Most intrusive ads of any app I have ever seen!

I work for a siren manufacturer in the USA so I was interested in seeing this app. There were so many full screen ads that it was annoying in just the first two minutes that I looked at it. Also the siren tone that is called wail is actually called Yelp in every siren I have seen.
Deleted it in about 5 minutes after install.
