Download and install mantra303
Four steps to get started
- Download the mantra303 APK (Android) or visit mantra303.app (iOS / desktop) and save the app to your home screen if you prefer an app-like experience.
- Open the app or browser and choose Create account, then fill in your email, username, password, and mobile number.
- Upload your national ID or passport and a proof of address (utility bill or bank statement) for account verification, which normally completes within subject to verification.
- Add your deposit method (DANA, e-wallet, mobile banking, local payment, online payment, e-wallet, or direct bank transfer to mobile banking, local payment, online payment, or e-wallet) and fund your account to begin.
App versus browser — what works best for you
The Android APK gives you offline account caching so you can review your betting history and account balance even without an internet connection, and push notifications arrive faster than browser alerts. The app uses less battery than keeping a browser tab open for hours. However, the iOS browser and web versions are equally quick because we serve them through the same content network and backend as the app, and you avoid waiting for app updates when we make small improvements. If you use multiple devices — phone for browsing, tablet for live-dealer tables, laptop for detailed match previews — the browser approach keeps you in sync without downloading to each one. Most players find the app fastest for the first 30 seconds of login and then browser-only after that, so pick whichever feels natural to you.
Device requirements and compatibility
We support Android 7 and above (released in 2016) and iOS 12 and above (released in 2018), which covers the vast majority of phones in use today. If you have an older device, try the browser version on mantra303.app first — browsers often work on devices slightly older than our app minimum. For very low-end phones or tablets with limited storage, the browser approach uses less space and RAM than the APK, though you do need an active internet connection each time you open it.
Common installation issues and solutions
If Android shows "Unknown sources" or "Install unknown apps" during download, go to your phone's Settings, find the app or browser that downloaded the file (usually Chrome or your file manager), and enable "Allow installation of apps from this source." After you tap Install, the system may ask you to trust the certificate — confirm it and the installation continues normally. If iOS says the app cannot be opened because the developer is not trusted, open Settings, go to General > VPN & Device Management, find the mantra303 profile, and tap Trust. These are standard security checks on older iOS versions and do not indicate a problem with our app; once you trust it, you can use it without restrictions.
Data, permissions, and account security
We request permission to access your device's camera (for ID photo uploads during verification) and contacts (to autofill your email on login). We do not sell or share your data; all account information is encrypted end-to-end between your phone and our servers. Your deposit history and withdrawal requests are kept private and visible only to you and our support team. We use industry-standard certificate pinning so your app connection cannot be intercepted, and we log out your session after subject to verification of inactivity for additional safety. If you lose your phone, you can recover your account by logging in on another device using your email and password — your funds remain secure because we authenticate withdrawals through a separate email confirmation link that we send to the address on file.
