The iPad API does not include a "garbage collection" routine, so each programmer must ensure their App "plays well with others". Unfortunately, given the tendency to suddenly lose focus due to user early termination, this is an almost impossible task.
I generally have 8 to 10 Apps open and readily available on the double-tap menu, so my iPad memory tends to get overused. I use this App to regularly clean out unused memory so my active Apps run better.
About the only improvement I can think of would be the addition of a technical appendix giving definitions and typical usage for the status terms used.
I have and will continue to recommend this App to others.
