Briefs: A Cocoa Touch Framework for Live Wireframes – Lifeless mockups don’t tell the entire story, but you don’t have time to build a prototype. We’ve been there, too. MartianCraft’s clients are some of the most demanding companies in the world. Your clients need a clear picture, so give them something to touch. Create a brief and you can hand your designs to people in a way they can play with. You can quickly incorporate their feedback and create new iterations quickly for them to retest. Before you know it, you’ve cut months of back and forth from your schedule without spending a dime on development.
