About the 399 bit Mobile App
The 399 bit app is available on both Android and iOS and can be downloaded through official channels. It is the full version of the site — everything available in the browser is available in the app too, just arranged more smoothly for a phone screen.
For detailed installation instructions and information about the APK file, visit the 399 bit APK page.
You can log in from any device — phone, tablet or computer — using a single account. Your balance, betting history and bonuses all stay in sync. A deposit made on one device shows up instantly on another.

VIP points and cashback accumulate equally when using the app. From Bronze to Platinum — the benefits of every tier can be viewed in the app.
App vs Browser — What Is the Difference?
Many players ask: what is the real difference between playing in a phone browser and playing in the app? The answer is simple: one account, one balance. If you have ৳5,000 in the browser, the same amount shows when you open the app. Betting history, bonuses and VIP level are all the same everywhere.
However, the app has a few extra advantages. Even on a small screen, buttons and menus are sized for fingers. During live matches, odds update instantly without reloading the page. And there is no need to search for a browser bookmark — the app icon sits directly on your home screen.
Nothing needs to be installed to play in the browser, but you may need to log in each time. In the app, one login keeps the session active longer, so you do not have to enter your password repeatedly.
Keep Your Phone Login and Security in Check
When using your 399 bit account on mobile, keeping a few things in mind will keep your account safe. Use a strong password and never share it with anyone — the support team will never ask for your password. When an OTP arrives at login, verify it and do not share it with anyone else.
Detailed information about the login process is available on the 399 bit Login page.
- Keep a screen lock (PIN, fingerprint or face unlock) active on your phone so no one else can open the app.
- OTPs only arrive during login or transactions — never give an OTP to an unknown person who asks for it.
- Do not share your password with anyone, not even friends or family.
- Avoid making transactions over public Wi-Fi. Use mobile data or a trusted network.
- If you use a shared device, log out after each session.
Some Tips for Running the App Smoothly
A stable internet connection is important for live betting or live casino. On a weak connection, odds may load slowly, which can cause problems with live bets. Using Wi-Fi alongside mobile data keeps the experience more stable.
When a new version of the app is released, update it through official channels. Some newer features may not work on older versions, and security updates may be missed.
If your phone is low on storage, the app may run slowly. Clearing unnecessary files from time to time keeps app performance up. For any technical issue, the 24/7 live chat support team is ready to help.

Fishing Games and More in the App
The 399 bit app is not just slots or sports — there is also a large collection of fishing games. Popular fishing games from JILI, JDB and Spadegaming feel great on a phone touchscreen. Aim carefully, catch fish and rack up points.
