At least have very long ad and then have immunity for few mins. Very annoying to keep watching the same one over and over again. It works VERY well, but only if you don't get annoyed with every single time you open app you immediately watch ad, only to be forced to watch another if you plan on doing ANYTHING on the app, period. 3 1/2 stars since it doesn't show any apps being run that are hidden.....it definitely closes at least most of them out, though. Going to try something else I think!

Every thing you do brings up an ad. A lot of the ads are loud video ads which let's everyone know that you're on your phone. Since everything produced an ad, I don't know if this app works or not. This app was a waste of time so I deleted it.

DISHONEST to start! went looking for settings of some kind to further figure out the process for enabling "Accessibility," as nothing the app instructed was even possible, nothing to click to bring you to accessibility option; the only option were to leave either a ***5 STAR RATING!!! YAAAY!!!*** Yaaa NO. The OTHER option was ***"COMPLAINT"***; Perfect, I thought. Except clicking "complaint" is a fraudulent option that goes nowhere!! Takes you back to the start!! I wish I could give negative!!
