Bringing pattern-matching joy to the masses, the long awaited update to Regexen has arrived. Now with more pixels than ever!

• Supports POSIX and Perl-compatible regex rules

• Matching highlight(s) update as you type your regex or target

What's New in Version 1.6

• Support for iPhone 5, 6, and 6+ screen sizes. Text entry areas now scale appropriately with screen size.
• Updated the underlying PCRE version to the latest release

Worth price, could be improved

Overall, this app is worth the price, but it falls short of what it could be (which would make me pay more willingly).

1) Make it more readable - the fonts used are too tiny and there is no way to change them that I could find. Tough when you have poor vision.

2) A real, built-in reference to regex soul be very helpful, along with a way to build expressions from it. I've been using regular expressions for over 20 years, and I still forget half the time what I'm doing...

There is potential here, and the author should be encouraged. Ignore the other review where the writer seems to think an editor command is necessary.
