12 screens · Health and medicalA 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.
The design system and all 12 screens in one prompt. Each screen is also on its own page, free, if you only want one.
Design system
One file, shipped with the set. Every screen declares these values inline so it can be lifted out on its own, and the build refuses a screen that paints a colour this file does not name.

The flow
In the order somebody meets them. This is the app's own sequence, not a list of categories.
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.
