One of my favorite wireframing tools is Justinmind's Prototyper, where not only can I rapidly create wireframes, but I can turn them into functional prototypes. For this client, I created their entire backend product (which I can't show in full here) as a complete prototype. Sometimes, the best way to convey to a client the behavior of a UI/UX design is to show them and have them interact with the product, which has the amazing result of bringing up questions and issues that would never have been thought of with static wireframes. In the case of this project, with some pretty interesting usability challenges that we had to overcome, prototyping was essential.
Once the prototypes were approved, we then moved into visual design which had to match the look of Duracell. I created the look-and-feel, all the screens, and the color palette with the exception of the calendar and week view, for which I employed some help and provided the wireframes and creative direction, as well as applied some final touches. You can see the visual design here.
