The idea

I built this iPhone app for the owners of Hype Room, a sneaker and streetwear store. Shoppers can enter a free weekly draw, browse the catalog and request a pair to pick up in store.

What I built

The Expo app has five tabs. A shared Catalog interface currently serves sample data and can accept live inventory without changing the screens. One app-wide clock keeps every countdown in sync.

Draw entries, holds, saved items and shoe size stay on the phone in expo-sqlite’s key-value store. The demo has no backend and does not process payments.

The hard parts

01 Weekly draws across daylight saving changes

Each weekly draw gets a dated ID calculated from a fixed starting week. The calendar handles daylight saving changes and keeps entries tied to their week. A test checks every hour of three weeks, including both clock changes, to ensure two draws never open at once.

Where in the code: src/data/__tests__/drops.test.ts
02 Readable hold codes

Hold codes use a 31-character alphabet that excludes 0, O, 1, I and L, making them easier to read at the counter. A tested pure helper sets each hold’s 48-hour expiry.

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

The app includes an Official Rules screen and states on each draw page that entry is free and no purchase is necessary.
