Proto.io Alternatives

Proto.io

Designed specifically for mobile, Proto.io can simulate everything an app can do. That includes interactive touch gestures, screen transitions and animating any UI item in a prototype. It is perhaps the only mobile prototyping tool that allows users to create realistic, sharable prototypes that work as a real app should and experience their prototype on the actual device. Proto.io is also the first prototyping tool to ever include custom device support, to allow prototyping for anything with a screen interface - from SmartTVs to refrigerators.

Proto.io is 100% web-based and offers a familiar and intuitive drag-and-drop user interface, with no coding required. Ideal for UX professionals, Interaction Designers, mobile and game designers, coders, and app enthusiasts.
