Edit 5/18/22 The new ads you all started are horrible! Now when I run Super Economy it jumps to a full screen ad that I have to click off two or three times before I can use any other tools! I won't go through that every time I go to close things on my phone! If you don't fix it I'll go find something else. I love this ap and use multiple times each day!

Has advertisment feeds from ad servers which hijack and lock up phone screen. Application loads ads that completely take over the screen and switches between the ad and the Google store to force you to download the application from the app. It becomes an infinite loop and the only way out is to somehow get back to your home screen and kill dfndr performance.

This app is very intrusive. I'm busy working on something important. I need to clear up space. So I delete couple files. Then this pop up on screen asking if I want to delete residual files. Which is annoying. So I pick yes. It takes me out of my program to the apps screen. I Totally lose my train of thought. Worse I plug in to charge. It takes me out of what I'm doing. To the app screen. I was about ready to break my phone because of how frustrating it is.
