## What is Kodex?

Kodex is an advanced code editor which brings powerful and desktop-class editor features to your iPad or iPhone:

* Multi-caret editing, to quickly transform code selections.
* Regex search and replace, with template matching and replace-all-matches.
* Minimap which allows quick scroll navigation though the document.
* Multiple window support
* Syntax highlighting for over 150 languages.
* Trackpad support with custom gestures to add cursors (ctrl+shift+click).
* Auto complete feature (currently only for HTML).
* Add as many guide columns as you wish (default 80 and 120 characters).
* Configurable tab size (default 4 spaces), or insert spaces when pressing tab.
* Draw hints for invisible characters such as new lines, tabs, and spaces.
* Customizable key bindings, so you can configure Kodex to use the same key combos you are already used to.
* Kodex smartly preserves your open documents so that your work stays as you left it between launches.
* Light and Dark modes.

Kodex is integrated with the Files app, so you can easily open files from any other app, and from your iCloud documents folder.

You can launch Kodex QuickEdit from any file sharing view in any app to edit its contents without launching the main Kodex App (be aware this functionality depends on the host app implementing the sharing activity properly).

Included are 10 editor themes, and several monospaced fonts for code editing (you can install your own preferred fonts using system profiles). Font size and line spacing are adjustable, so you can configure Kodex to best fit your preferred screen size, arrangement, and orientation.

Kodex is not a compiler, and you can not build or run the code you edit from it. Think of Kodex as a NotePad++ or Sublime Text substitute for iPhone and iPad.

Kodex is currently optimized for external keyboards, such as Apple's Smart Keyboard for the iPad Pro, or any bluetooth/USB keyboard. More virtual keyboard features will be added in a future version.

### 1/5 — LOVED

*2026-08-14, version 1.4.2*

Loved

### 5/5 — Bug Report

*2026-07-21, version 1.4.2*

I really enjoy using your text editor app, thank you!However, I would like to report a bug. When I select a block of text and cut it, a part of the text right after the selected block disappears if the selection size exceeds a certain limit. This is a problem because it deletes text that I didn't actually select to cut.I hope this issue can be fixed soon. Thank you!

### 5/5 — Respects me as a user

*2026-07-07, version 1.4.2*

This is the ONLY app out of three dozen I have tested for various types of code editing or note taking that hasn’t shoved a billion ads in my face. And it has the features I want and is a great, simple, minimalist code editor. I love it guys and please keep up the great work!

### 5/5 — Parabéns

*2026-06-12, version 1.4.2*

Aplicativo muito bom! Parabéns Bruno pelo desenvolvimento desta ferramenta ótima para visualizar/editar código simples e eficiente.

### 1/5 — 어려움

*2026-06-07, version 1.4.2*

### 1/5 — TERRIBLE

*2026-03-07, version 1.4.2*

I have never had an app so CONfUsING worst app even my so assistance couldn’t find out what to do I need some help but still nothing i ended up deleting my app and getting a new one also good luck on your coding IM CODING A WEBSITE but this is NOT the right app to do it on unless you are a real GEEK 😂😂

### 5/5 — Excellent!

*2026-03-01, version 1.4.2*

Nice lean, low fat app with pretty much all the technical features I want in an iPad text editor. The only thing I can think of that it’s missing is a keyboard shortcut for commenting/uncommenting selections (usually Cmd-/). Great work :)

### 3/5 — Next to perfect

*2026-02-21, version 1.4.2*

Everything is fine, no distractions. The sublime text for iOS, but unusable: no room for the text!  The keyboard has so huge space wasted and the menu! The menu seems designed for a 33’ screen.  You have only 3 lines of your source code visible to work with

### 5/5 — Me encanto

*2026-02-18, version 1.4.2*

Puedo cambiar la versiónes de los mods de fnf

### 3/5 — Would be great

*2026-02-11, version 1.4.2*

This would be my favorite code editor, but the lack of a word wrap toggle makes it nearly useless to me.

### 1.3.2 — 2020-03-05

This patch update is packed with bug fixes and new features, some that have been requested for a while. As always, thank you for using Kodex and for your positive feedback. Happy coding!

New features:
- When multiple selected ranges are present, you can now drag on the drag handle of the main selection range to adjust the length of all selected text ranges.
- When multiple selected ranges are present, you can now tap on one of the selected ranges to make it the main selected range, and thus move the drag handles to that selected range.
- Added "Save Document As…" feature to allow saving the changed document to a new location without touching the existing file. This feature is most useful if used with autosave turned off.
- Added "Replace All" option to the search-replace feature.
- Added option to turn off displaying line numbers on the left side of the editor.
- Added "plain text" language in the syntax highlight picker to force disabling syntax highlighting.
- When using Control+Shift+Up/Down to add a new selection, or the "Add Caret Above/Below" navigation bar buttons, if the current cursor is a non-zero length selection, the new selection will attempt to match the length of that range

Fixes:
- Fixed bug that caused visual glitches on editor after changing line height
- Fixed bug that caused the selection ranges to be displayed at incorrect locations after changing font, font size, or line height
- Fixed bug that caused the wrong font size to be applied to the source code after changing editor themes
- Fix drawing highlighted text when searching
- Fix alignment of navbar items in the editor view
- Improved performance when handling very large files.
- Fix selection behavior when to using Command+Shift+Left/Right to expand selections to include the rest of the line, which would produce unexpected results depending on the previous movement of the selection cursor

### 1.3.1 — 2020-02-16

Fixed crash that would sometimes happen when deleting several lines using multi-caret mode.
Fix editor automatically replacing quotes and dashes with "prettier" versions that break code.
Improves highlighter engine to be more reliable, which should solve many crashes that happened during editing.
