Doodle

Doodle is a simple Web app that allows people to “find a date and time for a group event.” It’s free and requires neither registration nor installation. With over 2 million users a month, it’s one of the most successful Web apps outside Silicon Valley.

iA was asked to redesign Doodle’s interface and brand identity. We began by evaluating the previous interface with a series of usability tests. Then we designed a sequence of updates that were checked and redesigned in a tightly coordinated evolutionary process between iA’s design team and the usability lab run by e&t in Zürich. This was the first time we developed a Web application in an environment so rich with usability testing. The high-approval rate of the previous user interface made the frequency of tests absolutely necessary.
