WhatsApp is a globally popular messaging platform owned by Meta that enables users to send text and voice messages, make voice and video calls, and share various media types, including photos, documents, and locations. The application is distributed through two primary mobile app marketplaces: Google Play Store, which serves Android devices manufactured by various companies, and Apple App Store, which exclusively serves Apple’s iOS devices such as iPhones and iPads. These platforms differ significantly in their market demographics, user base, revenue models, and regional penetration, which directly impacts WhatsApp’s download patterns across different countries.
