Takes at least some of the sting out of regexes - I love regular expressions; when applied correctly, they can greatly simplify your code as you search for/parse/replace text. They can be a real pain, though, as they become more complex. Patterns make getting your regexes correct a lot easier. The interactive highlighting makes debugging your regexes simpler--you can back up and go forward to see where you've gone awry. Great tool. Would love to see support for capture groups.

Lots of potential, but very aggravating - I got this app to assist with constructing Regex terms. While it holds a lot of promise, there are two critical flaws. 1) There’s no way to save your work. By itself, that’s not a big deal. It becomes a big deal when the app crashes for no apparent reason. I’ve had the thing crash twice in the past 15 minutes after I’m close to getting a term done. If I had hair to pull out, I would. I hope the developer has Crashlytics installed so he/she can fix whatever the problem is.
Enjoyable Way Experiment & Learn - I’ve used regular expressions off and on for the past few decades - they are indispensable for certain tasks, and huge time savers in others. But I don’t use them constantly, which means I often need a quick refresher to get things working just right. That’s where this nicely crafted app comes in. I find it a quick, and intuitive way to re-familiarize myself with the arcane workings of regex expressions. My compliments to Nikolai Krill for creating this gem!
Good… except for the fact that it crashes... - Very nice interface and intuitive… but after several sudden application crashes on my MB Pro running El Capitan, I have had to give up and purchased a competitor’s application instead.
