worked when I needed it.

well, 1st, to get any sound, you need to play full volume... you will only hear some frequencies.... bleeps once in a while...

I was there, reading my ipad outside my condo on the terrace, but I kept getting mosquitos around me... buggin me...

downloaded the 1st anti mosquito app to test that science ... this app... and well... it worked...

I did not rate 5 stars because of the ads and the strange fact that a police car briefly flashed his lights right when he passed in front of my condo... but didnt stop... strange, just like this apps mosquitos repelling properties.
using ipad 1 btw... no os 6
