Project Overview
LifeCountDown is a React Native and Expo application for displaying life and time countdowns. A published browser version is available.
Problem / Context
The app presents time visually, with an onboarding flow and countdown-oriented interface.
Key Features
- Onboarding and a live countdown interface.
- React Native mobile and browser experiences.
- Local settings and Firebase-backed content.
- English and Chinese interfaces.
- AI-assisted content integrations in the source implementation.
Tech Stack
Architecture
Shared React Native code uses Expo and React Native Web for the browser experience. Firebase provides content integration; local state uses AsyncStorage. The source also includes native notification and Android widget integrations.
Technical Challenges
A shared interface still has platform-specific capabilities. Native widgets and notifications should not be assumed to work identically in the browser.
Engineering Decisions / Trade-offs
Expo supports a browser entry point without replacing the mobile app. A public showcase should prioritize the countdown and sample content; hosted AI use needs separate credential and usage controls.

Results
The existing Vercel site returned HTTP 200 and rendered onboarding during verification. AI requests, cloud writes, and native-only features were not exercised.
