Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

• The template library more than doubled: 33 ready-made patterns — now including IPv6, MAC addresses, JSON strings, JWT tokens, credit card numbers, and GPS coordinates — each with sample text. • New on iPad and Mac: quick actions in the detail pane let you start a new pattern or choose a template in one tap. • The username template now has tighter boundaries for more precise matches.
