CtrlC is a free iPhone app developed by Chang Chin-Ming in the Business & Productivity category. It serves as a clipboard in a widget, allowing users to automatically copy and edit words. With CtrlC, all you need to do is copy words and pull down the Notification Center, and the app's widget will record the contents automatically.

One of the key features of CtrlC is its "Copy all" function, which combines all copied contents into one and allows users to paste it on any platform they wish to share. The app also supports iOS 8 widget, where users can see the text they copied from other places and easily record it by pressing the "+" button.

CtrlC can keep and list multiple texts, with support for text editing, sorting, and deletion. It allows users to save and load archives, with each archive capable of storing 10 texts. The app also introduces new user interface themes for customization.

With future updates, CtrlC promises to provide more and better customization features for its users. Overall, CtrlC is a useful, simple, and quick tool for managing copied texts on your iPhone.
