When it comes to continuous delivery for mobile apps, several key differences must be considered due to the unique characteristics of mobile devices and environments. Mobile apps run on a wide range of hardware and software environments, with only two operating systems to worry about, and display resolutions vary widely, making testing more complex. Automated deployment is also crucial as installation and updates are typically handled automatically by users or admins. Additionally, multiple code branches may be necessary due to the variety of app types, such as native, web-based, or hybrid apps. An agile development framework and automated deployment process are also essential for mobile continuous delivery pipelines.
