App and web development are distinct disciplines, each with tools, languages, and frameworks.

Mobile app development refers to creating software applications that run on mobile devices or desktops, such as iOS and Android apps, as well as Windows and macOS apps. App developers use programming languages like Java, Swift, and Kotlin and development tools like Xcode and Android Studio to create apps that can be installed on devices and accessed through app stores or other distribution channels.

On the other hand, web development focuses on creating websites and web applications that run on web browsers such as Chrome and Firefox. Web developers use programming languages like HTML, CSS, and JavaScript, as well as frameworks like React and Angular, to build websites and web applications that can be accessed through URLs.

While there is some overlap between the two disciplines, app development and web design and development require different skill sets and expertise. The choice between the two depends on the specific needs and goals of the project at hand.
