Get the DuelDB app

Installing

The app is new and not yet signed by Microsoft, Apple or Google, so the first start asks you to confirm it.

Windows

1. Open DuelDB-Windows-Setup.exe.
2. If Windows shows "Windows protected your PC", click More info, then Run anyway.
3. DuelDB is now in your Start menu.

Installed DuelDB from Chrome or Edge before? That is the old version, which the app replaces. Remove it in Settings → Apps → Installed apps: search DuelDB and uninstall the one not marked dueldb (Chrome's says Google\Chrome).

Mac

1. Open DuelDB-Mac.dmg and drag DuelDB to Applications.
2. Open DuelDB. macOS says it cannot check the app: click Done.
3. Go to System Settings → Privacy & Security, scroll down and click Open Anyway next to DuelDB. You do this only once.

Android

1. Download DuelDB-Android.apk and open it.
2. Android asks if your browser may install apps: tap Settings, turn on Allow from this source and go back.
3. Tap Install. DuelDB is now with your other apps.

iPhone & iPad

1. Open dueldb.com in Safari.
2. Tap the Share button (the square with the arrow).
3. Tap Add to Home Screen, then Add.
4. DuelDB is now on your home screen and opens full screen, like an app.
