Awesome First I was a bit skeptical. Would this app really satisfy all of my auditory needs? I gave it a spin and haven't stopped listening. I deleted my entire 400 album music collection, just to listen to this fantastic app instead. First "woo" took me right back to my trip to Bali, then next, right back to my childhood in Copenhagen. If this ever becomes a paid app, I implore, nay order! you to sell whatever you must to own this super app. Best regards from a dedicated woo fan. Also, go James Randi!

Changed my life! excellent! I now no longer make strange noises to bypassers or to people on the bus, but leave it to this fabulous app and can now concentrate on making strange, jerky movements. thanks.

Woo da thunk it. Crazy funny sound attracts women like mad. Bonus: it also makes a great pet call. Not sure of long term affects if you have OCD like me.

It's nice :) Funny and kiddish, Woo is exactly the kind of thing to make you laugh for a minute in the middle of a busy day. Plus, the curvy lines are fun :P

Innovative No options/settings. No other sound types to choose from. And crashes few times. But the way app is developed is really innovative. Could've been good if you add more sound types.

Don't leave home without it! This app is the best. I love using it to annoy my girlfriend when she's cooking dinner. The best thing is to just lay it down flat and let it repeat one annoying tone.
