Install on iPhone / iPad

Safari’s Add to Home Screen is the installable iPhone/iPad app — icon, fullscreen, offline. No App Store binary.

iPhone / iPad

Add to Home Screen

This is how you install Lingo as a real iPhone / iPad app without the App Store: icon on the Home Screen, fullscreen (no Safari chrome), and offline after one cache warm.

  1. Open Lingo in Safari (not Chrome or Firefox). Use an https:// link — not Mac localhost.
  2. Tap the Share button (square with an upward arrow). On iPad it sits in the toolbar; on iPhone it is often at the bottom of Safari.
  3. Scroll the sheet and tap Add to Home Screen, then Add. On iPad you may need to swipe the action list to find it.
  4. Open the new Lingo icon (fullscreen, no Safari chrome), then tap Cache main screens now below once while online — or wait for the quiet daily warm.
  5. Optional check: turn on Airplane Mode and open Home, Path, and Dict.

Android

Chrome → menu (⋮) → Install app or Add to Home screen.

From your Mac

iPhone / iPad cannot install from localhost. On the Mac run npm run deploy:check, then npm run deploy (needs npx vercel login once). Or import the GitHub repo at vercel.com/new. Open the HTTPS URL in Safari → Add to Home Screen. Full steps: docs/install.md.

You're on localhost. Deploy with npm run deploy, then open the public URL on your iPad.

Offline checklist

  • Install from Safari over HTTPS
  • Cache once (button below) — Home, Path, Review, Scenes, Decode, Basics, Grammar, Words, Dict, Settings, plus lesson pages and RSC shells for in-app navigation
  • Progress saves automatically on this device (IndexedDB). Use Settings for file backup or cloud sync.
  • Dictionary pack caches after first load / warm

Not on the App Store

Apple does not list this web app in the App Store. Add to Home Screen from Safari on an https:// deploy is the supported install. That gives a real icon, standalone display, and offline use after you cache once.

What needs network

Cloud sync and account login need a connection. Pronunciation uses your device’s German voice. After an app update, open Lingo once online (hard-refresh if a page looks stuck).
