About this app

Code IDE is the most powerful mobile code editor, compiler, and AI coding assistant for Android. Write, run, and debug code in 50+ programming languages — Python, Java, C++, HTML, JavaScript, and more. Use the built-in AI coding agent to autonomously plan, build, and fix entire projects from your phone or tablet. A free coding app for developers, students, and anyone learning to code or web development.


🤖 AUTONOMOUS AI CODING AGENT

Your AI coding agent handles complete project workflows — the most advanced code generator on Android:

• Auto-Build Projects: Describe what you want — the AI creates the full folder structure, files, and boilerplate automatically.

• PLAN Mode & AUTO Mode: Review a full technical blueprint before execution, or let the agent run end-to-end autonomously.

• AI Debugging: The agent scans your file tree, pinpoints logic errors, and applies patches automatically. Fix bugs in seconds.

• AI Memory & Personalisation: Your copilot remembers your coding style and project context for a smarter experience.

• You Stay in Control: Granular permission settings and human-in-the-loop approvals mean the AI never acts without your consent.

Ratings and reviews

Great editor. I'm considering purchasing the lifetime upgrade, but there's a bug in Python 3, where, if you write a program that takes user inputs, the code doesn't run. Instead, it loads for 10 seconds and throws an error that says process killed. It doesn't load programs with user inputs. Please fix it. Overall, great editor.

Looks good, clean and uncluttered. Once i started typing, the bottom toolbar, which includes the RUN button and various useful brackets, was covered by something that wanted me to "Arrange Keywords" and I see no way to remove it. The only way i could get it to go away was to go to Settings and come back or close the app, the latter of which deleted my code. Settings are EXTREMELY minimalistic.

I have been using the CodeToInvent app for coding on mobile, and the experience has been really smooth and convenient. The app makes it easy to practice and run code anytime without needing a laptop. The interface is simple, fast, and beginner-friendly, which helps a lot while learning and testing programs. Overall, it is a very useful app for students and anyone who wants to code on the go.
