Ads in a paid app? Really?

This USED to be a good app, but now the interface is cluttered with photo icons (not a bad idea but it should be a setting - I already know what my toothpaste looks like) and worse - ads. I paid for this app, and you have broken the long-standing understand that paid apps do not have ads!!! Bad, bad, bad.
