GB WhatsApp is a modified version of the WhatsApp. It is designed to offer users additional features. GB WhatsApp introduces various customization options, extra privacy controls, and larger file-sharing capabilities. 

One of the main advantages of GB WhatsApp is its enhanced customization features. Users can change the appearance of the app by adjusting themes, modifying chat bubbles, and even altering the font style. This allows for a more personalized experience, which appeals to many users who enjoy customizing their apps.

Privacy is another area where GB WhatsApp offers more features. It gives users the ability to hide their "last seen" status, disable read receipts (the blue ticks), and even hide the typing indicator. However, there are several downsides to using GB WhatsApp that need to be considered. The app may not be as secure as the official version. Because it’s not an official app, there is also no official support for troubleshooting issues.

Another major downside is the risk of having your account banned. WhatsApp has made it clear that using modified versions of their app, like GB WhatsApp, can result in temporary or permanent bans. For this reason, users should carefully weigh the risks before deciding to download GB WhatsApp.

In conclusion, GB WhatsApp offers additional features that may appeal to users who are looking for more customization and privacy controls. It allows for a more personalized experience, supports larger file sharing, and offers more control over privacy settings. If you are someone who values security and reliability, it might be safer to stick with the official WhatsApp app. However, for those willing to accept the risks for extra features, GB WhatsApp might still be worth considering, but only with caution.
