## What is Regexcellent?

Learn regular expressions by writing them. Regexcellent combines a guided course, a live regex playground, and short challenges in a native app that works offline.

LEARN AT YOUR OWN PACE
Work through 40 interactive lessons in 8 modules, from literal matches and character classes to groups, backreferences, lookarounds, and practical recipes. Type patterns against sample text, see the matches, and use progressive hints when you need a hand.

EXPERIMENT IN THE PLAYGROUND
Test patterns with live match highlighting and capture details. Explore token-by-token explanations, toggle matching flags, and save useful patterns on your device. Export supported patterns as Swift, Kotlin, JavaScript, or Python snippets, with warnings when regex engines differ or a translation is unsupported.

PRACTICE WITH REGEX GOLF
Try 24 challenges and a daily rotating puzzle. Find a working solution, then make it shorter to improve your score.

KEEP A REFERENCE CLOSE
Search common regex tokens and open working examples in the Playground.

BUILD A PRACTICE HABIT
Track completed lessons, module badges, and your practice streak. Enable an optional local reminder when it suits you.

MAKE IT YOURS
Choose System, Light or Dark appearance. Swipe through onboarding with navigation controls always within reach, and see your module badges in a clear three-column layout.

OPTIONAL ICLOUD SYNC
Keep learning progress and saved patterns in sync across your iPhone, iPad and Mac using the same Apple Account. Sync is off until you enable it and confirm what will be copied to iCloud. 

FREE TO LEARN
Every lesson and feature is free. The course, reference, challenges and regex engine work offline without an account. There are no ads, subscriptions or paid feature unlocks. Optional one-time App Store tips support development and unlock nothing. Sync and tips require internet and the corresponding Apple account.

Built with SwiftUI for iPhone and iPad, with layouts that adapt to your screen.

Regexcellent is for students, developers, and anyone who wants to understand the patterns they use. Start with your first match or use the Playground to explore a pattern of your own.
