Does ইহরামOS work without internet connection?

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

Before your trip, ইহরামOS 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 হজ্জ, 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 জরুরি button queues an SMS if no data connection is available, sending it automatically when connectivity returns.
