Swarm UI design & app screens

Swarm, from Foursquare, is a check-in app that gamifies visiting places, letting users log locations, earn coins and stickers, and compete with friends on a lifelong location diary.

The app blends a map, a check-in feed, and playful gamification with badges and leaderboards. Its colorful, sticker-driven personality stands out. It's a reference for location-based social UX, check-in flows, and reward and achievement systems.
