Sophia's Future Doctor Club

Weekly activities and a journal for kids interested in medicine. Everything stays on the device.

I built this for a kid who wants to become a doctor, with activities she could do each week and a place to write about them.

Each week includes activities in science, math, reading, writing, and service. Kids can write Club Notes, earn XP and badges, swap activities, or add their own. There are no accounts or ads, and data is stored locally.

Built with

Expo / React Native (TypeScript) · expo-sqlite (local-only) · expo-notifications · Expo Router · EAS Build / App Store

Technical challenges

01
Deterministic weekly mission selection: seeded RNG, rank-gated pools, difficulty budgets, and an eight-week template exclusion to avoid repeating recent activities.
02
Versioned SQLite migrations and week-plan invalidation when the catalog or rank at selection changes – without an ORM or a backend.
03
Shipping a privacy-first kids' app: everything stays on device; notifications only after the user opts in.

Role

I designed, built, and released it.
