UXPin wanted to make something special for the whole UX community, a tool that fits UxPin design process down to the last detail - and UxPin wanted to make it the professional tool for UX designers (something UxPin all needed). UxPin started with notepads in 2010 and they quickly grew in popularity, which is why UxPin decided in November 2011 to design a new, more complex notepad and an Online Wireframing & Documenting App to go with it. The rest is history in the making.
Proto.io is a silly-fast way to create fully interactive mobile app prototypes. Launched in 2011 and designed specifically for mobile, Proto.io can simulate everything an app can do. That includes interactive touch gestures, screen transitions and animations. 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. It is 100% web-based and offers a familiar and intuitive drag-and-drop User Interface (UI), with no coding required. It is ideal for User Experience professionals (UX), Interaction Designers (ID), mobile designers, coders, and app enthusiasts.
