WhenToCop? is the number one sneaker information application in France. Founded in 2020, WhenToCop? is a media that aims to make sneaker fans' lives easier by making information and resale accessible. We offer a service via both our website and our iOS/Android app to our users by providing them with essential information for each pair of sneakers. We show the release date, time and price, an index and resale price estimates, and all the retailers where the pair can be purchased. More than 200,000 people have already downloaded our app and we are followed by more than 100,000 people on social networks. Thus, we become step by step, the reference in the French sneakers news.
