*** UPDATE regarding CPU usage for Android Oreo and up ***
So Android Oreo added yet another restriction disallowing access to the CPU usage stats. Thus, CPU usages unfortunately won't work on devices with Android Oreo. I have released a beta version of the app accommodating the rooted Android Oreo devices where it should work just fine. Do post feedback or send me an email if the BETA version doesn't work on your rooted Oreo device. Thanks!
*** END UPDATE ***
*** UPDATE regarding Active Processes monitor on Android Nougat and up ***
I have released a beta version of the app with Active Processes monitor working on devices with ROOT access. You'd need to become a beta tester in order to install it. It may be a bit buggy. Any feedback is appreciated, thanks!
*** END UPDATE ***
*** NOTE*** 
Some features of Simple System Monitor does not work properly with android version 6.0 and up because of the underlying system changes.
Also, as of Android Nougat, Active Processes tab will show only one app, Simple System Monitor itself. This is because Nougat has restricted access to /proc directory where information about running processes are retrieved from. Please bug Google about this issue instead of me :)
*** END NOTE***

    Changing the update interval changes the output, like, setting it to 10 seconds, the maximum CPU usage will never go above 10%, but setting it to 5 seconds, the maximum will never go above 50%. It's like it was only tested for 1 second intervals.

    A lot of the functionality is not activated. For Active Processes - which I am sure users want to see - it wants the user to connect to computer via usb and run adb shell commands to grant it permission! So the assumption is users know how to run shell commands on computers...etc...I might as well enter Developer Options and tap 7 times...display is clutterfree, otherwise...for what its worth

    Hi Pal, App is great, i wont want to reduce any rating because it was working perfectly on my phone but i am getting this error for past 1 year, I send it from the application, could you please check that java.lang.NoSuchMethodError: No direct method (Ljava/io/File;)V in class Landroid/os/FileObserver; or its super classes (declaration of 'android.os.FileObserver' appears in /system/framework/framework.jar If you know some workaround to set root directory please share that too.

    false advertising, they say floating mode, but guess what there is no floating mode, you guys dropped the ball on this one

    Excellent! Could it show disk read/write per proccess so we could determine offending ones and have a chance to determine if we could stop them? Sometimes, some weird proccess reads a few gigabytes what causes severe lag.. I am almost rooting my phone to prevent so much weirdness messing things up.. Thx!!!

    Great app, but I have a little suggestion: can you please make a pop up? So that I can monitor system resource usage when not in the app? It will be similar to YouTube's picture in picture mode.

    Excellent , All round very polished, Does exactly as described , no BS. Hard to find such nice garbage free apps these days, Other App developer's take note, this is how apps should be, Thanks for the great work developer! Coffee Inbound.

    The best feature of this App is it shows you a graphical history of any measurement up to last 19 minutes, and that is an important thing for making reviews.

    Overlay is poor and you can't even overlay individual cores or show freq. Also asked for Root without explaining why?

    I've been using and developing Android for years, and I've never seen this app! Very useful, especially the floating graphs. I use AIDE to prototype on my device itself, and this compliments it very well. I want to run it through its paces, but I'll buy the developer a pot of coffee if it works as well as I think it will. Thanks....
