Codecademy Go

Codecademy has been around for years, but it has grown into a much more complete platform for coding and tech skills. You can choose from career paths and skill paths in topics like Python, JavaScript, web development, SQL, AI, cloud computing, and cybersecurity.

Lessons happen inside an interactive code editor inside the app, so you write and run code as you learn rather than watching someone else type. As you progress, you build small but real projects that can become part of your portfolio. While the mobile editor is surprisingly capable for quick practice, you can seamlessly switch to the desktop version for more intensive coding sessions if things feel a bit cramped on your iPhone screen.

If your long-term goal is a job in software engineering, data science, or analytics, Codecademy’s structured paths and certification prep are a solid option.
