Tabs

CPU Monitor has three tabs:

• Overview
• Per Core
• Details

You can swipe between tabs or tap the tab titles.

Overview Tab

The Overview tab contains two sections:

• CPU Usage
  • Current CPU usage percentage displayed prominently
  • Usage History graph showing a rolling timeline of overall CPU activity
• CPU Information
  • Current usage
  • Number of cores
  • Active cores (cores above a small activity threshold)
  • Average / highest / lowest per-core usage

Per Core Tab

Per Core tab with individual usage graphs for each CPU core

Per Core shows one card per CPU core:

• Core number and current usage percentage
• A mini usage history graph for that core

This view is useful for spotting cores that are consistently busier than others or detecting uneven load distribution.

Details Tab

Details tab with total usage summary and per-core segmented gauges

Details is a compact breakdown view:

• Total Usage card showing overall CPU usage percentage and core count
• Per Core Usage list
  • Each row shows the core number, current usage percentage, and a color-coded segmented gauge that fills based on load

Notes And Limitations

• CPU Monitor reports device-level overall and per-core usage. It does not list per-app or per-process CPU usage.
• Values update continuously while the tool is open.
