I once hated ads cause they get in my way; now, I'm infuriated by the ads. The ads in this game often show up after a run, what's even more annoying that waiting for it to finish so I can skip it, is that there's a small chance for the app to crash after I close or mute the ad. Some ads are bigger culprits than others. REMOVE the ads in between runs and ensure that ads are available elsewhere... I hate it when the app runs slow after viewing an ad and it causes the app to crash.
