More About the 3999bit App

Smartphones are everywhere in Bangladesh today — at home, at work, on the go. Mobile is the primary device for most people. 3999bit understands this reality, which is why the mobile app is their top priority. It offers more features than the website and delivers a far smoother experience.

App vs. Mobile Browser

Many users ask — why bother installing the app when the mobile browser works just fine? And that's fair — you can use 3999bit through a browser. But the app gives you push notifications, biometric login, faster loading, and lower data consumption. For regular bettors, those advantages make a real difference.

How much data does it use?

The 3999bit app is easy on your data. Regular browsing and placing bets uses just 3–5 MB per hour. With live animations on, that goes up to 8–12 MB. In low-data mode, animations are turned off and everything runs on as little as 2 MB.

Which phones are compatible?

Android 5.0 (any Android phone from 2014 onwards) and iOS 13.0 (iPhone 6s and later) are supported. The 3999bit app runs on older smartphones too — it's been optimized specifically for budget phones with limited RAM.

How do I update the app?

When a new Android update is available, a notice will be posted on the 3999bit download page. Simply download the new APK and install it over the existing app — your data will not be lost. On iOS, the PWA updates automatically with no action needed.

The 3999bit app is 100% safe. Every download is virus-scanned before release. SSL encryption and OTP verification keep your account and funds fully protected.
