SystemWoe vs iStat Menus
iStat Menus (Bjango) is the classic menu-bar sensor suite — GPU, CPU, memory, network, disk, top processes, hardware detail. SystemWoe stays situation- and action-first, not a sensor zoo.
Verdict
Choose iStat Menus for dense hardware and weather-class menu-bar dashboards. Choose SystemWoe for “what on earth is my disk doing?” — named culprits, knowledge, and safe free — with Pro thermals as package power / pressure, not fan-RPM grids.

Pick iStat Menus when
- You want fans, sensors, and dense menu-bar charts
- Hardware monitoring is the primary job
- You already know every process basename by heart
Pick SystemWoe when
- Mystery load needs a plain-English answer
- You need I/O causes, knowledge, and keep-guards
- Developer Docker / Spotlight / TM narratives matter
SystemWoe Pro Thermals & Power is explicitly not an iStat replacement (°C die sensors, fan RPM grids). Pricing notes are approximate.
