Download the ko99 app and take everything with you — live sports betting, casino games, instant bKash and Nagad deposits, and 24/7 support. Built from the ground up for Bangladesh mobile users, the ko99 app is fast, lightweight, and works great even on slower data connections.
The ko99 app isn't just a smaller version of the website. It's a purpose-built mobile experience designed around how Bangladesh players actually use their phones.
Open the ko99 app during any match and place live bets in real time. Odds refresh every few seconds so you're always working with the latest numbers. Cricket, football, kabaddi, rugby — all covered, all live, all in your hand.
The ko99 app is optimised for Bangladesh mobile networks. Pages load in under three seconds even on 3G. No bloated graphics, no unnecessary scripts — just the content you need, delivered fast so you never miss a betting window.
Deposit and withdraw directly through the ko99 app using bKash, Nagad, or Rocket. The whole process takes under a minute. Withdrawals are processed fast — most players in Bangladesh receive funds within minutes of requesting.
Turn on push notifications in the ko99 app and never miss a bonus again. Get alerted the moment a new promotion drops, when your cashback is ready to claim, or when a big jackpot event goes live. Stay in the loop without checking manually.
The ko99 app supports fingerprint and face unlock on compatible Android and iOS devices. Skip typing your password every time — one touch or one glance and you're straight into your account. Fast, secure, and genuinely convenient.
Every game available on the ko99 website is also in the app — Beach Volleyball, Bingo Adventure, Shaolin Soccer, European Roulette, Ocean King Jackpot, and more. The touch controls are optimised for mobile so games feel natural on a small screen.
Getting the ko99 app on your phone takes less than two minutes. Follow these steps for Android or iOS.
Open your Android browser and go to ko99.xyz/app. You'll see the download button clearly at the top of the page.
Go to Settings → Security → enable "Install from Unknown Sources" so your phone accepts the APK file.
Tap the Android download button. The ko99 APK file will download to your phone in seconds — it's under 25 MB.
Open the downloaded file, tap Install, and launch the ko99 app. Login with your existing account or register for free.
Use Safari (not Chrome) on your iPhone or iPad and navigate to ko99.xyz/app for the best installation experience.
Tap the iOS download button on the ko99 app page. You'll be guided through the installation profile setup.

Find the ko99 app icon on your home screen, tap to open, and login or register. Your full account is ready immediately.
The ko99 app is designed to run smoothly on the most common Android and iOS devices used in Bangladesh. You don't need a flagship phone — even mid-range devices from 2019 onwards handle the app without any issues.

Most players in Bangladesh access the internet primarily through their smartphones. That's exactly why ko99 built a dedicated mobile app rather than just making the website mobile-friendly. The ko99 app is a completely separate product — lighter, faster, and designed around the way people actually use their phones here. Whether you're on a Grameenphone 4G connection in Dhaka or a slower network in a smaller town, the app adjusts and delivers a smooth experience without the lag you sometimes get in a mobile browser.
One of the biggest advantages of the ko99 app is how it handles live betting. When you're watching a cricket match and want to place a bet mid-over, every second counts. The app keeps your session active in the background, so when you open it the odds are already loaded and you can place your bet in two taps. No page refresh, no login screen, no waiting. That kind of speed is genuinely hard to replicate in a browser, and it's one of the main reasons regular ko99 players switch to the app and never go back to the website.
The payment experience in the ko99 app is also noticeably smoother than on desktop. Depositing via bKash or Nagad through the app takes under a minute from start to finish. The app integrates directly with your mobile banking apps, so you don't have to copy and paste account numbers or switch between browser tabs. Tap deposit, confirm the amount, authenticate in your bKash app, and the funds appear in your ko99 wallet immediately. Withdrawals work the same way — request in the app, confirm, and the money hits your mobile banking account fast.
Security is built into every layer of the ko99 app. All data is transmitted over SSL encryption, the same standard used by banks. On top of that, the app supports biometric authentication — fingerprint on most Android devices, Face ID on newer iPhones. This means your account is protected by something only you have, not just a password that could be guessed or stolen. If you ever lose your phone, you can log out of all sessions remotely through the account settings.
Push notifications are another feature that app users genuinely appreciate. When a new daily bonus drops, when your cashback is credited, or when a special event goes live, the ko99 app sends you a notification so you don't miss it. You can customise which notifications you receive in the app settings — so if you only want to hear about bonuses and not general updates, that's easy to set up. It's a small thing, but it means you're always in the loop without having to check the site manually every day.
The ko99 app is free to download and there are no extra fees for using it. Your account, balance, bonuses, and bet history are all shared between the app and the website — so if you start a session on your phone and want to continue on a computer later, everything is exactly where you left it. Download the ko99 app today, log in with your existing account, and see the difference for yourself.
"The ko99 app loads so fast on my Grameenphone connection. I use it every day for cricket betting. The bKash deposit is instant — I've never had to wait more than a minute for my balance to update."
"I was using the website before but switched to the app last month. The fingerprint login is a game changer — I'm in my account in one second. The live betting section is much smoother in the app too."
"Ocean King Jackpot on the ko99 app is brilliant. The touch controls feel natural and the graphics are sharp even on my mid-range phone. Push notifications remind me about daily bonuses which I used to miss all the time."
