Pretty good...with some faults
I bought this app a few days ago, and it works great, except for one thing. The microphone sensitivity is very high and in order to make your voice sound clear you have to almost whisper the note and the word. Also, it picks up the other tracks when you try to layer over them and yes it makes the sound richer but it also adds a piercing ringing to the song. Im probably only having this problem because Im using the iPads microphone, but in my opinion this app shouldnt be 4.00, maybe 2.00 or 1.00. But other than the mic the app is amazing. It layers perfectly, theres no delay in any of them like I had with other apps, love how you can change the beat and all that fun stuff. I still say buy it anyways, apart from the microphone problem.
