Our app puts the full ultra138 lobby on your phone — slot rooms, live dealer tables and the sportsbook betslip, all one tap from your home screen. Install...
The ultra138 app is built for one-handed use on the go. Open slot rooms from Pragmatic and PG Soft in a vertical lobby, swipe to live baccarat or roulette, and keep your sportsbook betslip pinned at the bottom. Fingerprint or Face ID signs you in instantly. Quick-deposit shortcuts pull DANA, OVO, GoPay and QRIS into a single confirm tap, and push alerts
ping you when your match kicks off.
Getting the app on your phone takes under two minutes. Android users grab the signed APK directly from us — we don't list on third-party stores. iOS users follow the TestFlight or profile link. Once installed, sign in with your existing ultra138 account or open a new one inside the app.

A short illustrated install page walks through Android unknown-sources prompts and iOS profile trust. Bookmark it on your phone browser in case you ever reinstall after switching devices.
Every Android build is signed with our developer certificate. Your phone verifies the signature on install, and updates only accept the same key — protecting you from tampered copies floating around messaging apps.
We distribute only from ultra138.bet. If you see our app on a random APK mirror, it's not from us. Always grab it from the download button on this page.
Lost your phone? Sign in on another device, revoke the old session from security settings, and re-enable biometrics on the new install. Your balance, history and favourites are tied to your account, not the device.
All traffic between the app and our servers runs over TLS 1.3. Deposits via DANA, OVO, GoPay and QRIS use tokenised handoffs, so card-style details never sit in the app.
The app asks only for what it needs — storage for the install, notifications for alerts, biometric for login. We don't request contacts, SMS or location beyond region check.
We push security and lobby updates every few weeks. The app prompts you when an update is ready and installs over the existing version without touching your saved login.
| Login speed | App unlocks with fingerprint or Face ID in under a second. The mobile browser asks for your password each session unless you trust the device, which adds friction every visit. |
|---|---|
| Notifications | Only the app delivers push alerts for kick-offs, live table seats and promo drops. The browser can't ping you when it's closed, so you'll miss time-sensitive markets. |
| Live streams | Live dealer video runs smoother in the app thanks to native players. Browser streams work but use more battery and can stutter on patchy 4G across busier Indonesia areas. |
| Deposit flow | The app remembers your DANA, OVO, GoPay or QRIS choice and confirms in two taps. The browser flow re-asks each time and reloads the wallet page between steps. |
| Offline behaviour | App caches your lobby so you can browse without signal. The mobile browser shows a blank error page the moment your connection drops, losing your scroll position too. |
| Storage cost | App takes around 30MB plus cache. The browser uses zero install space but burns more mobile data on every visit because nothing is cached between sessions. |
