iOS/Mac: Command-C is one of the better apps for sharing data between iOS and Mac. It recently added the ability to share clipboard data between Macs and now includes a full clipboard history.
The initial release of Command-C was handy enough as just a way to transfer stuff like links, photos, or text between your phone and your computer, but now it’s more of a hub for quickly sharing all that between devices in general. Now, you can easily share all those same things between Macs, and the clipboard history means you can share multiple items between different devices easily. Plenty of apps can send an item or two between your computer and your iOS device, but Command-C feels more like a system for sharing in general.
