This app keeps my Samsung Galaxy 7 free of unnecessary junk files. It tells me which apps i use a lot and which ones i don't use at all. When i get close to using up most of the phone's memory, i can quickly, easily delete gigabytes of files and get back to what i was doing. Few ads with free version - not annoying at all. The one issue that frustrates me is "deep cleaning" meaning beyond the easy stuff. This feature must be enabled in settings, under activated services. It hasn't ever worked.

I used to give this 5 stars, but since changing phones and the latest updates, I am going to have to delete it. When the free trial of the "Pro" version was available, I tried one of the battery-saving options, hibernating apps running in the background. It was a disaster. One of my crucial health apps stopped working properly, no longer sending alarms or prompts. I may have to delete and reload that app, and I am not looking forward to losing months of medical data.

It's handy & reliable. It doesn't do anything you can't do yourself, it just does it faster and more systematically. You may review every file it suggests for removal, or just select all and let it go. A handy app to keep unwanted and junk files cleared out, and apps put to sleep, regaining space and working memory. You'll probably want to turn off notifications from this app, because there are too many and too frequently. (I mean nag, nag, nag.)
