"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."

NOTE: Turn on Backward Compatibility (in the Settings app) to get the previous pre-iOS 5.x behavior.

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.

Customer Reviews

Garbage with no support

Used to be good. All the bad reviews you read are true. Stopped functioning and even stopped installing properly. Trouble shot issue thoroughly with Apple. Was told to contact developer. When you contact their support by email only they reply with ONE innane question at a time over weeks and weeks...What phone do you have, What iOS do you have, Is your phone jailbroken, Did you try restarting your phone..... and on and on and on one question at a time forever and ever and ever.....BUT NEVER solving any problem with their app. I would avoid this Developer and any of their Apps at all costs. I finally bought Memory & Disk Scanner Pro. WOW! Many times better than this ever was!

HORRIBLE ! ! ! ! But ! ! ! Look at the end of review !

The newest update deserves NO STARS ! ! ! ! ! It does NOT work !! I thought it was just me until I looked here at the reviews, it’s NOT just me, this app has taken a CRAP ! I had ALL my friends download it because it worked, it works NO MORE ! DON’T download until it is fixed !
I emailed them, they gave me a story about WHY it doesn’t work, they told me to RESTORE the old version from the trash can on the computer, I did that, the old version 3.0 works just fine ! THAT is how you fix the problem if you backed your device up on your computer through iTunes. YAY !

Bad business model

I have never written a review before this but I can't believe you can get this many bad reviews and just go about business like it's all good. I used to use this app when they had a button to dump the memory. Then you took away that but it would still dump. Now that's gone too! Now the app is useless.
