Be careful
I bought this thinking it would be awesome. Well it was. It does everything it says it can. Only problem is, where do you put your ipod? In your pocket? Not with this. Your pocket makes tons of noise. The only places you can use this are if you are sitting at a desk, or maybe jogging with it in your hand (which will probably still make noise for the microphone to pick up. Good app, just think about how useful it will be to you first.
