An OS X app for creating mobile app prototypes with animations, gestures and scrolling. Flinto for Mac goes way beyond the original online version of Flinto by letting you create anything from simple tap-through prototypes, to comprehensive prototypes with impressive interactions. It requires no programming or timelines in order to create slick gestures and animations including custom spring or cubic-bezier easing, and your designs can be viewed in realtime on your iOS device with the companion app.
