All the tabs give useful information about the device. It is up to the user on how they use them. May be not all of them need all the info. But a lot of our users have found each of the tab helpful in one way or the other, as can be seen from the reviews itself.
A sample of them below:

"If your iPhone is running slow, or is hanging up while playing Risk or Monoploy, punch up this excellent app which mimics the gadget on Windows 7. Instantly know by easy-to-read dials when to free memory, etc! Then you can use whatever memory-freeing app you have to speed up your system! Cool!"
