12 screens · Cars and ownershipAn electric car, and the arithmetic of living with one
Twelve screens of an electric vehicle companion app built on the two numbers that actually govern the thing, the energy in the battery and the miles it buys, with every range figure, charge time, tariff and session cost 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.
The car
4What the car is doing right now. State of charge, the session running on it, the cabin, and what the battery is actually buying in miles.
Going somewhere
4A long trip is the one thing an electric car makes you think about. Four screens that turn a distance into a route with stops on it.
Living with it
4The parts that repeat. What charging has cost, when it should happen, what the car needs looking at, and who is allowed to drive it.
