ActMonitor 4+

App is cool.

Add support for cpu monitor, and support for monitor in real time usage resources, in widgets.

Developer Response ,

CPU available only for our process
Realtime updates in widgets - unfortunately - no way

Missing one feature.

The app don't show amount of used memory per app. Only running time, priority per process name. Anyhow it's still very useful.

Nice app

The application itself is very nice and it is quite obvious that the creators have put an effort to make it reliable. But. The big idea behind iOS is that users don't need to care for administrating their devices other than installing apps, downloading music etc. most users don't get the difference between wired and active memory, and will get completely puzzled when they will see how much memory is actually free. So, this app puts user in a new role, which he had no need to play before: a device administrator. This is something user has no need for. Memory distribution is not necessary to know, battery - well the only thing you need is 'is it enough to use it till the next charge'. Device specs? Well, nice read, that's it. So, even though as I said it is quite a nice app, I don't think one really needs it for anything else than over-caring for the device.
