Glance Mobile

Expo companion app for Glance G2 — a personal dashboard aggregator for Even Realities G2 smart glasses.

This mobile app is the data source. It reads Apple Calendar, fetches weather/finance/RSS from public APIs, builds a card snapshot, and pushes it to a glance-backend server every 60 seconds. The glance-g2 app on the glasses streams from that backend via SSE and rotates through the cards.

Features

• Meeting card — nearest non-all-day calendar event in next 24h
• Weather card — OpenWeather by city (user-provided API key)
• Finance card — Alpha Vantage GLOBAL_QUOTE (user-provided key)
• RSS headlines — minimal regex-based parser, no deps
• Battery / activity cards — placeholders for future HealthKit integration
• Dark-themed settings UI, card selector, force-refresh button
