What are the key differences between FM WhatsApp and YoWhatsApp?

• FM WhatsApp offers extensive customization options such as theme changes, privacy controls, and various chat and media settings. YoWhatsApp (Aero WhatsApp) also provides extensive customization but is known for its lightweight performance and additional features like advanced privacy settings and built-in chat lock options. Both apps enhance the standard WhatsApp experience but cater to slightly different user preferences.
