Architecture

One source of truth. One file for iOS and Android.

Open a screen group and build today. The token architecture underneath is why a rebrand is still one edit six months from now.

Four kit components in the brand blue: a color picker with #155DFC chosen, a table of people with amounts and Paid, Pending and Overdue statuses, a time picker with 10:30 AM selected, and a heatmap of active days reading 58 of 91Four kit components in the brand blue: a color picker with #155DFC chosen, a table of people with amounts and Paid, Pending and Overdue statuses, a time picker with 10:30 AM selected, and a heatmap of active days reading 58 of 91

Tokens

Rebrand in minutes

Change the brand color once. Every component, both platform mirrors, light and dark, follow it. You do not reopen a single screen.
Six app screens from the kit in two rows: an AI chat with a generated hero image, a fitness profile with 382 minutes of weekly activity and personal records, a message thread, a social feed with stories, the order AP 4192 arriving in 12 minutes on a map, and a wallet with a Vault Digital cardSix app screens from the kit in two rows: an AI chat with a generated hero image, a fitness profile with 382 minutes of weekly activity and personal records, a message thread, a social feed with stories, the order AP 4192 arriving in 12 minutes on a map, and a wallet with a Vault Digital card

App examples

App flows for finance, booking, fitness, social, AI, food and tasks, built from the same components and wired to the same tokens.

Platforms

Ship both platforms

Apple and Material conventions live together. No second library, no translation step.

Code handoff

Hand off components, not a spec

Your developer opens the folder for their stack and finds the same components, variants and tokens as in your file.

See Appetite UI Code

Three app screens in a row with the middle one in the other mode: a Product task board with To do cards, a Trips screen with the Lakeside cabin in Ruka and the trips later this year, and a food delivery home with cuisine filters and a Free delivery all week bannerThree app screens in a row with the middle one in the other mode: a Product task board with To do cards, a Trips screen with the Lakeside cabin in Ruka and the trips later this year, and a food delivery home with cuisine filters and a Free delivery all week banner

Dark mode

Dark mode is already drawn

Every component already has it, because color is a token and tokens have two modes.

AI agents

Brief an agent in one file

The Core Skill in the file you buy tells Claude, Cursor and Figma Make which token to use. With Appetite UI Code, your agent builds with the components, in your stack.

How agents use it

Screens

Start at screen level, not at button level.

Complete app screens, wired to your tokens. Open one and keep building.
