Wenn dann Zufallstreffer

Das hab ich mit dem Ohr schneller raus. Griff ins Klo.

Neue Version - neue Bewertung

Inzwischen funktioniert das Programm ordentlich. Mit vertracktem Jazz kann man ihm noch nicht kommen aber Pop-Lieder gehen inzwischen meist.

Bug issues

What key does not work!!

ellex6 · 16 years ago

Whenever I launched this application, the iPhone desktop appearance became striped. Even after I quit the application, the appearance of the menu would not return to normal until I restarted the iPhone. I regret paying anything for this app.

This app does not work

Toronto_Gary · 15 years ago

This app does not give the correct key or key signature of even the simplest notes. I also ran the app on the ipad and the iphone a the same time and they were both producing different results. Another free app that I already had and Logic both agreed with each other and they keyboard.

Not very good

Coolbreeze01 · 10 years ago · v3.5.1

This app promises much more than it delivers. After trying it for awhile in both Live Music and iTunes mode, I could rarely get What Key to decide on which key any song was being played. Its a clever idea, but this app is just not ready for prime time.
