It's motivating, but pro mode is a disappointment. Now rather than being able to watch an ad for double coins at the end of a session I earn the same base coins with the option to pay real money for increased coin earning. I already paid for pro mode! And pro mode feels entirely necessary for the white listing feature. Without it even apps like a music player or calculator, that are sometimes required to be used while you are focusing, will kill your tree. I feel ripped off.
