Pitch•Lab is an app that produces reference pitches for tuning various stringed instruments.

The pitches are grouped into sets that correspond with stringed instruments and arranged into instrument families. The pitch that is produced is a pure sine wave.

It's easy to use! Swipe left to right to pick your instrument family and then swipe up and down to pick your specific tuning. Tap a note to hear the pitch. Tap the smaller button to produce a pitch one octave above.
