An iPhone app for Hype Room, a sneaker and streetwear store: a free weekly draw, the store catalog, and in-store holds. Pre-launch demo with sample data.

Role: Solo: design and code, for the store owners
Timeline: Jul 2026 to now
Stack: TypeScript, Expo, React Native, Expo Router, SQLite, Jest

In development. Pre-launch demo with sample data. Not on the App Store. Status checked Oct 15, 2026.

By the numbers

tests in 8 suites

it() and test() calls in src/lib/__tests__ and src/data/__tests__, plus 2 rows from describe.each; matches the README. Counted Oct 5, 2026.

168

hours checked in each of 3 weeks of the draw calendar

the hourly sweep in drops.test.ts over a normal week and the two weeks with a DST change. Counted Oct 5, 2026.

48 h

before an in-store hold expires

HOLD_MS in src/lib/pickups.ts, with tests. Counted Oct 5, 2026.

The idea

Hype Room is a sneaker and streetwear store. The owners wanted an iPhone app where shoppers enter a free weekly draw, browse the store, and ask the staff to hold a pair for pickup.

What I built

An Expo app with five tabs. All data goes through one Catalog interface backed by sample data, so live inventory can replace it without changing any screen. One app-wide clock drives every countdown.

Shopper state, such as draw entries, holds, saved items and shoe size, stays on the phone in expo-sqlite’s key-value store. There is no backend yet, and no money moves through the app.

The hard parts

01 A weekly draw calendar that holds across DST

Each weekly draw has a dated id, built from a fixed starting week with calendar math that is safe across daylight saving changes, so an entry never carries into the next week. A test steps through every hour of three weeks, including the weeks when DST ends and starts, and checks that two draws are never open at once.

Where in the code: src/data/__tests__/drops.test.ts
02 Hold codes staff can read

Hold codes use a 31-character alphabet with no 0, O, 1, I or L, so staff can read them at the counter. A pure helper sets the 48-hour expiry, and tests cover it.

Where in the code: src/lib/pickups.ts
03 A free draw with official rules

The draw is free to enter. The app has an Official Rules screen, and the draw pages show a no-purchase-necessary disclosure.
