    This app is a good way to experiment with Regular Expressions. It's saved me lots of time when building Shortcuts. And it keeps getting better and better with periodic upgrades. My thanks to the developer!

    While I have only touched the surface. The design of this app is really great. Love the color coded grouping.
  • Useful app when working with regular expressions

    By José Alburquerque
    The app is really stable. Multiple regular expressions with text to be matched are saved from session to session. A really useful app when working with regular expressions..

    Just as the title says, simple, to the point and does what it says on the box and probably more!
  • Great for practicing expressions on the go

    I’ve never written a review on the App Store before, but I reached out to the developer and requested an export feature. Sure enough - it shows up in the next update! Regular Expressions are new to me, so it’s important that I can take my learning and practice on the go. This app is perfect for that. No fuss - just works.
  • Great, full-featured regex tool

    I wanted to test a regex but didn’t want to connect to work to get a Linux window. Downloaded this app and voila. You can write your regex and write your data, both of which you can save, and it highlights the matches or does the replacements. It’s got examples and reference information. Font size is adjustable.
  • Best app for CS

    By kandarpjajvalia
    I was in my class and wanted to use an iOS app that had regular expression, I don’t like web apps as they don’t work smoothly on mobile webpages. I’m in my class right now and using this app, super smooth and best. I have my notes on notability on the left and this app on the right. I can follow my notes easily.
  • Best app of this kind in the app store
