The b444 App — Why Mobile Is the Best Way to Play
A large share of internet users in Bangladesh go online through their mobile phones. Recognising this, b444 has made its mobile app the most prioritised part of the entire platform. You get more from the app than from the desktop — because mobile unlocks certain advantages that simply aren't possible on a desktop.
Why push notifications matter for live matches
Timing is everything in cricket betting. When a big wicket falls or the run rate suddenly shifts, odds can change in seconds. If the b444 app isn't open at that moment, you could miss the best price. With push notifications enabled, your phone alerts you even when you're not in the app — so you never miss the right moment. You can fully customize your notifications in the b444 app: cricket only, football only, Live Casino bonuses — whatever matters to you.
Direct Deposit via bKash & Nagad
You can deposit via bKash, Nagad, and Rocket directly within the b444 app — no need to open a separate browser or leave the app. Simply enter the amount on the payment screen, select your payment method, and enter your mobile banking PIN. The entire process takes under 30 seconds. When you need a quick deposit in the middle of a live match, nothing beats this.
No concerns about app security
The b444 Android APK is downloaded directly from the official server. The file carries a SHA-256 digital signature, which Android verifies automatically during installation. We strongly advise against using APKs downloaded from third-party sources. Downloading only from the link on this page is the safest option.
After logging in, we strongly recommend enabling two-factor authentication (2FA) to keep your account secure. You can turn it on easily from Settings in the b444 app. With biometric login active, even if someone knows your password, they won't be able to log in without your fingerprint.
What about older or budget phones
The b444 app is specially optimized to run smoothly even on lower-end phones. It works on any device running Android 6.0 or above — including phones with as little as 1 GB of RAM. Live betting is perfectly manageable even on a budget 4G phone. For Live Casino video streaming, though, a stable 4G or Wi-Fi connection will give you the best experience.
If your phone is low on storage, use the mobile web instead — nothing gets saved to your device, but you'll still have access to almost all features. The only thing you'll miss out on is push notifications.
A Note for iOS Users
IPhone and iPad users can download the b444 app straight from the App Store — no need to enable "Unknown Sources" like on Android. Downloading from the App Store means the app has already passed Apple's security review. Face ID login on the iOS app is incredibly fast — just pick up your phone and it unlocks instantly.
Add to home screen — PWA support
If you'd rather not download the app, open b444 in your mobile browser and tap "Add to Home Screen". This places a b444 icon on your home screen that looks and feels just like an app. Tap it and the site opens in full screen with no browser bar in sight. You save storage space and still get an app-like experience.
How to update the app
The b444 app is updated regularly — to roll out new features, strengthen security, and improve performance. On Android, the app notifies you automatically when an update is available. Simply download the new APK and reinstall — your account and data will remain intact. On iOS, you can keep auto-updates enabled through the App Store.

- Your balance and history are never lost during an update — everything is saved on the server
