Ridiculous amount of pop-up ads.

By the time you get through the countless annoying pop-up ads (many where you try to close and accidentally end up opening a new ad window), your hear rate is probably up by 30bpm out of frustration before you get to even begin the monitor. If youre going to place ads in your app, dont be annoying with it.
