What works well on a phone
- Concepts. Variables, loops, functions, data structures and how programs are organised are ideas first and typing second.
- Reading code. Most professional programming is reading. A phone is a good place to practise predicting what code does.
- Short exercises. Small, focused tasks that check one idea at a time.
- Revision. Checkpoints and flashcards fit naturally into spare minutes.
- Listening. Hearing a topic explained on the move. See How to study by listening.
What needs a computer
- Projects with many files. Navigating a real project is much easier with a big screen.
- Your tools. A terminal, a debugger, version control and a proper editor.
- Long typing sessions. Writing hundreds of lines on a phone keyboard is slow and frustrating.
A split that keeps you moving
| On the phone | At a computer |
|---|---|
| Learn the idea of a level | Build something with it |
| Read and predict code | Write and run larger programs |
| Checkpoint and flashcards | Debug your own mistakes |
| Listen on the move | Work through a real project |
If you do not have a computer yet, you can still get through the foundations of a language on the phone. By the time you need a computer, you will know exactly what to do with it.

Frequently asked questions
Can I learn to code using only my phone?
You can learn the foundations of a language on a phone: concepts, reading code, short exercises and revision. Larger projects and professional tools are much easier on a computer.
What is the best programming language to learn on a phone?
Python and JavaScript are good first choices: readable, widely used, and taught well in short lessons. See the guide to learning Python from scratch.
Which app teaches coding on a phone?
LoWisa teaches 37 programming languages on Google Play and the App Store, lesson by lesson, with Level 0 of every course free.
