fork1.0.4

Play an audible reference tone from your phone when you need a steady sound for tuning an instrument by ear. Musicians can request the tone during a tuning session and compare each string or note by listening rather than following a visual meter. The same reference sound is useful in other situations that call for a musical pitch.

Tuning fork recreates the basic role of a traditional tuning fork in digital form, giving players a practical alternative to carrying a separate physical fork. It is aimed at musicians who prefer listening-based tuning, as well as anyone who needs an audible musical reference. Keeping it on an Android phone makes the tone available alongside other mobile tools used during practice or performance.

Tuning fork is an open-source Android app in the Video & Media Players category. It requires Android 6.0 or newer and uses a Universal architecture. Version 1.0.4 adds support for edge-to-edge display layouts and introduces a dark theme. Developers can build and run the app with Android Studio, while contributing to poretsky/TuningFork development through GitHub requires creating an account there.
