I'm Federico Infelici, the developer of Revs and the Quits Mac apps.
Revs shows CPU, memory, disk, network, temperature and battery readings in the Mac menu bar. You can enable and reorder its six modules and choose numbers or graphs. Clicking a reading opens its detail panel.
Temperature readings and fan controls require a privileged helper. The other monitoring modules work without that helper. Revs requires macOS 14 or later.
Revs costs €9.99 once on the Quits website. A license covers five active Macs, updates are included, and purchases have a 30-day refund policy. Readings stay on the Mac; the app has no analytics and contacts Quits for licensing and updates.
The official page includes an interactive browser simulation using sample data. That simulation is not an installable trial.
