Grapevine is an app that shows you where social groups want to go. In the app, you can create and join ‘circles’ which reflect the groups of people you hang out with irl. A circle could be be you and some friends, or a club or society at uni.

Then there's the feed of events created by other people (or you!). For each event you can opt-in or out by swiping right or left. You can also invite other circles or tap the "Who's In" button if you want to have a peek at what circles want to go. The cool thing is that Grapevine sorts the events in your feed by social groups relevant to you. This ensures that you see events that matter!
