A mobile application lifecycle encompasses several stages, including planning, development, deployment, and maintenance. Initially, a comprehensive approach is taken to define requirements and design the app. Following this, developers code the application while integrating necessary APIs and testing for functionality. Once developed, the app is deployed on platforms like the Apple App Store or Google Play. The maintenance stage involves updates, bug-fixing, and further enhancements based on user feedback and evolving market trends. Understanding this lifecycle is key for successful mobile app development.
