As someone who frequently copies and pastes, I rely on clipboard managers to get work done on my Mac. Quite often, when I copy something, I forget to immediately paste it elsewhere. Without a clipboard manager, that item would be lost forever the instant I copied something else. But thanks to these apps, I can keep track of everything I've copied and retrieve things from my clipboard history easily. I've long wished for something similar on the iPhone, and recently, some clever app developers...
