Mobile applications, also called mobile apps, allow users to access internet services on their portable devices like smartphones. They make it easier than using desktop computers. Mobile apps can be utilities, enterprise tools, or games. They are designed for handheld use so people prefer them over laptops for browsing websites or playing games on the go. For example, a traveler can book a bus ticket using a mobile app instead of a desktop. Mobile apps offer advantages like faster downloads optimized for mobile, engagement through location and contact features, and branding through a constant connectivity presence. They work across smartphone platforms like Android, iOS, Blackberry and more.
