Why download the 399bot app?
Website vs. app — what's the difference?
Many people wonder why they need a separate app when the browser works fine. The truth is, the dedicated 399bot app offers a noticeably different experience. Once you try it, you will see the difference right away.
First, the app loads much faster. A browser has to reload everything from scratch each time, but the app keeps core files cached, so games start up with minimal delay.
Second, push notifications. When 399bot launches a new promotion or special bonus offer, the app sends an instant notification to your phone. You won't get this with a browser.
Third, security. The app supports fingerprint and Face ID login, so you never have to type your password repeatedly — and no one else can easily access your account.
App performance
The 399bot app is lightweight and built to use minimal RAM. It runs smoothly even on older Android phones, with less heat buildup and better battery efficiency during gameplay.
If your internet connection drops, the app automatically reconnects. If the connection cuts out mid-game, it can restore your previous session.
Safe installation
When installing the APK on Android, you will need to allow "Install from unknown sources." This is a standard Android warning shown for any app installed outside the Google Play Store. The 399bot APK is completely safe and virus-free. You can turn off that permission again after installation if you prefer.
Full installation instructions for iOS users are available on the installation page. Once installed, the app runs very smoothly on iPhone.
Android installation tips
Once the APK is downloaded, locate it in your file manager. Tap "Install" and the installation will complete in under a minute.
IOS installation tips
Go to Settings → General → VPN & Device Management and trust the 399bot app. After that, you can use it normally.
Play on a weak connection
The app works on 2G/3G networks too. It uses less data than the web version, so you save on mobile data.
Keep notifications on
Keep notifications enabled in the app settings to receive bonus offers and promotion alerts.
