What you get
- Standalone window. No browser chrome, no tabs, no distractions. Just your learning.
- Offline access. Previously cached lessons, local flashcards, and progress remain available offline. Visit lessons and initialize supported local runtimes while online first. Web previews, AI, sync, and uncached content require a connection.
- Quick launch. App icon in your taskbar, dock, or home screen. One tap to start learning.
- Auto-updates. New versions download while online. When an update is ready, save your work and use the restart prompt. Offline devices keep the cached version.
- Local data. Your progress, settings, and flashcards are stored on your device. No account needed.
How it works
DURA is built as a Progressive Web App (PWA) — a web standard supported by all major browsers and operating systems. PWAs use service workers for offline caching, the Web App Manifest for installation metadata, and IndexedDB for local data storage. No native code, no app store fees, no platform lock-in.
Standards: W3C Web App Manifest, W3C Service Workers, WHATWG IndexedDB, W3C Web Push API.
