• Format JSON
• Create and decode short URLs
• Convert and preview RGB/HEX colors
• Browse system fonts

QR codes and cross-device transfer

• Scan or generate QR codes
• Transfer text, images, and files between a browser and your iPhone or iPad on the same local network
• Preview and save images, or open files with the system share sheet
• Temporary images and files are removed when the transfer session ends

Quick Note

• Save text in seconds
• Browse a dedicated history page with update times
• Tap any record to load it back into the editor

The app supports English and Simplified Chinese and follows your system language automatically.
