Can you learn to code on your phone?

Yes. In Gurwi you write code on your phone and run it right there: the console shows what your program prints. Classes are short and each one comes with exercises and questions.

Does the code really run?

Yes. Python, JavaScript and SQL run inside the app, on the phone itself, and the result shows up in the console. If there's an error, the app marks the line and tells you what broke.

Which language should I learn first?

Python is usually the easiest place to start: it reads almost like English and a few lines already do something. If you like the web, move on to HTML, CSS and JavaScript; for working with data, SQL.

Do I need to know anything first?

No. Classes start from zero and explain each idea with examples. You don't need experience or advanced math.

What happens when I make a mistake?

The error line turns red and the console tells you what happened. A tutor explains it out loud and you can ask it questions. There are also hints that show up as comments inside your code.

Which languages does Gurwi teach?

Python, JavaScript, TypeScript, HTML, CSS and SQL. HTML and CSS exercises show the page live as you type.

How much does it cost?

Gurwi is free to download and every month you can open some classes without paying. A subscription opens all of them. It works on iPhone and Android.
