Enough with the pop-up ads! I don't mind if an app has ads, but if I'm going to be interrupted by a 15 second video every 5 seconds while I'm checking off my list I'm deleting your app. And no, I'm not going to subscribe just because you keep popping up the subscription page. If I have to pay to make the app decently usable, you may as well require I pay for it to begin with.
