At home or on the go, the a111 app is always with you. Available on both Android and iOS, with all menus in Bengali and the full platform fitting in just a few megabytes — right in the palm of your hand.
Built from the ground up for mobile — not a browser port
Many betting platforms simply shrink their website down and call it an "app." a111 didn't take that shortcut. The a111 app was built from the ground up specifically for mobile users. Every button, every menu, every screen has been designed with Bangladesh's network conditions, screen sizes, and the way people actually use their smartphones in mind.
The navigation is built with one-thumb use in mind — so you can place a bet while stuck in Dhaka traffic. A low-data mode keeps games loading even on weak connections around Chittagong's port area. Dark theme is set by default for comfortable late-night play. It's these small, thoughtful decisions that make the a111 app stand out.
Sports Betting, Live Casino, slots, poker, and lottery — all available in one app through a111. No need to download separate apps. One account, one wallet, full access to every section.
Another major perk is push notifications. When you're playing on a website, it's easy to miss bonus offers or match updates. With the a111 app installed, you'll get notifications sent directly to your phone before a match kicks off, when a bonus is credited, or when a withdrawal is completed — even without opening the app.
Biometric login is another feature many users love. Instead of typing a password every time, you can open the a111 app with just a fingerprint. iPhone users can also log in with Face ID. This feature doesn't just save time — it adds an extra layer of account security.
Every feature built with Bangladesh mobile users in mind
Menus, buttons, notifications, and customer support — everything is in Bengali. No English knowledge needed.
Even on a 3G connection, the home screen is ready in just 1 second after the app opens. No delays, no lag.
Log in instantly with your fingerprint or Face ID — no more worrying about forgotten passwords.
Bonus alerts, match kick-off reminders, and payment updates are sent straight to your phone — you won't miss a thing, even with the app closed.
On slow connections, image compression kicks in automatically, cutting data usage by 40%. Works even in areas with weak signal.
Dark theme is set by default to keep your eyes comfortable. Even during long late-night sessions, eye strain won't be an issue.
Get support in Bengali via live chat without ever leaving the app — help is always right at your fingertips.
Watch live scores on the same screen while you place your bets — no need to switch away from the match.

The a111 app keeps getting better with regular new features and improvements
Below is a list of popular Bangladeshi devices
Among the best-selling phones in Bangladesh, the Samsung Galaxy A series, Infinix, Tecno, and Xiaomi Redmi series are hugely popular — and the a111 app runs smoothly on all of them. It works on phones with as little as 2 GB RAM, though 3 GB or more gives you a noticeably smoother Live Casino video streaming experience.
Entry-level phones like the Infinix HOT 20i, Tecno Spark 20, Samsung Galaxy A14, or Redmi 12 can all run Sports Betting and slots on the a111 app without any issues. Live Casino may require a slightly better phone or a more stable internet connection. iPhone users get the best performance on any model from the iPhone 8 onwards.
On the network side, the app works on all major operators — Grameenphone, Robi, Banglalink, and Teletalk. Sports Betting runs perfectly fine on 3G. For Live Casino video, 4G gives you an even better experience. WiFi delivers the best performance overall.
A111 app updates roll out every few weeks. Android users can download the latest APK from a111.world and install it over the existing app — your data won't be affected. iOS users can enable automatic updates from the App Store. If you haven't updated, the app will send you a notification.
What a111 app users from across Bangladesh are saying
"I installed the a111 app on my Tecno Spark 20. I wasn't sure it would run well on a lower-RAM phone, but it works perfectly. No lag at all on Sports Betting. And thanks to push notifications, I never miss IPL bonus offers anymore."
"I run the a111 app on my iPhone 13. Face ID login is fantastic — one glance and you're in. I was a little surprised to see a Bengali menu, since apps like this usually come in English. Being able to understand everything in your own language is genuinely reassuring."
"I used to play on the browser, but once I installed the app, the difference was clear. The browser would randomly log me out; the app never does. The live casino video is also much smoother on the app than in the browser. I'd recommend everyone to install the a111 app."
