<human>:  What are some important differences between web development and app development?
<bot>: Some important differences between web development and app development include the development language used, the platforms used to run the app, the device compatibility and the monetization approaches. Web development typically uses languages such as HTML, CSS and JavaScript, while app development often uses languages such as Swift and Java. Web development is mostly designed to be used on web browsers, while app development can take advantage of the features of mobile devices and run natively on mobile operating systems. Furthermore, app development needs to take into account device compatibility, ensuring that it works properly on different kinds of devices and operating systems. Finally, web and app development involve different monetization approaches. For example, web developers often monetize through advertising, while app developers can monetize through in-app purchases and subscription models.
