FM WhatsApp is a modified version of the standard WhatsApp application that offers users additional features and customization options. These features include enhanced privacy settings, such as the ability to hide online status and blue ticks, as well as customization options for themes, fonts, and chat backgrounds. FM WhatsApp also allows users to send larger files, such as videos and audio files, and increases the limit for sending images in a single message. Additionally, FM WhatsApp enables users to use multiple WhatsApp accounts on the same device, providing greater flexibility for those who manage multiple phone numbers or accounts.
