Swarm, a dedicated check-in app by Foursquare, has received a tremendously useful update Friday which makes it dead simple to check in to your favorite locations right from your Lock screen without even opening the app, thanks to a brand new Notification Center widget available on iOS 8 devices.
The Swarm widget in the 1.3 update also gives you an at-a-glance view of a few of your friends who are especially close, helping you get a sense of who’s around.
