The time it takes to create an app can vary greatly depending on the complexity of the app, the experience of the developer, and the clarity of the project requirements. A simple app with basic functionality might take a few weeks to a couple of months, translating to roughly 80-300 hours of development time. However, a more complex app with multiple features and custom elements can take several months to over a year, meaning 500-2000+ hours of work. It's also important to factor in additional time for planning, design, testing, and post-launch updates.
