I installed this app a long time ago. when I first downloaded it the app worked amazing and you only had to watch a single ad. Now you can't even get past the last ad because there is no way to close the ad after you have watched it and the screen is just the app advertisement with no option to use the ad killer. It may work if you download the app , but I'm not doing that because I don't want more junk in my phone. As of now this app is unusable. I'm writing this and immediately uninstalling it

An outstanding app. The fastest way to: close background apps; boost RAM speed by freeing up occupied capacity; clear temporary files and app caches; delete empty folders; and identify and clean up various data—such as duplicate, unused, or large files. It offers a streamlined experience, free from clutter or unnecessary complexity beyond the app's intended purpose. Wishing success to the manufacturer(s), and extending our thanks and appreciation.

Great app! Does exactly what it advertises. Ads are nowhere excessive. I approve, and highly recommend...09/11/23: (edit): I have tested this app now for several months and still recommend it. Developers! Keep up the good work! 09-04-26: Android 15 tried to zap your app, then after my upgrade to Android 16, Android 16 was supposed to handle memory better, but had to reinstall your app to kill hundreds of apps still running in the background. Used your app to clean everything up again.
