You're absolutely right, we're working on an additional info about technical side of this feature (as a response to comments). Showing the app before signing up is something that we're constantly thinking about. Probably it's about the time to make it comes true. My apologizes for the inconvenience. Moqups.com is great, but it's really focused on a different problem. UXPin - The UX Design App (http://uxpin.com http://uxpin.com) helps teams fighting for the best UX Design possible of their web&mobile apps, during whole design process. You can create wireframes, interactive prototypes, upload requirements, personas, visual design - and discuss each deliverable in one place. ps. We were launched way before Moqups :)
