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.

Both free. Requires macOS 26 Tahoe on Apple silicon or Intel. GitHub download: version 1.1.1, 2.3 MB.

The Puls panel opened from the menu bar, with tiles for CPU, graphics, memory, network, disk, sensors and battery

Every part of your Mac, one click deeper.

Each tile opens a detail view with history, the numbers behind it and what they mean.

The CPU detail view with total load, per-core bars and system load

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.
