App Capabilities Worth Knowing
These are the four functions that make the umi555 app different from opening a browser tab on your phone.
Biometric Login
Fingerprint and face unlock work on supported Android and iOS builds. Skip the password every time you return — your account opens in under two seconds on most mid-range devices.
Push Notifications
Opt in to alerts for promo board updates, live table openings, and account activity. Notifications arrive even when the app is running in the background, so you never miss a short window.
Dark Mode
The app ships with a dark interface by default — easier on the eyes during late-night Mahjong Ways or Dragon Tiger sessions, and lighter on battery on OLED screens.
Lobby Preview Offline
Browse game thumbnails and table schedules even on a weak connection. The lobby cache loads the last known state so you can plan your session before the signal improves.
DEVICE REQUIREMENTS
Supported Devices and System Versions
The umi555 app is built for the phones most Indonesia players actually use — mid-range Android handsets and current iOS devices. Check the table below before you install.
iOS Version
iOS 13 and above. The home-screen shortcut method works on Safari; third-party browsers on iOS do not support the install prompt.
RAM
Minimum 2 GB RAM. For live casino streams from Evolution or PG Soft tables, 3 GB or more keeps the video feed stable without frame drops.
Storage
The APK is approximately 30 MB. Allow an additional 50 MB for cached lobby data and game assets that load on first use.
Supported Regions
Availability depends on local law and is accessible where local regulations permit. Check your region's eligibility before completing account registration.
What the umi555 App Adds to Your Session
Open the app and your last session picks up where you left off — live Baccarat table, Aviator Quick Arena crash round, or a Pragmatic Play slot mid-spin. Push notifications let you know when a new promo is live on the board, so you're not refreshing a tab. Quick deposit from your e-wallet takes three taps: open DANA, OVO, or GoPay, send
to the account number shown, confirm with your PIN. Fingerprint login skips the password screen entirely on supported Android and iOS devices. The betslip stays pinned while you browse other markets, so switching between a football match and a slot room doesn't lose your selections.
Install in 3 Steps
Android users download the APK directly from umi555 — no app store needed. iOS users access the app via the Safari browser shortcut, which installs a home-screen icon that behaves like a native app. The whole process takes under two minutes on a standard mobile connection. Once installed, sign in with your existing account credentials or complete a new account registration inside
the app. Your wallet balance, transaction history, and game preferences carry over automatically — nothing resets between the browser version and the app.
- Download the APK or add to home screen — On Android, visit umi555 on your mobile browser and tap the download link for the APK file. On iOS, open the site in Safari and use the Share menu to add it to your home screen.
- Allow install from unknown sources (Android only) — Go to Settings → Security → Install unknown apps, then allow your browser to install the file. This is a one-time step; you can turn it off again after the install completes.
- Open the app and sign in — Tap the umi555 icon on your home screen, enter your account details, and enable fingerprint login when prompted. Your full lobby — slots, live tables, sportsbook — is ready immediately.
Common Questions About the umi555 App

Your balance, transaction history, and game preferences are tied to your account, not the device. Everything syncs automatically when you sign in on the app.
