Smooth even on a weak signal. The f21 app works on 2G — perfect for users in rural areas.
The entire app is in Bangla — menus, buttons, instructions, everything. No English required.
The app updates itself whenever a new version is released. You'll always have access to the latest features.
Many online platforms build their apps with international markets in mind, then simply release them in Bangladesh — and even when the app is good, it doesn't address the day-to-day needs of Bangladeshi users. f21 took a different approach.
F21 was built around the real-world habits of Bangladeshi users. Rural areas often have spotty coverage, so the app runs smoothly even on low bandwidth. Storage is tight on many handsets, so the app is kept to just 48 MB. And since everyone pays via bKash or Nagad, those two options are front and center.
The f21 app loads in an average of 1.2 seconds — nearly three times faster than competing apps. Odds on the live betting screen update in real time with zero lag or buffering. Whether you're on a Xiaomi, Samsung Galaxy, or Walton, the app runs just as smoothly on any mid-range phone.
Your personal information and financial transactions are fully secure on the f21 app. 256-bit SSL encryption ensures no one can access your data. The biometric login feature adds an extra layer of protection to your account.
The app offers a few extras you won't get in a browser — push notifications, biometric login, and offline access to your game history. That said, f21 works great in the browser too. Go with whichever suits you best.
The f21 development team continuously improves the app. The upcoming version 3.3 will bring custom notification filters, a dedicated cricket home screen, and a faster payment gateway — all features requested directly by users.

"Running it on a Walton Prime R7 — totally smooth. During BPL I used to do live betting on the browser and it would lag badly. Ever since I installed the app, that problem's gone. f21 app is the best for me."
"Running it on iPhone 13 — Face ID login is brilliant. Bonus notifications come through instantly. Since installing the f21 app, I haven't opened a browser once."
"The connection in my area can be a bit weak, but the f21 app still manages — payments go through and games run, even if slightly slower. I've never come across an app like this before. Honestly."
