Tap Tap Tap, the makers of the iPhone app Convert, have posted a time-lapse video that chronicles the evolution of their wildly innovative user interface. Check out their own post (with great reader comments) here.
The video serves as a great testament to the benefits of an iterative approach to UI development and how far you can get if you really keep pushing, and refining, a design. So often we’re pressed into timelines that make this kind of iteration feel impossible but the ultimate success of this particular interface should serve a prime example of how designers needs room (and time) to do great design.
