Offline Mode
Route 66 works without cell signal
What It Is
Offline Mode is a Progressive Web App (PWA) feature that automatically caches Route 66 content so the app works perfectly even when you don't have cell signal. As you travel, the app automatically pre-downloads the next 50-100 miles of route content, including maps, audio stories, POI information, and sponsor offers.
Whether you're driving through remote deserts, mountain passes, or rural areas with dead zones, Route 66 app stays with you.
How It Works
App Installs as PWA
When you install the Route 66 PWA on your phone, it downloads a service worker—a background technology that manages offline functionality.
Automatic Pre-Caching
Your current location is tracked, and the app automatically pre-downloads content for the next 50-100 miles of your route.
Smart Cache Management
As you drive, old content behind you is removed to save storage. New content ahead is continuously loaded when connected.
Works Without Signal
If you enter an area without cell signal, the app seamlessly switches to cached content with no interruption.
Automatic Re-Sync
When you reconnect to cell service, the app automatically syncs your activity (ratings, tips, achievements) with our servers.
