SeePU shows the current CPU, RAM and data usage in the notification area of your Android phone.
You can easily see whether your processor is being heavily taxed - and for example let it finish its job without burdening it further - or is sitting happily idle, ready for action.You can also monitor network usage, just like the tiny arrows that blink on Blackberry Devices to let you know it’s exchanging info with the network.
SeePU is highly optimized to use as few resources as possible, and you can choose the update frequency.
