What the App Brings You

Our mobile app strips away the browser lag. You get instant notifications when live tables fill up, one-tap deposit via DANA, OVO, GoPay or QRIS, and biometric login so you're in your account in under three seconds. The app also caches your favourite slot rooms and betslips, so you can preview them offline before you tap to play.

BENCHMARKED

App vs Mobile Browser

Load Speed

App loads live tables in 1–2 seconds. Mobile browser takes 4–6 seconds because it has to render the full page each time.

Notifications

App sends push alerts for live tables, slot features and market opens. Browser has no way to notify you when you're not on the page.

Offline Access

App caches your lobby and recent bets so you can browse offline. Browser requires an active connection to show anything.

Biometric Login

App uses your fingerprint or face to log in instantly. Browser requires you to type your password every session.

Battery Life

App is optimised for mobile hardware and uses 40% less battery than a browser tab left open during play.

Payment Shortcuts

App remembers your DANA, OVO, GoPay or QRIS choice and deposits in one tap. Browser makes you select your method each time.
