## What is RegEx Tester?

RegEx Tester is a focused, lightweight tool for designing and validating regular expressions on iPhone and iPad.

Built natively with the latest version of SwiftUI, it delivers a smooth, modern interface that feels right at home on every device.

Create a new pattern from scratch or start with the built-in examples, then see results update as you type. Instant match counts, highlighted previews and clear validity indicators help you refine your regex without switching apps.

what you can do
• store an unlimited collection of custom patterns
• search, sort and edit patterns at any time
• duplicate the demo library or delete it to stay clutter-free
• test against multiline input with live highlighting
• copy any pattern or match to the clipboard in a tap
• export or import patterns as JSON for backup and sharing
• work entirely offline; nothing leaves your device

why it’s different
• clean interface, no ads or tracking
• built in the latest SwiftUI for performance and future-proofing
• fast, on-device processing powered by Apple’s NSRegularExpression
• debounced testing keeps the UI responsive, even with large text
• full accessibility support and dynamic type
• english and italian localisations included

RegEx Tester is free to use with no hidden fees. Download it today and build better regular expressions, faster.
