About this app

Learn to code the fun way with Coddy - the gamified coding app that turns programming into a daily habit. Think of it as Duolingo for coding. Whether you're picking up Python, getting into JavaScript, building web pages with HTML and CSS, learning SQL, or diving into AI prompt engineering - Coddy helps you practice through short, hands-on lessons that actually stick.

Learn by Doing

Forget boring theory. Coddy gives you bite-sized challenges where you write actual code, run it, and see results right away. You'll work through puzzles, build small projects, and start understanding how loops, functions, variables, and conditionals really work - not by reading about them, but by using them.

Coddy's built-in code editor lets you code directly on your phone, building real intuition instead of just memorizing syntax. Whether you're learning Python, practicing JavaScript, or writing your first HTML - every lesson gets you coding from the start.

Build Real Programming Skills

Python basics? Web development with HTML, CSS, and JavaScript? SQL queries? Java or C++ for your CS course? This coding app checks your code automatically and explains what went wrong, so every mistake becomes a learning moment.

And it's not just traditional coding. Coddy also teaches AI prompt engineering - how to write effective prompts for ChatGPT, Claude, and Gemini. Learn it right here alongside Python, JavaScript, and everything else.

18+ Languages and Technologies

One app, no limits. Learn Python, JavaScript, TypeScript, HTML, CSS, SQL, Java, C++, C, C#, PHP, Swift, Rust, Lua, Ruby, R, Bash and terminal commands, and AI prompt engineering. Build websites, make apps, crunch data, get into game development, or master the command line - there's a path for you.

And yes, we have Rust and Lua. Good luck finding another coding app that teaches those.

Daily Progress That Keeps You Going

Coddy makes consistency easy with streaks, XP, badges, and leaderboards that make every day feel like progress. Keep your streak alive, earn rewards, climb the ranks. It sounds like a coding game because it kind of is - except you're building real programming skills while you play. Whether you're working through a Python course, learning JavaScript step by step, or practicing HTML and CSS - every session counts.

Personalized Practice That Adapts to You

Coddy doesn't give everyone the same coding lessons. The app tracks what you know and where you struggle, then builds custom challenges and quizzes around that. Learning Python? Your practice adapts as you improve. Picking up JavaScript or HTML? Same thing. Over 1M coding challenges, quizzes, and exercises across every programming language - tailored to your level so you're never bored and never lost.

Daily Challenges

Test yourself every day with fresh coding challenges designed to push your skills. Solve problems in Python, JavaScript, SQL and more - earn XP to climb the leaderboard.

Fresh Content Every Week

New coding challenges, lessons, and projects added regularly. Go deeper in Python, pick up JavaScript, try HTML and CSS, or start a completely different programming language.

Made for Beginners (Seriously)

Zero programming experience required. Coddy was built for the curious - students learning Python for the first time, career switchers picking up JavaScript or HTML, or anyone who wants a fun daily coding challenge that's actually useful. This learn to code app adapts to your pace, so you never feel lost.

Ratings and reviews

It's a fun app. I've been doing the Python lessons; they start simple enough for beginners and progress to the point where I feel like I'm learning something every lesson. It's possible to do quite a few lessons per day even for free. My only complaint is that several times, the code given as the solution for a challenge uses a concept that hasn't been covered yet. Edit: Yes, I'll give five stars if this is fixed. If you can't find issues, email me for details - no room here.

Great app! UI is great and easy to use. I love that I can use the same app to learn all different types of coding. The only issue that I have with it is that I paid for the "lifetime coder" thing and I still have to watch ads sometimes. That's kind of ridiculous. It's a great app, don't get me wrong, just the advertising of the subscriptions was a little skewed in my opinion.

the app is great and its phenomenonal!! just the only thing bad is the energy system, add more energy or at least more unlimited ads to watch for energy then you guys will make more money and I will also get to learn programming a lot faster. thanks you coddy team for noticing . I understand the update should be suitable for everybody. I also have another problem, when I compile and it shows and error, sometimes I am not able to understand the error, if you can, please add a mini summary for it.
