About this app
Regex Tester is a fast, offline-friendly tool for building and debugging regular expressions right on your phone.
FEATURES
• Live matching — results update the moment you type, with every match and capturing group highlighted in color.
• Flags — toggle i (ignore case), m (multiline), s (dot matches newline), x (comments) and u (unicode character classes).
• Replace mode — preview a full replace-all using $1 group back-references.
• Match details — exact ranges and per-group values, with one-tap copy and share.
• Save patterns — keep frequently used patterns and reload them with a tap.
• Quick-insert buttons — drop common tokens (\d, \w, \s, (), [], …) at the cursor.
• Cheat sheet — a built-in reference for common regex tokens.
• English and Korean.
Matching uses the standard Java/Android regular-expression engine. Patterns you save stay on your device and are never uploaded.
