Ko66 delivers the same full experience on both Android and iOS. Download the version that fits your device.

Runs smoothly on iPhone and iPad. Supports iOS 13 and above. Install directly from the App Store.
Why Use the App?
Most people in Bangladesh now access the internet on their phones. ko66 built its mobile app with exactly that in mind. Browsing the website on a browser can't match the app experience — pages load faster, notifications arrive instantly, and placing a bet takes just two or three taps.
At just 50 MB, the app takes up very little space even on older phones. It's optimised for Bangladesh's 3G and 4G networks, so it works well even on weak signals. We've heard great feedback about this from users in rural areas too.
Log in to ko66 once and you're set — the app takes you straight to your account every time you open it. You can also log in quickly using fingerprint or Face ID, so there's no time wasted getting to your favourite match.
Every second counts during live betting. Live odds updates on the ko66 app are even faster than the web version. With push notifications enabled, you'll know before a match kicks off — so you never miss a bet.
