Foursquare’s social check-in app Swarm has seen a nice update over the weekend for most users, bringing a lot of changes and new information for users. The update is version 4.0 for those keeping score at home and it started rolling out to the Google Play Store on Friday. Most users by this point probably have the update via an OTA but if you don’t, you should see it any time. For those who aren’t familiar with Swarm, it is an app where you can check into places and earn virtual coins as you climb the ranks amongst your friends. These coins can be spent on stickers which multiply your score throughout the day or week.
