THEY : Avoid the Shopping Crowds

THEY creates a fun iOS/Android/desktop appthat will help you avoid the crowds during your Christmas shopping. Using social media check-ins, the app tells you about the crowd level in Amsterdam's four main shopping areas.

Similar to Neiman's "Go Crowdless" app, this will definitely at least help you avoid the sort of people that check in on social media. Which might be a good thing to some people at least.
