Installation paths for koi on mobile
We offer three ways to access koi on mobile devices. Android users can download our APK directly from our website and install it on their device. iOS users access koi through Safari or Chrome browser without needing an app store download. Web-app users on any device can bookmark our mobile site for quick access. Each path provides the same game sections and account functionality.
Choose your access method
Android APK offers offline caching and push notifications. iOS browser and web app provide instant access without installation. All three paths connect to the same koi account and balance.
Android APK installation
To install koi on Android, download the APK file from our website. Open your device settings, navigate to Security, and enable "Unknown sources" to allow installation from sources outside the Play Store. Once enabled, open the downloaded APK file and follow the on-screen prompts. Installation takes less than a minute. After installation, open koi, create an account or sign in, and verify your email address. KYC document submission happens in-app during account setup.
iOS browser access
iOS users access koi through Safari or Chrome by visiting our website directly. No app store download is required. Your browser will prompt you to add koi to your home screen for quick access. This creates a web-app shortcut that behaves like a native app. Account setup and login work the same as on Android. Push notifications are not available through browser access, but all game sections and payment methods function identically.
Web-app access
Any device with a web browser can access koi without downloading anything. Simply visit our website and log in. The mobile-optimized layout adapts to your screen size. Bookmark the page for quick access. Web-app users can deposit, withdraw, and play all game sections. This method works on older devices and does not require storage space for an app installation.
App versus browser: what to expect on koi
Our Android APK app offers offline caching, which means some game data loads faster on repeat visits. Push notifications alert you to tournament schedules and account updates. The app runs independently of your browser, so it continues working if you close other apps. Installation requires enabling "Unknown sources" in security settings, a one-time step. Browser and web-app access provide instant availability without installation steps. iOS users benefit from browser access because it avoids app store review delays. All three paths connect to the same koi account, so your balance and game history sync across devices. Choose based on your device type and preference for installation versus instant access.
Device compatibility and system requirements on koi
We support Android 7 and above for APK installation. iOS users need iOS 12 or later to access koi through Safari or Chrome. Web-app access works on any device with a modern browser, including older phones and tablets. Our mobile interface is optimized for screens 4 inches and larger. Smaller screens display the full interface but may require more scrolling. We recommend a stable internet connection for live-dealer games and real-time sportsbook updates.
Common installation issues and solutions on koi
If Android installation fails, verify that "Unknown sources" is enabled in your device settings. Some devices label this setting differently — look for "Install from unknown sources" or "Allow installation of apps from unknown sources." If the APK file does not open, try downloading it again or using a different browser. Certificate trust warnings are normal during first installation; these indicate the APK is unsigned, which is standard for direct downloads outside app stores. If you see a warning, tap "Install anyway" to proceed. For iOS users, if the web app does not add to your home screen, try using Safari instead of Chrome, or restart your browser and try again. If you experience slow loading, check your internet connection and close other apps to free up device memory.
Data, permissions, and account security on koi
We at koi use industry-standard encryption to protect your login credentials and payment information during transmission. Your account data is stored on secure servers with restricted access. We do not share your personal information with third parties except as required by law or to process your transactions. The Android APK requests permissions to access your device storage for offline caching and to send push notifications. iOS browser access does not require special permissions beyond standard browser functionality. All account activity — deposits, withdrawals, game history — is logged and accessible from your account dashboard. If you suspect unauthorized access, contact our support team immediately to reset your password and review your account activity.
