StickerHunt.io
Join the IRL sticker hunt game and find stickers in your city.
Overview
Pokémon GO proved people will walk miles for digital collectibles. StickerHunt.io takes that insight and applies it to something more personal: stickers placed by real people in real locations. Players find and collect stickers hidden in cities around the world, turning every walk into a treasure hunt and every neighborhood into a game board.
The Challenge
Location-based apps are notoriously hard to build well. GPS drains batteries. Maps are expensive. And the cold-start problem is brutal — a social game with no players is just an empty map. We had to:
- Build a location system reliable enough to feel magical, not frustrating
- Create engagement loops strong enough to survive the cold-start period
- Ship cross-platform (iOS, Android, web) without tripling the engineering effort
Technical Stack
- Mobile: React Native for cross-platform development
- Backend: Node.js with PostgreSQL
- Maps: Mapbox for location services
- Real-time: WebSockets for live updates
Key Features
Walk and Discover
Stickers appear as you explore. Geofencing triggers notify you when you're close — turning a commute into a game without demanding attention.
Collect, Compete, Connect
Follow other collectors, showcase your finds, and climb city leaderboards. The competitive layer keeps hunters coming back.
Play Anywhere, on Anything
Full cross-platform sync means you can check in on mobile and browse collections on the web. Your progress follows you.
Results
5,000+ active players, stickers placed across cities in multiple countries, and a community that grows organically through word-of-mouth. The best metric: players keep coming back — not because of push notifications, but because the game makes their daily walks more interesting.
Lessons Learned
- Nail the core loop first: social features and leaderboards mean nothing if the basic act of finding a sticker isn't satisfying
- Battery life is a feature: aggressive GPS kills adoption — we optimized for geofencing triggers over continuous tracking
- Organic growth is slow but durable: communities built through word-of-mouth are harder to start but impossible to fake
