# The App — Overview

PriceOS is the software layer of Price Discussion — the app collectors and artists actually live in. It is built like an operating system for one obsession: watching a community discuss art through prices. This section documents its surfaces; each page below goes one level deeper.

## The map

- **[The Shell](/docs/app/the-shell)** — everything persistent: the Tape, the navbar, the footer and its easter eggs, the installable app, colorways.
- **[Projects & Minting](/docs/app/projects-and-minting)** — the Project page: the mint flow in the UI, live presence, traits, the Genome, milestones, and each Project's own color.
- **[Outputs](/docs/app/outputs)** — the individual artwork: live on-chain rendering, attributes and rarity, the action row, and the ASCII backup.
- **[Identity & Profiles](/docs/app/identity-and-profiles)** — @names, PriceSprites, profile pages, Showcase, and the Collected / Starred / Wishlist / Albums system.
- **[Collector Tools](/docs/app/collector-tools)** — the OS-tools layer: To-Dos, Notes, the Cart, the Bench, the Calc, the Calendar, Workflows, and Portfolio.
- **[The Spell Book](/docs/app/spell-book)** — pill-toggleable view modifiers and the platform's stranger surfaces.
- **[Pings](/docs/pings/overview)** — the notification system: what fires, what you control, and how pings reach your devices.
- **[Stickers ⊞](/docs/stickers/overview)** — the second economy: sealed sheets, the peel, the binder, and a marketplace of its own.
- **[Achievements](/docs/app/achievements)** — the unlock system across thirteen categories.
- **[Discovery](/docs/app/discovery)** — search, the home surfaces, feeds, and PriceRank.
- **[Composer ⊚](/docs/composer)** — the visual query builder: compose a question about the whole catalog, watch it answer live, save it as a Program.
- **[The Factions](/docs/factions)** — the color war: allegiance, the Sigil, the Marginalia, sieges and the Book of Conquests.
- **[Cartography ◫](/docs/cartography)** — the living map of the whole platform: territories, inhabitants, and market events in real time.
- **[The Rewind ◄](/docs/rewind)** — the whole-OS time scrubber: browse PD as it stood on any past PriceDay.
- **[The Dispatch ❡](/docs/dispatch)** — the morning paper: yesterday on the record, printed daily, archived forever.
- **[Settings & Display](/docs/app/settings-and-display)** — MY PD: colorways, display modes, and per-surface controls.

## Design language, briefly

PriceOS is mobile-first, typographic, and monochrome-leaning: Rubik Mono One display type, Inter body text, and a fixed vocabulary of Courier-rendered Unicode glyphs instead of icon fonts — every glyph in the app means exactly one thing, everywhere it appears. Each page carries a color: the home page wears the **Mood Ring** (a generative color that changes daily), every Project page wears its artist's color, every profile wears its owner's, and the whole system yields to whichever colorway you pick in [settings](/docs/app/settings-and-display).

## One principle worth knowing

**Always feel moving forward.** Anything asynchronous — a mint, a fetch, a reveal — shows continuous motion from the instant it starts until it resolves. If the UI looks frozen, that's a bug, not a style.
