Overall web development is relatively simpler than Android development, but it mostly depends on the project you’re building. For example, developing a web page using HTML and CSS can be considered simpler than building a simple Android application.
App stores are constantly improving search capabilities to make it easier to find new apps, but app stores aren’t as accessible as the web. Websites still offer small businesses a better chance of being seen than a mobile app. Creating a website is often cheaper and takes less time than building an app.
