Simple System Monitor

Simple system monitoring tool

*** UPDATE regarding U usage for Android Oreo and up ***

So Android Oreo added yet another restriction disallowing access to the U usage stats. Thus, U 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 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 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***

Simple System Monitor, as the name suggests, is a clean and simple system monitoring app for your android device. It graphically shows usages of various system components.

Features:

• U usage and frequencies for each core

• Total U usage and average frequency

• U frequency graph for each core

• Time spent on each U frequency state

• GPU usage and frequency*

• RAM usage and ability to clear RAM

• Network activity

• Disk I/O activity (internal and SD card)

• Test disks' read/write speeds (internal or external)

• File browser with for basic operations (copy,cut,delete)

• Cache cleaner (optionally requires ROOT)

• View list of active apps and processes and their U usage, RAM usage, network activity, PID and UID.

• Kill processes as ROOT (only works on rooted devices)**

• View temperatures of all of the thermal zones

• View battery health and temperature

• Ability to keep running in the background despite being swiped away from the recent tasks list

• Floating mode - shows system monitor data on a little floating window on top of other apps

• Dark UI theme

If you see "..." for one or more U frequencies under the U monitor graph, restarting the phone should solve the issue.

*Only Adreno GPUs are ed at the moment. Sometimes the GPU stat information may not be available/accessible in the kernel even if the device has Adreno GPU. In such case, "..." will be displayed instead of a frequency. If you don't see the GPU monitor, then your device's GPU is not ed.

**Using ROOT to kill processes is not recommended and should be used very cautiously. I do not hold any responsibility if something bad happens to your system or device because of it.

If you find a bug, please send me an email at [email protected]. Any is much appreciated.
