Mobile Access in Three Steps
There is no APK file to sideload and no app store listing to find — the mobile build lives at OKBT and loads directly in your browser. Open the site on Chrome or Safari, sign into your account, and the interface resizes automatically to your screen. If you want a shortcut on your home screen, use your browser's 'Add to Home Screen'
option: on Android tap the three-dot menu and choose that option; on iOS tap the share icon then 'Add to Home Screen'. That shortcut opens the lobby in a full-screen view without the browser address bar. Account access depends on your region and local law.
- Open the current site — Go to OKBT in your mobile browser. Chrome on Android and Safari on iOS both load the full lobby without extra steps.
- Check browser compatibility — If the lobby does not render correctly, update your browser to its current version. Most display issues on older Android devices come from an outdated Chrome build.
- Sign in securely — Log in with your credentials. On a supported device, enable fingerprint login from your account security settings to skip the password on future visits.
- Add to your home screen — Use your browser's share or menu option to pin the site as a home screen shortcut. This gives you a one-tap path to the lobby without typing the URL each time.
