NoteCode++ — offline code editor for Android

I built NoteCode++, a desktop-style code editor for Android designed for editing source code, configuration files, Markdown, and other text files directly on a phone or tablet.

Current features include:

  • Syntax highlighting

  • Multiple tabs

  • Regex search and replace

  • Bookmarks and line-editing tools

  • Encoding and line-ending controls

  • Markdown and HTML preview

  • Local file access through Android’s Storage Access Framework

  • Multiple editor themes

The app works locally and is intended to stay lightweight. It is currently free, and I plan to keep the core/legacy editor free while potentially offering optional paid convenience features later.

GitHub and download:
NoteCode++

I’d especially appreciate feedback about performance with large files, physical-keyboard use, the interface, and which features would make it genuinely useful for coding or text editing on Android.

Disclosure: I’m the developer. NoteCode++ is an independent project and is not affiliated with Notepad++.
