Your Mac, at a glance.
Puls sits in your menu bar and shows what your Mac is doing right now: processor, graphics, memory, network, disk, thermals and battery. One click opens the details.
Every part of your Mac, one click deeper.
Each tile opens a detail view with history, the numbers behind it and what they mean.






Made to stay out of the way.
Light on your Mac
Puls measures every two seconds and uses well under one percent of a single core while doing it.
Private by design
No account, no analytics, no ads. Your readings never leave your Mac.
At home on Tahoe
Built with SwiftUI and Liquid Glass, in English and German, with light and dark mode.
Two ways to get Puls.
Both are free. The App Store version runs in Apple's sandbox, which blocks access to sensors and other apps, so it shows a little less.
