Field notes
The page argues that ordinary screen-time totals mix distracting apps with useful tasks such as maps, messages, lecture notes, and calls. Its proposed tracking instead focuses on apps selected by the user, with totals shown for today, the year, and a lifetime view. The page also describes a home-screen display for daily dead time, streak status, and the streak graveyard; the app itself is listed as coming soon.
