I love RegExr. It is the best app for regex I have ever found. However, this app is quite useless and it doesn't work offline.

It's useful. However, it is not an app. It's a hyperlink. I have to connect to internet to use the function.
Emmanuel Kimario
Very great App! so useful
Leo Lavarias
Probably this is best one I found over the internet. If there is a bad thing about this app, it is that it does not come out as the first result on Web store when I search for "regex"
Josiah Hudson
This webapp is really good. Beautiful UI, great instant highlighting & syntax help. Great work!
Wes Alvaro
It's only a shortcut, but the website is awesome for working with and referencing Regular Expressions.
Michæl Graves
Extremely useful and usable. Comes with Help, References, Examples, and Community submitted / voted on Expressions.

I like it. It's simple, it's easy to use, and it saves a heck of a nightmare researching all those Regex commands for the one that is "assumed" to work. No more having to create custom test cases in my code just to make sure it works properly! Woo!
Trevor Dunn
Nice! Realtime syntax highlighting and tooltips!
Shawn Blais
Love it
Lanny McNie
Super useful. Tooltips, syntax highlighting, and undo/redo are invaluable.
