Many users ask: "I can already access 4777 btu on my mobile browser, so why bother with a separate app?" That's a fair question. The honest answer is yes, you can do everything on the browser — but the app experience is on a completely different level.
First, the app is significantly faster than a browser. Browser pages need to reload every time, whereas the app caches most data in advance — so games load in just 1–2 seconds. On a fast connection you may not notice much difference, but on a slow network the gap between the app and a browser is substantial.
Another major advantage is the app's push notifications. Say you've placed a bet on a match and stepped away from your phone — the app will alert you with real-time match updates. That's something the browser simply can't do.
Third, biometric login is a great feature. Instead of typing your password every time, just log in with a single fingerprint touch. It's secure and saves you time.
