Some users wonder why they should download a separate app when 399k already works in a mobile browser. In practice, the difference is quite noticeable. Once the app is loaded, it opens instantly every time — no repeated page refreshes like you get in a browser.
Push notifications keep you up to date on new promotions and match updates so you never miss a thing. Checking your balance, placing bets, playing games — everything feels much smoother in the app because the interface is built specifically for mobile.
The 399k app is built with Bangladesh's network conditions in mind. It runs smoothly even on a weak 3G connection. A data-saving mode is also available — when enabled, it stops the app from using extra data in the background.
Download the 399k app and log in for the first time to claim an exclusive app welcome bonus. This bonus is available to app users only.
Installing an APK on Android for the first time might feel unfamiliar, but it's actually very straightforward. Once you've done it once, it'll be easy every time after.
Go to the 399k website and register or log in, then head to the download section.
On your phone, go to Settings → Security → Unknown Sources and enable it. On Samsung devices, this option may be under Settings → Apps → Special Access.
Tap the Download button. The file will be saved to your phone's Downloads folder.
Tap the downloaded file and press "Install". Installation takes about 30-60 seconds.
Once installation is complete, tap "Open". Log in with your 399k account credentials.
The 399k APK file is completely safe and malware-free. Only download it from the official 399k website — avoid third-party sources.

Many users have shared that they used to access 399k through a browser, but after downloading the app the experience feels significantly smoother — especially with Live Casino video streaming, which buffers far less in the app.
Another great feature is the 399k app's auto-update function. Whenever new games or features are added, the app sends you an update notification automatically — no need to keep checking the website manually.
On average, the app loads 40% faster than a browser.
