About PC Electro Onna-chan Checker
PC Electro Onna‑chan Checker is a casual indie desktop companion that reacts to your computer’s performance. It shows Electro Onna‑chan’s emotions based on CPU/GPU load and battery level, giving a quick visual cue of system activity while you work or game.
The app runs on Windows, offers a mouse‑only option, adjustable text size, Steam achievements, and family‑sharing support. It is single‑player, plays at your own pace, and does not require timed input.
01 / THE GUIDE
Reaction System
Electro Onna‑chan changes expression according to your PC’s usage. When CPU/GPU usage or battery percentage reaches 61 % or higher, she appears extremely overjoyed; between 31 % and 60 % she is having a blast; at 30 % or lower she becomes extremely angry.
These three thresholds provide an at‑a‑glance indication of how hard your system is working, allowing you to monitor performance without opening separate tools.
- Watch the mascot while running demanding software to see real‑time feedback.
- Use the visual cue to decide when to lower graphics settings for smoother performance.
