Ratings and reviews

I'm going to rate this one star. The former version of this app may have had ads, but I couldn't close THIS VERSION without literally a dozen ads getting thrown in my face. That's an absurd feature, one the former version didn't have. Too bad it was removed from the store, I regret uninstalling it. I understand the need for ads, since it provides extra revenue, but this is not the right way to go about it. You lose potential customers with this, not gain them. Fix it, for your own sake.

No longer cleans junk files. So crammed with ads, it no longer actually cleans junk files. I tried three times after trying to navigate around ads. Every time I hit the back button, was just continual loop of different ads. This app serves no useful purpose. I had used it and recommended it for years, but permanently uninstalling it now.

What is this? I have this app on my other phones and tablet. It can be stored on your SD card and has a notification cleaner. It is not on my list of apps, even though it is installed. Explanation required! I also have a subscription for the light version. Uninstalled. Heap of garbage now. I have found a better one with less adds and it's free! Keep it!
