Name: Heat Watch Lite
Author: osi.vibe.code

Is your Mac running hot or busy?

macOS - Coming Soon

macOS 13+

Trouble with Heat Watch Lite? Get support

Is your Mac hot, or just busy? Heat Watch Lite sits in the menu bar with CPU and GPU use at a glance, tells you in plain language how macOS is handling the heat, and taps you on the shoulder when the Mac stays busy for a while, starts slowing itself down to cool off, or runs low on memory.

Coming soon to the Mac App Store.

Both editions side by side, with what each one can do: the Heat Watch editions.

Features

History Charts of CPU, GPU and the heat state from 15 minutes to 24 hours, a log of recent alerts, and CSV export.
Desktop panel A floating set of live tiles you can place anywhere.
