User Reviews and Ratings
★★★☆☆Good but needs some work
The app works well for instrumentals. If there are voacls, it will throw off the app. It's good but of course could use work.
★★☆☆☆Works half the time
Reads at least half the songs as Bm. Almost seems like it defaults to that.
★★★★★Great for singers
Sing into the microphone until the percentage at the bottom of the screen gets to 100%. And up pops the key you're singing in.
★★★★★Nice
I am a Audio engineer and every sense I ran across this app it have been a time saver for me for when I am recoding singers who need the auto tune in the right key. This app help me with the key that the song are in so I can set the key and note scale so the auto tune can correct the singer notes. This help me with hearing the key without using it but I still use this app to make sure.
★★★★★Bugs
I love this application but I couldn’t open it today. Seems there are some bugs that need to be fixed !!
