Being builtTheme 3: Body and head
Four Hours Fine
A sleep experiment on one person: me
A native SwiftUI iPhone app for an N=1 experiment: two weeks of short nights, then two weeks of full ones, with morning and evening check-ins of 10–30 seconds. Built so far: the home screen, sleep entry with a custom time wheel and a night band drawn live, the morning check-in, and a dev panel that fakes any hour or experiment day. The evening check-in, the analysis dashboard and sync exist only in the spec.
Detail
The last rule of the spec governs every feature: nothing gets added unless it helps answer what happens to me on different amounts of sleep.
