What makes the 12b app different?
Smartphones are no longer just for communication — they're a whole world of entertainment in your pocket. With millions of people across Bangladesh going online via mobile every day, 12b built their app with exactly those users in mind.
The difference between betting on a website and betting on a mobile app is something you have to feel for yourself. The first thing you notice when you open the 12b app is speed. Pages load instantly, buttons respond the moment you tap them. Whether you're sitting on the beach in Cox's Bazar or riding a rickshaw through Dhaka – wherever there's internet, the 12b app works.
Another great feature is push notifications. Whether a big match is about to start, a new bonus offer drops, or your bet result is in — the app lets you know automatically. No need to open the site and check manually.

Steps to install the 12b app on Android
Most people in Bangladesh use Android phones. Even though 12b isn't available directly on the Google Play Store, installing the APK file is straightforward. Read through the steps below once and you'll have the whole thing done in just 2–3 minutes.
Enable Permission in Settings
Go to your phone's Settings > Security or Privacy. Enable "Unknown sources" or "Install unknown apps". You only need to do this once.

Download the latest APK file from the official 12b website. The download typically completes in 30–60 seconds.
Open the file
Find the downloaded APK file in your notification bar or file manager. Tap it to begin installation.
Tap the Install button
An "Install" button will appear on screen. Tap it and installation completes within 15–20 seconds.

How to get the 12b app on iOS
IPhone and iPad users get the full 12b experience too. Installing the app on iOS works a little differently than on Android, but it's just as straightforward.
The iOS version of 12b can be added to your home screen as a PWA (Progressive Web App) via Safari. It's essentially a shortcut, but it behaves just like a native app – with push notifications, offline caching, and full-screen mode all included.
Open the 12b site in Safari, tap the Share icon at the bottom, and select "Add to Home Screen". That's it – the 12b icon will appear on your home screen and work just like any other app.
App vs. Website – Which Is Better?
A lot of people wonder – why bother with a separate app when you can just use 12b on a mobile browser? The answer is simple: the quality of the experience.
