What It Does
Everything you need to know about your system, nothing you don't.
CPU usage, CPU temp, GPU usage, GPU temp — four animated arc gauges with 300-degree sweep. Color shifts from white to orange to red as temps climb.
90-point rolling graphs under each gauge. Plus a full 3600-point history window you can export as PNG whenever you need proof your GPU hit 90 degrees.
Per-metric thresholds with tray notifications. 5-minute cooldown so it's not nagging you. Triggers after 10 consecutive readings, not random spikes.
Dark, Synthwave, Dracula, Nord, AMOLED, and more. Switch from the settings menu. Because a system monitor should look as good as your desktop.
Optional CSV or NDJSON logging with configurable retention. Auto-flushes every 60 seconds. Great for tracking thermals over time or proving your case for a new cooler.
Double-click to snap to the top edge as a full-width bar. Or switch to compact mode — one slim line with all key stats. Adjustable opacity, always-on-top, position memory.
Optional per-core CPU breakdown and fan RPM display. Network upload/download in Mbps. Battery gauge for laptops. NVMe temps in the status bar.
Save and load entire configurations as presets. Theme, gauges, opacity, refresh rate, alerts — everything. Switch between setups instantly.
First launch creates a desktop shortcut and enables autostart. AppImage on Linux, runs from source on Windows/macOS. Detects your GPU automatically.
