Code, compile, run, and debug on Android
NanoIDE helps you run Java on Android and run Kotlin on Android with an embedded offline compiler. You can test snippets, practise algorithms, verify homework, and debug logic errors without switching devices. The built-in Java debugger and Kotlin debugger make it easier to follow program flow, inspect variables, and fix mistakes faster.

A mobile first programming app
This programming app is designed for students, beginner programmers, Android developers, competitive programmers, and developers who do not always have a laptop nearby. Use it as a Java IDE for coursework, a Kotlin IDE for learning modern syntax, an offline compiler for travel or low connectivity environments, or a code editor for quick edits on the go.

Learn Java, Learn Kotlin, and practise DSA
NanoIDE is more than a compiler. Use the built-in lessons to learn Java, learn Kotlin, and improve problem-solving with DSA tutorial content you can read, run, and modify instantly. This makes coding practice more interactive than static notes because you can edit the sample code and see the output immediately.

Built for real mobile workflows
Create projects, organise files, save work in your preferred folders, and keep code lightweight on low end devices. Git support helps you move from solo practice to real developer workflows. Whether you are preparing for a class test, revising data structures, or prototyping an idea on the bus, NanoIDE keeps your coding environment ready.

Use NanoIDE for
• Java compiler tasks and Java coding practice
• Kotlin compiler exercises and Kotlin learning
• Offline debugging on Android
• Mobile coding IDE workflows
• Code editing and project management on the go
• DSA tutorial revision and interview preparation
