As someone who has multiple iOS and Android devices at home, I can tell you that keeping all the cables and wires organized is such a hassle. Nothing is more frustrating than dealing with tangled cables anyway. The iShell is designed to address this issue. It is a smart winder that can partially and fully wind cables. It easily detaches from your cables, so it does not get in the way.
All you need to do is fold your cable in half, place it on the hook of the winder, push the appropriate button, and go. Full unwinding is pretty straight forward too.
iShell is suitable for iPhone and Android cables. A simple solution that keeps your cords untangled. You can support this project on Kickstarter.
