Mockup / Wireframe Your Mobile and Web Applications: Mobjectify

Mobjectify simplifies the task of getting up a quick mockup of your mobile website or webapp.

Use the bundled widgets, to generate a prototype for your site in just a few minutes. Which means you can experiment with actually running designs rather than paper layouts or wireframes.

No knowledge of coding in HTML or Javascript is required, but all your designs are styled using jQuery Mobile which means you can always build up to complex feature rich applications.
