What is it

VitalSigns 3 is a system monitor for macOS Big Sur, featuring a clean and minimalist style that is extremely readable and easy on the eyes.

A bit of history

VitalSigns has been around since 2015. The app initially worked as a small widget in the macOS Notification Center.

When Apple released macOS Big Sur, it dramatically changed the way widgets work, which made it impossible to update the widget contents in real-time. In order to get the app working on Big Sur, I had to re-write the code almost from scratch, and also move it to the macOS status bar.

The old version for macOS Catalina and earlier is still available, although it's no longer supported.
