Install the App in 3 Steps
Android users download the APK directly from the d300m site — no app store needed. Before you tap install, go to your phone's Settings, open Security or Privacy, and switch on 'Install from unknown sources' for your browser. iOS users find the app through the App Store link on the d300m site; no settings change is needed on iPhone. The whole process
takes under two minutes on a standard mobile connection. Once installed, sign in with your existing d300m account or open a new one from the app's welcome screen — your wallet balance and account history carry over immediately.
- Download the APK or App Store Link — Tap the download button on the d300m site. Android gets an APK file; iOS opens the App Store listing directly.
- Allow Install from Unknown Sources (Android only) — Go to Settings → Security → enable 'Install unknown apps' for your browser app. This is a one-time step.
- Open and Sign In — Launch the app, enter your d300m account credentials, and enable fingerprint login when prompted. Your lobby loads within seconds.
