12 屏 · 健康与医疗A sleep app that shows its working
Twelve screens of a sleep app built on two stored numbers, a nightly need and fourteen nights, with every bedtime, alarm window, score and trend on every screen derived from those rather than asserted beside them.
设计系统加上全部 12 屏，一条提示词全带走。如果只要其中一屏，每一屏也都有自己的免费页面。
设计系统
随套装附带的一个文件。每一屏都把这些数值写在自己里面，好让它能被单独取走；构建会拒绝任何画出这个文件未命名颜色的屏幕。

流程
按人们遇到它们的先后排列。这是应用自身的顺序，不是一份分类清单。
Setting up
3Three screens to get one number, the amount of sleep this person actually needs, without asking for an account first.
Going to bed
4The evening half of the app. Everything here answers one question, which is what time to put the phone down tonight.
Waking up
2What the night actually was, and the arithmetic behind the number rather than the number on its own.
Keeping it up
3The long view, the upgrade, and the settings that change what every other screen says.
