How to Install the 39ko App?

Many people think installing an Android APK is complicated — but it's actually quite simple. Just follow a few steps and the 39ko app will be up and running on your phone within 5 minutes. The steps for Android and iOS are listed separately below.

Steps to Install on Android

Go to your phone's Settings → Security → Unknown Sources or "Install unknown apps" and enable it. On Samsung devices, find this under Settings → Biometrics and security → Install unknown apps.

Download the Android APK from the official 39ko page. Once the download is complete, the file will appear in your phone's notification bar.

3
Open the APK File

Tap the downloaded file and press the "Install" button. Installation takes just 30 seconds.

4
Log In or Register

Open the app and log in with your 39ko account. New users can complete registration in just 2 minutes.

Steps to Install on iPhone

1
Open 39ko in Safari

On your iPhone, open Safari and go to the 39ko download page. The installation process is easier through Safari than Chrome or Firefox.

How to Use 39ko on Desktop?

39ko delivers the full experience on desktop too, not just mobile. Open any modern browser — Chrome, Firefox, Edge, or Safari — go to the 39ko website, and access every feature instantly. The larger screen makes it much easier to track match stats and manage multiple bet slips at once.

You can also pin 39ko as a desktop app in Chrome, so you don't need to open the browser every time — just launch it with one click from your taskbar or desktop. The "Install as App" option is available on the right side of Chrome's address bar.

How to Update the App

The 39ko app is updated regularly, with new features, bug fixes, and security improvements in every release. When a new version is available, you'll see an update notification automatically when you open the app.

Android users can update by downloading the latest APK directly from within the app or from the 39ko page. Your existing data and settings will not be affected. iOS users simply need to refresh the page to get the latest version.

What's Inside the 39ko App?

New to 39ko? The first question most people ask is — just betting, or is there more? The answer: 39ko is a complete entertainment platform. Sports Betting, Live Casino, slots, virtual sports — all under one roof.

The Sports section covers cricket, football, tennis, badminton, kabaddi, and 50+ other sports. Bangladesh cricket matches and the IPL see the highest betting activity on 39ko. The Live Casino features Bangladeshi dealers who speak Bengali — an experience you won't easily find on any other platform.

The 39ko app's payment system is built specifically for Bangladesh. You can deposit and withdraw via Mobile Banking, Nagad, and Rocket — the three most popular mobile banking options. The minimum deposit is just BDT 200, and most withdrawals are processed within 30 minutes.

The app's security is rock solid. With 256-bit SSL encryption, two-factor authentication (2FA), and biometric login, your account stays protected at all times — even if your phone is lost, no one else can log in.

Common Download Issues & How to Fix Them

Some users see an "Install blocked" message when installing the 39ko APK for the first time. This happens because "Unknown sources" is not enabled on the device. Go to Settings → Security and turn it on to resolve the issue. It's a good idea to turn this setting back off once the installation is complete.

Another common issue is a download getting stuck halfway through, which is usually caused by a weak internet connection. Try switching to Wi-Fi or 4G. Also delete any incomplete download files from your file manager before trying again.

If you see an "Untrusted Developer" message on iOS, go to Settings → General → VPN & Device Management and trust the 39ko certificate. The app will work normally after that.

The app won't install if your storage is too low. Make sure you have at least 100 MB free before installing. Clear up space by deleting old photos or unused apps.
