GB WhatsApp is a modified version of the official WhatsApp app that offers extra customization options, privacy features, and advanced controls that aren’t available in the original version. With GB WhatsApp, users can change themes, hide online status, send larger files, and enjoy more flexibility in messaging. It’s popular among people who want a more personalized and feature-rich chatting experience, but it’s not an official app, so users should download and use it carefully.
