Mobile & offline use

VAIXR is a Progressive Web App (PWA). That means you can install it on your phone, tablet, or laptop without going through an app store, and part of the functionality keeps working without an internet connection.

Installing VAIXR

Open VAIXR in your device's browser and choose "Add to Home screen" (Android/Chrome) or "Add to Home Screen" (iOS/Safari) from the share or menu icon. The app then appears as an icon on your home screen and launches in its own window, without a browser bar.

Offline tagging

During a match, the connection on the sideline isn't always reliable. Tags you create while offline are stored locally in the browser (IndexedDB) and marked as pending sync. As soon as your device reconnects, the Background Sync API automatically sends the pending tags to the server — you don't have to do anything yourself.

Live tagger and offline

The standalone live tagger (`/live-tagger` and `/tagger`) is built for real-time use during a match and works best with an active connection, since tags are broadcast instantly to every connected analyst via SignalR. During a brief connection drop, tags here also fall back to the offline queue.
