The shell, annotated: the navbar with search, your sprite and the connect surface; the Tape ticker; the page content that swaps beneath the persistent chrome; and the three-row footer with the system readouts, the easter-egg row, and the links row.

--- title: "The App — The Shell" description: "PriceOS's persistent layer: the Tape ticker, the navbar, the footer's live readouts and easter eggs, the installable PWA, and the colorway system." category: "app" keywords: ["shell", "tape", "pwa", "footer", "colorways"] last_updated: "2026-07-20" --- # The App — The Shell The shell is everything that persists while pages change underneath it. PriceOS navigates like a native app — the chrome, the painted background, and the live layers stay put; only the page content swaps. - **①︎ The navbar** — search, your PriceSprite, and the connect surface. It fades with scroll and returns on demand. - **②︎ The Tape** — the live ticker: ✦ collected · ✹ listed · ✶ offer · ✸ transfer, each with its actor's @name. - **③︎ The page** — the only thing that swaps as you navigate; the chrome and painted background stay put. - **④︎ The footer** — the system row (tap the version for the changelog), the easter-egg row (❡ [Dispatch](/docs/dispatch) · ⌬ Mood Ring · Today's Stars), and the links row. ## The Tape The persistent live ticker running through the app chrome: mints, sales, listings, offers, and transfers as they happen, each wearing its canonical glyph (✦ collected, ✹ listed, ✶ offer, ✸ transfer) and its actor's @name. The Tape is the platform's pulse — the discussion, scrolling by. ## The navbar Navigation, global search, your PriceSprite, and the connect surface. It fades with scroll and returns on demand, and a Back Button Mode replaces it with a single persistent back arrow for collectors who navigate that way. ## The footer Deliberately under-used real estate, currently three rows: - **System row** — the PriceOS version (tap for the changelog), connection status, live gas in gwei, and the current Ethereum block number. - **Easter-egg row** — [the Dispatch](/docs/dispatch) (❡), the **Mood Ring** (⌬), today's platform-wide generative color, and **Today's Stars** (☉ ☽ ↑), the natal sky over Montreal at today's UTC midnight; every Output minted today is born under it. - **Links row** — About, Discord, these Docs, Support, Studio. ## The installable app PriceOS is a PWA: installable to the home screen on iOS and Android, with an offline fallback served by a hand-written network-first service worker, pull-to-refresh in standalone mode, a dynamic favicon that repaints with the live colorway, and native push notifications for [Pings](/docs/pings/overview) on devices that allow it. ## Colorways The whole app is painted through one variable system. Defaults are per-page — home wears the daily Mood Ring, Projects wear their artist's color, profiles wear their owner's — and an explicit pick in [settings](/docs/app/settings-and-display) (Light, Dark, Orange, Blueberry, Cherry, Hash Synesthesia, Haze, or a fully custom color) wins everywhere, painted before first frame so there is never a flash. These docs default to Dark and carry the same picker. ## The Command Stone ⌘ **How:** Triple-tap the background of any page. Triple-tap the background of any page and PD's command line rises — find anything, ask the ledger a question, etch a to-do, cast a spell by name, or summon a widget. It has [its own page](/docs/command-stone). ## Ambient Strip An optional dimming layer for late-night browsing that pulls the whole interface down to ember levels without changing its layout. ## Further reading - [Settings & Display](/docs/app/settings-and-display) - [Pings](/docs/pings/overview) - [Discovery](/docs/app/discovery)
