Great Calendar, but foursquare for location destination is terrible

Ive been a longtime Calendars 5 user, going back to when it was Calendars+ and I love the viewing options offered by Readdle. The issue that drives me away however is the use of Foursquare for location identification. Every other Calendar product seems to be tied to google maps which is ideal for both business and residential locations. If this were user selectable or better yet if foursquare were abandoned entirely in favor of Google I would come back in a heartbeat.
The calendar itself rocks, but foursquare is garbage.
