I don't mind ads. This, however, was glitchy with ads. Ads would play whether I clicked yes or no on the 'rewards'. Most of the time, if I clicked yes, it did not give me the reward and went back to the selection. If I clicked 'lose it' on the reward, it would play an ad anyway and half the time would still glitch me back to the selection. I gave up when this happened so many times in a row my phone heated up and the app crashed.
