What Key

Doesn’t work. And if there’s something I’m doing wrong there’s nothing to help me. Do not waste your money like I did.

I have owned this for a long time, and rely on it to find keys to songs I want to learn to play. The best way to get highly precise readings on this app is to be sure your settings are configured correctly. I recommend going the settings tab and turning off all scales except "major". If you do this, most songs will pop up correctly and stay the same during the entire song. HOWEVER, if you have an ability to hear and recognize minor keys, and you are testing a song that you suspect may be in a minor key - turn off the "major" scale and turn on the "melodic minor" scale and give it a try. Also if you know how to recognize a blues tune, you may get good results from setting the scales to "major and minor pentatonic." If you just turn on all scales, the display is going to show multiple options at any given point during a song. It may also be worth noting that some scales are essentially the same but with a different starting place (ie G major Em) so if you have a bit of music theory to help you you will enjoy the app more.

I tried using it with my iTunes it just shuts it off waste of money!

It seems to be a good program however I tested it on my Roland Juno g. Keyboard. And found it is a half step to high in it's results. It is ok even great if you know that whatever results are shown is a half step to high and you adjust for it. I still give it four stars

I loved the old way that it just quickly displayed the major key. Now I see a bunch of graph lines and I'm trying to read what key by the jumping lines. Bummer.
