Im okay with ads, but....
Not ones Im forced to view for a set amount of time. Every time you change a setting, you have to watch an ad for at least five seconds. Fine-tuning the settings could take you quite some time!
The app itself seems to be very well done, both visually and functionally. Lots of settings allows a highly-customizable app, if you have the time to watch ads. :)
With many of the free apps, ads are the "price" you pay; Im fine with that. This app, however, seeks to annoy you to the point that youll break down and buy the "Pro" version.
