"The combination of crash reports provided by the iPhone and System Activity Monitor helped me determine that I had an issue with contact syncing that caused my iPhone to drain with alarming rapidity." -

"This App is similar to the Mac OS Activity Monitor in that it shows you in real time which apps or processes are running and more importantly which ones are running with high amounts of processor time. If you're not playing a game or doing something else that would task the processor then your device should be running with the majority of the processor count in "idle." If it's not, you can quickly identify which App or process is causing a problem.

I highly recommend System Activity Monitor as a troubleshooting tool!"

"System Activity Monitor is simple and it works quite well, without any frills or flashy graphics." -

"5 STARS!!!
This the first rating I have ever given because this app gave me my IPAD back. it was crashing all the time until I purchased this app."

System Activity Monitor (TM). It's like the Activity Monitor on your Mac but for your iPhone.

Memory types:

Free memory
This memory is not being used currently

Wired memory
This information can't be moved to disk, so it must stay in RAM. The amount depends on the applications you are using.

Active memory
This information is currently in RAM and has recently been used.

Inactive memory
This information has not recently been used but will remain in RAM until another application needs more memory but no free memory is available. If called upon by a process, this is quickly changed to Active memory; if it has been swapped to the hard disk, it will be moved back to RAM and marked as Active.

Page ins / Page outs
"Page ins/outs" refers to the amount of information moved between RAM and the hard disk. This number is cumulative amount of data that iPhone OS has moved between RAM and disk space.

What's New in Version 3.2

Supports showing cpu usage for 3 cores (iPad Air 2 and later).
Adds support for IPv6 network addresses.
Updated for iOS 9. Permissions to access the processes list was removed in iOS 9.

Customer Reviews


I reverted to using an older backup version when they removed the memory refresh feature, then I read the review that stated the memory issue was now fixed. Big mistake. This app is totally worthless - I'll be deleting this and reinstalling my old backup version that actually frees up memory.

It's fixed and not fixed

Works great on my iPad 3, won't work on my iPhone. Would be great to get rid of process tab


Newest version works with my iPhone 6. My iPhone wasn't the same without it.
