Fine Tuna

Fine Tuna is a precision tuner for musicians who care about the details—especially early music specialists who need to understand exactly what a temperament is doing. Fast, responsive pitch detection finds stable musical pitch through fast attacks, noise, overtones, and changing envelopes, making Fine Tuna especially effective on instruments that can be difficult to hear electronically. Created by professional harpsichordist and conductor Jeffrey Grossman, Fine Tuna lets you tune, see, hear, compare, and investigate temperaments visually, numerically, and by ear. Start tuning instantly in Simple mode, with advanced tools always just a tap away. You can even add a shortcut to open the tuner right from your phone lock screen!
