MapTag is a mobile app that brings the classic game of tag (捉人) into the real world using live location sharing. Designed for friends who want to play games like tag or hide-and-seek outdoors, the app shows everyone’s position on a map and assigns roles like tagger or runner. It’s fun, fast, and feels like a real-time multiplayer game — but in real life.

Right now, my friends and I use WeChat’s location sharing to play tag, but it’s hard to keep track of who is “it,” and there’s no structure or rules. MapTag solves this by:

• Clearly showing who is the tagger
• Making it easy to join a game room
• Offering multiple exciting game modes
• Adding fun and energy to real-world play

• Live map with moving players
• Game rooms: join by PIN or QR code
• Multiple modes: classic tag, infection, elimination, team tag
• Tag alerts: sounds and vibrations when you’re tagged
• Simple and clean design so anyone can use it easily

We want MapTag to be:

• The go-to app for outdoor group games
• A way to turn any park or school campus into a playground
• A fun, safe, and exclusive experience for close friends

• Middle and high school students
• Groups of friends looking for fun after school or on weekends
• Especially focused on users in China, starting with our own friend groups in Shanghai

MapTag 地图捉人 is more than just a tag game — it’s a new way to connect, play, and move in the real world. It’s simple, social, and built for fun. Let’s bring the joy of chasing each other back — with a modern twist.
