Response from developer

Thanks for funny comment. As you can see a lot of people like it or even love it. But who likes it last time son’t write review. And somebody who didn’t spend a penny so entitled to write his opinion. Tolerance is good, when it makes sense. Too much of tolerance is really bad. If there is really a problem contact us, help improve, we’re open. But giving 1 star for spending 30 seconds in app. Why?!

Just add

This app’s main purpose appears to be serving up ads. I found it to be nearly useless

Response from developer

This app is free to use with having ads in the app, to remove there is an option to upgrade and get 8 more apps in the same price and help keep us building apps. Everybody want's everything for free, but don't think how developer who does it should live on free stuff. Store doesn't give anything for free even with by watching ads. Can't imagine how to live then if nobody pays you or watch ads. But looks like it is hard to make somebody happy without giving everything for free. Nowadays is how it is...
