PerfectTune - the Ultimate String Tuner

By 31tone

Open iTunes to buy and download apps.


PerfectTune is the ultimate tuner for stringed instruments. Not only does it feature a lightning fast pitch detection system, that is unparalleled by any other tuner on the AppStore, it also comes with an innovative multi-string layout that lets you tune your instrument quickly to a great variety of tunings.

PerfectTune features optimized algorithms for Guitar, Bass, Banjo, Violin, Cello, Ukelele and other stringed instruments, and for each these you can choose from a range of relevant tunings. There's dropped and open tunings for guitar, period tunings for lute, support for 5 and 6-string bass guitars and various types of banjo.

In the innovative Strings view, all strings of the current instrument are laid out on the screen, making it very easy to quickly tune up. When you select a different tuning, such as Open D for guitar, the pitches in the Strings view are adjusted, helping you adjust the changed strings in a matter of seconds.

The smart calibration system lets you either enter a reference frequency by hand, or calibrate automatically to a played note. This makes it very easy to get yourself in tune to a fixed-pitch instrument, such as a piano, organ or pitched percussion.

PerfectTune is versatile, fast and precise and makes it fun to tune your strings!

(warning: iPod Touch users will need a microphone for PerfectTune to work!)

Great app, when it worked..

I can use the main screen to tune my ukelele, but now when I try to switch to tone the app crashes every time... If they fix that minor bug, this app would be perfect. It helps tune a wide variety of string instruments and is easy to use and understand. But they should really fix this bug.


It worked good for awhile now it crashes when I switch tabs -_-

Stopped working

Used to be my go to tuner. What happened? Never registers pitch now. Is there a fix coming?
