Quite helpful!

内置的截图格式非主流，这个是png，很适合网络上传。咔嚓的声音颇有趣，还可以设置默认存储文件夹，很好很高效。

The inserted "Grab" by Apple only outputs TIFF pictures, but this one is png, suitable for uploading to popular domestic social networks. The voice "ka-cha" is cute, and it allows to set a default folder to store pictures, very convenient and efficient! Great app! Thanks!
