Does IhramOS work without internet connection?

Yes, IhramOS is built with an offline-first architecture specifically because cellular networks become unreliable during Hajj when over two million pilgrims overwhelm local infrastructure. All core features including ritual guidance, the complete dua library with audio playback, tawaf counter, sa'i counter, prayer time calculations, qibla compass, emergency contacts, your medical card, and pilgrimage journal work entirely without internet.

Before your trip, IhramOS prompts you to download all content and offline map tiles while connected to WiFi. This one-time download stores everything locally on your device using an embedded SQLite database. During your pilgrimage, all data reads and writes happen locally first. When connectivity returns, the app automatically syncs pending data in the background.

The only features that require internet are the AI chatbot, live group location sharing, weather updates, and community feed. The SOS emergency button queues an SMS if no data connection is available, sending it automatically when connectivity returns.
