GPSpedia is a Progressive Web App (PWA). Installing it adds an icon to your device’s home screen and allows the app to run in a dedicated window without browser navigation bars — similar to a native app. A service worker also caches key resources so the app remains usable when your connection is intermittent.
PWA installation is entirely optional. GPSpedia works in any modern browser without installation. Install it only if you prefer the full-screen experience or need reliable offline access.
Installing on Android (Chrome)
Open GPSpedia in Chrome
Navigate to the GPSpedia URL in Google Chrome on your Android device.
Tap the Install button
When Chrome detects that the app meets PWA installability criteria, an Instalar button appears in the header. Tap it.If the button is not visible, you can also tap the three-dot menu in Chrome and select Add to Home Screen.
Confirm the installation prompt
Chrome displays a native install prompt. Tap Install (or Add) to confirm. The app icon is added to your home screen.
Launch from the home screen
Tap the GPSpedia icon on your home screen. The app opens in standalone mode — no address bar or browser tabs.
Installing on iOS (Safari)
Open GPSpedia in Safari
Navigate to the GPSpedia URL in Safari on your iPhone or iPad. The browser-triggered install prompt is not available on iOS — you must use the Share sheet instead.
Open the Share sheet
Tap the Share icon (the box with an arrow pointing up) in the Safari toolbar.
Tap Add to Home Screen
Scroll through the Share sheet options and tap Add to Home Screen.
Confirm
Edit the name if desired, then tap Add in the top-right corner. The app icon appears on your home screen.
Launch from the home screen
Tap the icon to open GPSpedia. It runs in fullscreen mode without Safari’s browser chrome.
Offline behavior
Once installed (or after your first visit), GPSpedia’s service worker caches the application shell and static resources in the background. This means:
- The app loads even when you have no internet connection.
- Previously viewed records may be available from cache.
- New records and real-time data require a connection to load.
The service worker is registered automatically when you visit the site — no manual action is required.
Standalone mode
When launched from the home screen, GPSpedia runs in standalone mode. There is no browser address bar, no tab strip, and no navigation buttons from the browser UI. Back navigation is handled entirely within the app (see Browsing the catalog for details on back navigation behavior).
On mobile, you can refresh the app by pulling down from the top of the screen. Swipe down slowly until you have pulled more than roughly 150 px, then release. The page reloads and fetches the latest records. This gesture only works when you are already scrolled to the very top of the screen.
