Taskglass is a native Mac app that shows what's slowing, heating or draining your Mac, and explains it in plain English.
Who it's for: anyone who has opened Activity Monitor, seen kernel_task or WindowServer at the top, and had no idea what to do about it.
What it does: - Groups helper processes under their app (Chrome is one row, not 40) - Explains 200+ macOS processes and whether they're safe to quit - Keeps 30 days of CPU, memory, heat and power history - Shows battery drain per app in real watts on Apple Silicon
What's new: version 1.0.1 just shipped, in 9 languages.
Native Swift, 6 MB, no account and no tracking. One-time purchase, no subscription.
