Rapidly create beautiful, high-fidelity mockups of iOS, iPad and iPhone applications with Mocks. Mocks is a modern, native app for OS X that gives you special tools to design mockups of iOS applications and screens.
Mocks comes with a built-in collection of graphics depicting iOS UI controls and widgets (like buttons, toolbars, and text fields). Drag these controls from the Library palette on the left to the central Canvas area where you compose your mockups. Alignment guides (both automatic, and user-created) help you keep your designs in line.
Every Mocks composition is a multi-page document supporting Apple's iCloud Document Storage, Autosave, Version Browsing, and Full-Screen features in Lion and Mountain Lion. Page thumbnails appear in a vertical palette on the far left of every window, giving you an overview of the contents of all pages simultaneously.
