iPhone Iterative Design: Convert Design Evolution video

Time-lapse video shows design evolution tweaks of taptaptap’s hit Convert iPhone app.

The original design session took place 390 days before it launched in the iPhone App Store. That’s 13 months of refinements. The result? Convert is currently ranked the #3 paid application in the App Store with 40,000+ sales in 2 weeks.

Good design takes time, focus and effort. It pays for itself.
