### 5/5 — Feature request: sorting, categories

*2026-06-27*

Hello, can you add the ability for one to sort the titles of the regexes alphabetically? Could you also maybe add a tagging and/or folder feature to sort into categories? Thank you

**Developer response:** Yes, will do. Thank you for your feedback.

### 4/5 — Good basics, lacks replace versatility

*2026-02-14*

The app has all the basic functionality I needed. presets, find/replace. The text highlight is very basic, wish it was multiple colors, so i can see exactly what regex is selecting. 
Also I can’t type linebreak “\n” and other escape characters in ‘replace’. The workaround for now is to select (\n) in find and then put it back with $1. Maybe there are solutions for that, but it’d be nice to have by default.

**Developer response:** Thanks so much for the feedback — glad the app is covering the basics you need!

About escape sequences in the Replace field: you’re right that \n, \t, and similar characters weren’t applied as real control characters. That’s fixed in the next version, so you can type them directly in the substitution template without the $1 workaround.

Appreciate you taking the time to write this up — it really helps.

### 1/5 — Join

*2024-07-20*

Very bad

### 3/5 — I want to like it

*2024-02-23*

... but the usability (at least on macOS) is not good. It doesn't automatically update to show if your pattern matches. You have to click on "Options" or somewhere else in the UI to make it update. Sometimes it simply doesn't update or show your pattern at all, even though it is correct.

This makes it not at all useful in trying to find the regex you need. It's rather frustrating.

### 3/5 — First impression, I agree with the other guy, needs work.

*2024-01-24*

But it works and works pretty decent. Major buy though: pressing ‘return’ crashes the app when typing in the ‘evaluation text’ area. I lost my regex like that :( Pasting a value in with new lines works fine though. 

Another bug is that if your regex is line enough to wrap to the next line, when you delete someone at the start of it, making it short enough to unwrap back into a single line, the cursor moves to the end of the regex and you start removing characters from the end instead of where your cursor was initially

### 5/5 — 删除示例文字时会闪退

*2023-12-10*

希望开发者修复一下iOS版本

### 5/5 — 非常好用

*2023-09-03*

自己平时有用正则验证的需要，这个App完美解决，感恩！

### 3/5 — на маке подвисает

*2023-08-22*

все бы хорошо, но на маке частенько виснет наглухо

### 2/5 — RegEx  v0.6.3

*2022-01-27*

I click on an entry and 9/10 times it stays blank, if I force quit and try again then eventually I can get the right hand window to populate and then use it.
It never saves the sample text or substitution fields.
Very poor.

### 5/5 — Perfect and Cheap!

*2022-01-02*

Great place to work on regular expressions on mobile. I use it for Shortcuts and this does everything I need. And it looks nice doing it!

## Version history (last 5 releases)

### 1.4 — 2026-08-15

• Organize your patterns into categories — assign them right in the editor, sync them across devices, and manage the list anytime. Deleting a category never deletes your regexes.

### 1.3 — 2026-08-01

• Substitution templates now expand escape sequences like \n, \t, and \r - typing \n inserts a real newline instead of the letter "n".
• Tap a match in the sample matches list to flash its text in the sample field.
