So we build what you want to use. The plan is to build SHADOW for all three devices, but we need to select which one we develop first. So we wanted to give you, the users, a chance to tell us what devices you want to use SHADOW on. We will build in the order in which you fund, so if you want your device to come first, spread the word. UPDATE: As of September 24, iOS met its funding goal, and we started building it. Android and Windows: there's still time to rally your community to build SHADOW for your device next!
