Simple System Monitor Descriptions

*** NOTE***
Some features of Simple System Monitor does not work properly with Marshmallow (Android 6.0) because of the underlying system changes.
*** 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.

• CPU usage and frequencies for each core
• Total CPU usage and average frequency
• CPU frequency graph for each core
• Time spent on each CPU frequency state
• GPU usage and frequency*
• RAM usage and ability to clear RAM
• Network activity
• Disk I/O activity (internal and external)
• Test disks' read/write speeds (internal or external)
• Simple file browser that shows disk space usages using a pie chart (root not supported, yet)
• Cache cleaner (requires ROOT)
• View list of active apps and processes and their CPU usage, RAM usage, network activity, PID and UID.
• Kill processes as ROOT (only works on rooted devices)**
• 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

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

*Only Adreno GPUs are supported 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 supported.

**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 Any feedback is much appreciated.
