User Reviews for RegEx Lab: Regular Expressions

The best regex editor hands down

This app is a must if you need to whip up a regular expression without wasting time. It allows you to easily craft a collection of regex’s of varying techniques with individual sample source data. The developer is very responsive and generous to give this tool away for free.

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.

Very Useful!

This app does exactly what it says, and does it well. Beautiful clean design. The live highlighting of group matches in arbitrary text is awesome. And I very much appreciate the integrated documentation/cheatsheet. Definitely recommend this app!

Good Tool

I would give it 5 stars, but a few bugs have irked me. The import functionality is very broken, I am unable to hide the keyboard to press continue, would love to read in files, not copy paste them, corrected errors remain highlighted in red, but definitely a solid and helpful app.

Works as well as regex101

It’s so refreshing to have something that works on mobile. I love using the shortcuts app, so this is handy when I’m away from home. I could use regex101 on safari, but this app saves loads of time.

Handy, Educational, Enjoyable

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

Great RegEx tool!

I have been playing with regular expressions for almost 40 years, and I have relearned it over a dozen times. This is a very nice implementation for extracting data from text. I find it useful for doing simple tasks and practicing/learning.

The best app I have found for working with regular expressions

This app is constantly improving and is the best app that I have found in its category of working with regular expressions. Thanks to the developer for such a useful app.

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.

Fantastic tool to have in hand

While I am not a pro using RegEx, I quick test on this App before writing something on my computer. It’s easier and faster rather than run the script every time. And since I (sadly) live with my phone next to me it has just become a fun pass time even if I don’t need to them... By doing (rather than reading the theory) you learn so much more and if you are like me that has just started with RegEx, having an app like this will help you in the process of getting your feet wet! Highly recommended
