What Ad

Do not give 1 star rating just if you are annoyed by ads or have personal attitude problems against ads See the point of the app.

What Ad uses a big ad network to show you ads but in a way that you chose a topic of a day or week and then you can test what kind of ads you see afterwards. It's a measurement tool to determine how much you have been listened via your phone microphone and location based tracking to analyze what you like.

This is probably most stupid app idea ever but it may open some peoples eyes. See that this app itself doesn't require any permissions at all.
