A really easy to use and effective service for creating iOS and Android prototypes. The interface is really fast and simple to use with lots of drag-and-drop elements and options for transitions and animations. Scrolling in the completed prototypes feels really natural and you can even fix headers and footers for navigation bars, tab bars and toolbars. Flinto isn’t cheap at $20/month but you can try it for free for 30 days.
