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.

Verdict
The clearest difference is ads: Kodex at none against O's shown. O's advantage is rating (4.5 vs 4.2) and ratings volume (8.6K vs 208). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Kodex sells 1 one-off in-app purchase and O sells 23 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
O holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: O has 8.6K ratings behind it against 208, so its average is the more settled of the two. Written reviews split almost evenly too, at 63% and 63% positive.
Kodex ships an update monthly, O fortnightly. The most recent releases landed on October 29, 2026 and October 31, 2026 respectively.
