JD Arena app

🤖 Android

Version 2.1.3 · 3.5 MB · Android 7 or newer

1. Tap Download, then open the file when it finishes.
2. If Android asks, allow your browser to install unknown apps (only this once).
3. Tap Install, open JD Arena and sign in. If Google Play Protect stops it, that's only because the app is new and not from the Play Store:
   • "Play Protect hasn't seen this app" → tap Scan app, wait a few seconds, then Install.
   • "Send app for a security check" → tap Send (or Don't send), then Install.
   • "Unsafe app blocked" → tap More details → Install anyway.
   The app asks for notifications, and (only if you allow it) your rough area for regional stats - never SMS, contacts or accessibility.
4. Allow notifications so room IDs and results reach you.
5. Had the old web version on your home screen? Delete it: long-press the old JD Arena icon → Uninstall (or Remove), so alerts come through the app and not twice.

Already have the app? Download again and tap Update - your account stays signed in.

It's the same JD Arena as the website, so it's always up to date. When a new app version comes out, the app shows an Update now button.
