The 305ok Android app is available as an APK file. Even though it's not on the Google Play Store, installation is straightforward — just follow the steps below.
Download the latest 305ok APK file from the download page. The file is small, so it won't take long.
Go to your phone's Settings → Security or Privacy and enable "Install unknown apps" or "Unknown sources."
Tap the 305ok APK file in your Downloads folder, then press the "Install" button.
Once installed, open the app and log in to your account or register a new one.
Don't panic if you see a "Harmful app" warning during installation. This is Android's standard alert for third-party APKs. Just tap "Install anyway" to proceed.
IPhone users can get the 305ok app just as easily. There are two ways to install it on iOS.
The first method is to open the 305ok website in Safari and select "Add to Home Screen." This creates an app-like icon on your home screen that runs in full-screen mode as a web app. It's the easiest option and requires no download.
The second method lets you install the native app via TestFlight or an enterprise certificate. Visit the 305ok download page or contact support for full details on this method.
Open 305ok.bet in Safari on your iPhone. This method will not work in Chrome or Firefox.
Tap the Share icon (box with an arrow) at the bottom center of the screen.
Select "Add to Home Screen", give it a name, and tap "Add". The 305ok icon will appear on your home screen.
Which one works better for you?
Mobile internet usage in Bangladesh is growing every day, with most people now turning to their smartphones for entertainment. The 305ok app was built with exactly this reality in mind.
Given Bangladesh's network conditions, the app performs well even on 3G. Users in rural areas where 4G isn't always available can use the 305ok app without any issues.
Demand for the app peaks during cricket matches. With thousands of users placing live bets simultaneously during IPL, BPL, or national team games, 305ok's servers handle the load without slowing down.
Easy payments are a big deal for many users. You used to need a separate app to deposit money — now you can pay via Mobile Pay, Nagad, or Rocket right inside the 305ok app. Everything in one place.
For Live Casino games, video quality in the app is better than in a web browser. You can also chat with the dealer. Slot games run with smoother animations in the app as well.
The 305ok app runs on Android 5.0 and above, and iOS 12 and above. It should work fine on older phones, though you'll get the best performance on an updated OS.

User Experiences from Across Bangladesh
Paying via Mobile Pay has become so easy since I switched to the app. I used to do it through the browser — now there's no need. Live cricket betting feels so much smoother on the app too.
The slots look stunning on the app. The fingerprint login is genuinely convenient, and playing in dark mode at night is so much easier on the eyes.
It runs well even on my older phone. Low data usage is a big plus for me. I've caught plenty of bonus offers on time thanks to the notifications.
Since installing the 305ok app, I never bother with the browser anymore. The Live Casino video quality is so much better, and withdrawals are a breeze now.
I use it by adding it to my Home Screen in Safari — feels just like a native app. Everything is available in Bangla, which makes it really convenient.
The network can be patchy out here in the village, but the 305ok app holds up most of the time. During cricket season, it's absolutely essential.
