This app does nothing

I downloaded this app to clean the memory space on my iPad. I did a scan several times and it kept coming back with x number of mb of junk files on my iPad. Ok, so now what? So I paid that .99 because I thought it would enable a function to cleanup those junk files. I did four separate scans using the same settings. Each scan came up with different information. The first scan told me there was ZERO junk files on my device. Next scan said 360mb of junk, next 120mb of junk and the final said 245mb of junk files. So the scan is complete false. Also, how the heck do you remove these "junk" files and also where is a detailed list of what these files are? I wasted $.99 and just deleted the app because maybe the app was the "junk" file. Totally disheartened.
