This app is currently free on the AppStore.
Basically four pages of info about your iPad, wifi, running processes, free ram, battery life, disk usage etc..
Odd that it shows 3G taking some time in the battery status page, since I have a wifi only iPad. IOS must show this for some network process by default, or his code is reporting wrong.
Think it just shows expected continuous 3G usage given the existing battery level.
What surprised me, and shouldn't, was how little free ram there was.
