After the HOW magazine team completes an issue, I then translate it into a custom experience for the iPad and iPhone using Adobe DPS. During my time with HOW, I redesigned the iPad and worked with development to launch the iPhone.
The intent of the design was to provide the user with a more comfortable and visual reading experience. This was achieved by making sure type was large enough on both screens and adding image slideshows and hyperlinks.
