We are launching Xiffe today. Xiffe is mobile prototyping in a jiffy.<p>Xiffe lets you create prototypes for your apps in a xiffe using a simple drag-drop web interface. All your data is stored on the web making it easy to access anywhere on the internet. You can even access the prototypes on your iPhone to see how the app would look on an actual iPhone. No using Photoshop or Illustrator or Powerpoint, digging through layers and getting the right components. Just drag-drop components on the canvas and you are done.<p>Xiffe offers a little extra compared to other prototyping tools available on the internet. • iOS 7 compatible design library - Xiffe provides the complete iOS 7 flat UI library along with the standard skeuomorphic graphical elements - bars, buttons, keyboard, pickers etc. • Customization - Unlike most other mockup tools where you can change only basic properties for an element, with Xiffe, you get complete control of the elements to closely match the properties that Apple provides for its controls. So you can control the elements to the same levels that you can with Apple Xcode • Icon sets - Xiffe provides you with a large icon set. We have included vector icons from Font Awesome that can instantly be customized by you for both size and color. • App previewer - You can simulate an entire app workflow by linking screens through button clicks and specifying transitions between screens. So your clients and collaborators can see exactly how data will move through the app. • Collaboration - Share the app with anyone using Xiffe so you can collaborate in real time.<p>With this version, we are releasing only the iOS prototyping tool. Other platforms will be added soon with later releases. We have Android and Windows 8 in the works already.<p>We are still in beta and continuously improving our design and user experience. Try out Xiffe and do send us your feedback.
