App is great
The app is amazing and works great. The latest update is making things better than ever before! Thanks for the great work!
United StatesBeware: touch first app
The developer has put no effort into the Mac version.
United StatesApp is great but needs updates
The app is amazing and works great for the most part. However, there are some needed updates. When creating a new expression to test, it takes a long time for the load screen to go away. Also, I find that often the "select this match" option from the list view doesn't work to take me there. It gets close but the match it was taking me to isn't visible on the screen
United Statesmy goto
sometimes regex apps and websites over complicate the interface making it tiresome looking at. i goto this app because it gets the job done and i'm not annoyed.
United StatesGreat 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.
United StatesThe best of the (many) Regex apps
Most regex apps I've tried are good for only testing whether your expression is valid, etc. This one goes further with find-and-replace and outputing capture groups. I love this app so much I'm not even going to ding it for how much I hate its thematic color! This app makes it easy to quickly select the output and copy it to run a new regex on it. There's a lovely button that selects the whole output for you so you can easily copy and paste it wherever. (Suggestion: Is it possible to add a button that not only selects the whole output but also copies and replaces the text on the previous screen, i.e., the un-regexed stuff, if that makes sense?)
United StatesSuper helpful tool!!!
Wow this app is great! I’m just learning RegEx and it’s so much easier to see instant feedback on these cryptic codes.

• A big change to how text highlight logic works. It should not provide much better performance and reliability. • Capture group coloring used to start with red, which was too harsh, it is now moved towards the end of the list of colors. • Removed the "Created" message which appears on screen when a new regex is added. • Added a "Select all" button for the test text. • Fixed an issue where some text fields would be too "smart" and change characters such as `...` to `…` or `"` to `“`. • Removed old third-party frameworks and switched to native code, which makes the app size smaller and improves performance.
