Description
RegExpress is a full-featured regular expression workbench for iPhone, iPad, and Mac. Build, test, explain, debug, and save regex patterns in one native app, whether you are learning regex basics or preparing patterns for production code.

Test patterns live with match highlighting, capture group details, search and replace previews, and options for case sensitivity, multiline matching, dotAll, Unicode, sticky behavior, and more.

Choose the engine that matches your target stack: Swift RegexBuilder, NSRegularExpression, JavaScript/ECMAScript, Python, or PCRE2. Saved patterns keep their flavor so you can revisit them with the right behavior.

Understand complex expressions with rich explanations, token breakdowns, warnings, examples, AST details, performance metrics, catastrophic backtracking guidance, and visual railroad diagrams.

Build and organize a personal pattern library with folders, favorites, history, notes, smart search, export, import, deep links, and optional iCloud sync. Your data stays on device unless you enable iCloud.

Generate ready-to-use code snippets for Swift, JavaScript, Python, Java, C#, and Ruby. Share patterns, test suites, and library exports with teammates or move them into your own projects.

Practice and learn with interactive examples, regex reference material, daily puzzles, regex golf challenges, and guided tutorials. The free tier includes live testing, saved patterns, history, folders, search, basic export, and the first tutorial modules.

RegExpress Pro is a one-time purchase that unlocks unlimited saves and history, iCloud sync, advanced tutorials, test suites, visual debugging, pattern optimization, pattern comparison, visual diagrams, code generation, and more.

RegExpress works offline for core testing and learning features and supports English, Spanish, Brazilian Portuguese, and Simplified Chinese.
