True Offline Architecture
Every feature works without cell signal. Period.
Most hunting apps show you a blank screen when you lose signal. BKM Outdoors is built offline-first — every byte of data is stored locally in IndexedDB on your device. The service worker caches the app shell and map tiles for instant loading. Chat messages queue when offline and send when you're back in range. This isn't an afterthought — it's the architecture.
How It Works
The entire app installs as a PWA (Progressive Web App) on your device.
A service worker caches the app shell, JavaScript, CSS, and map tiles.
All data (waypoints, observations, trails, boundaries, tracks, hunt logs) lives in IndexedDB.
When you lose signal, everything keeps working normally.
When signal returns, queued chat messages and location pings sync automatically.

Why BKM Does This Better
Other apps treat offline as a premium add-on. BKM is built offline-first from the ground up — every feature works without signal, not just maps.
