### 1/5 — ! This feature, the Process Monitor, no longer supported!!

*2020-05-24, version 4.8*

I paid for this app and it doesn’t work!

### 5/5 — Very complete status monitor

*2019-03-01, version 4.8*

Has just what you need! Perfect for discovering all the details of your iDevice on a sleepless night,

### 5/5 — Good app, insight into phone inner workings

*2018-01-27, version 4.8*

I have had this app for years; it’s a great way to see what your iPhone is doing and how it’s behaving, a lot of info in one place highly recommended.

### 5/5 — Excellent App since around 2009

*2016-01-16, version 4.7.1*

I have it running on my iPhone 4s & 6 and iPad 1, 2 & 3. Support Team is one of the best of all of the Apps I ever used on both mobile & Mac OSX.

### 5/5 — Great app for checking what's running

*2014-12-07, version 3.9.2*

Ever wondered what apps are running in the background or how much free memory is available or maybe how long it's been since you restarted?  This app will tell you all that and more.  Latest version fixed the device info crash, so it works great again.

### 4/5 — Handy app

*2014-10-29*

This is a well laid out neat little app to show system stats including uptime.  Very handy to debug problems. The current version crashes when device info is tapped, otherwise a great app.

### 1/5 — Nonfunctional

*2014-10-08, version 3.8.2*

I just downloaded this.... All it seems able to is crash.  Tried many times including reboots.

### 4/5 — Good App

*2011-05-18, version 3.0.1*

I like the app. I've been looking for an app that would keep a log of the date and time of each power up (and down, if possible). This app comes very close to that as it keeps a history of boot date and time. It would be 5 star for me it it had a history of power up date and time. An additional bonus would be able to add a date and time history log of user bookmarked processes.

### 5/5 — Awesome utility!

*2010-10-02, version 0*

Great job! SysStats Monitor is now my favorite system utility. Have been fed up with lack of updates for iStat and went looking for an option. 

Sweet interface, outstanding information content. Have really been wanting the 'uptime' feature, thanks for including. The boot history is a nice feature, too.  Love the dynamic graphs, especially the memory pie chart.

### 2/5 — No individual process stats :(

*2010-09-15*

I bought this because my iPhone runs hot and battery expires in a few hours.  I wanted to know what app is killing my battery.  This App confirms that my CPU is running at over 90%, but gives no clue as to which process is causing this.  This happens to my iPhone even when all apps have been closed, and only since I installed OS4.1
This App was not helpful :(
Individual process CPU usage please.
