Activity Monitor shows this second. Warashi remembers. It sits quietly in your menu bar (and beside the notch), records CPU, memory, GPU, power, temperature and what every app costs, and keeps up to a year of history on your Mac. Look back at what slowed it down, see what each app costs per hour of use, get told once when something runs away, and let the Upgrade Advisor size your next Mac from your own usage. Native, private, and light: 0.18% CPU in the background. Free during the beta.

Could you build this?
Partial The UI and storage are vibe-codeable, but accurate per-app power and cost attribution with GPU and temperature sensing depends on macOS private or low-level system APIs that require deep platform expertise.
What it would actually take: Build a native Swift menu-bar app with a time-series store, polling IOKit/SMC and mach APIs for CPU, GPU, memory, power, and thermals. The hard part is reliably attributing energy and cost to individual apps, which needs careful calibration against Apple's own energy metrics and possibly undocumented interfaces. This needs experienced macOS systems engineering.
