Ask HN: Foursquare Alternative?

I like swarm / foursquare for logging locations I visit. What I used to like is that I could subscribe to the foursquare iCal feed and see my checkins on my calendar.

Foursquare has stopped supporting this feature. I have tried using other options (like IFTTT). But nothing works well.

Are there alternatives to foursquare, in particular, that support “subscribing” via calendars or let me visualize the time series of my checkins easily?
