Volta
Volta is a lightweight electric circuit design application for Mac. It features a schematic editing tool and support for third-party circuit simulators. I'm planning a mobile version of Volta for the iPhone or the iPad. The mobile version will be able to share files with the Mac version and will have schematic editing capabilities but no simulator.

Volta is the successor of MI-SUGAR and is work in progress.
