Anton's pack is good but it records stuff I don't offer on the site: Video Uploads, File Uploads are two. I may purchase it and see if I can add other stuff like Modzzz Tutorials, Stories etc.
His mod also reports on usage time in minutes, but as far as I know that's the only field not included in Cheetah or Dolphin. Thus his module may only be accurate from the day it is installed.
I'm in the mood to try developing my own script to do this using a program called AppGini which I've had for years.
