Mockups

Rapid wireframing tool

Details

Mockups reproduces the experience of sketching interfaces on a whiteboard, but using your computer, so they're easier to share, modify, and get honest feedback on. Wireframes made with Mockups look like sketches, so stakeholders won't get distracted by little details, and can focus on what's really important instead.
