No longer works

Unchanged since late 2014, iOS changes have made this app pointless: it only saves the most recent clip to the clipboard, and only then when you switch to it. There are other apps that at least have an entry in the sharing panel so one doesnt have to switch apps to clip more than one item at a time. Might still work on older iOS devices.
