Apple Maps has updated its Acknowledgements Page as of 10/22/15 to include Foursquare as a supplier of business listings data. About two years ago there had been some confusion about whether or not Foursquare was in cahoots with Apple Maps. Nice to see this finally confirmed. I have not seen an example of Foursquare data on an Apple Maps listing but I imagine it looks just like the Yelp integration.
This is pretty great news for Foursquare. Everything I have heard from other Apple Maps data suppliers is that the traffic to these listings has been accelerating at a rapid clip – Apple apparently provides data providers traffic data on their listings – so this provides Foursquare with a great reason for businesses to engage with them.
