Redesign challenge: redesigning UX / UI of »willhaben«, Austrias certified ads app, in 48hrs. With over 9 million active ads online, »willhaben« is Austrias oldest and best-known platform for private certified ads. Usability and design haven’t changed much over the past decade, so both had to be modernized in a subtle way. Frequent users now can still find their way around their favorite platform while still feeling the refreshed look.
