You can use DevPath in a browser or install it on supported devices. Installation adds an app icon and a standalone window. The available option depends on your browser.
Android and desktop
Use your browser menu: “Install app” or “Add to Home screen.” The button below appears when your browser offers an installation prompt.
iPhone and iPad
Open the site in Safari. Choose Share → Add to Home Screen. If offered, enable “Open as Web App,” then choose Add.
What works offline?
A bilingual offline screen is available after the service worker installs. Lessons, login, progress, private notes, and quiz answers require a connection. Offline submissions are not queued, synced, or graded. Reconnect and check the saved result; only a server confirmation means a save succeeded.
Opening a local site on your phone
127.0.0.1 on a phone means the phone itself, not your computer. Use the hosted site's HTTPS address. An ordinary local-network HTTP address may not support service workers or installation. Do not expose your development server publicly.
Updates
Close all DevPath windows and reopen to activate an available app update. We do not force an update in the middle of a quiz.
