What Programming Languages Should I Learn to Build a Personal App?

To create a Windows app, I'd recommend learning C#. For Android, go with Kotlin, as it's officially supported. If you’re looking for something cross-platform, you could try .NET MAUI with C#. Alternatively, if you’re open to web apps, a Progressive Web App (PWA) can work across all devices, which could be worth considering!

Learning Kotlin is a solid choice, especially for Android development. It's modern and easy to get into.

If you're starting with a personal app, Python is a great language to start with for Windows. For Android, go for either Java or Kotlin. If cross-platform is your goal, Java or Kotlin will also serve you well there! But if you need internet connectivity and server storage, then jumping into web development with JavaScript could be a smart move.

For Windows, consider using C++ with React Native. For Android, you might look into C++ with a JNI bridge, which can be a bit complex but powerful!

Focus on either Java, JavaScript, or Python to start your programming journey. Don’t stress about the specific language, as they are just tools to help you learn coding fundamentals. Given your interest in versatility, JavaScript is worth looking into since it’s super flexible and can handle various applications pretty easily.
