Map Buddy: Find and Make Maps

Map Buddy™ lets you discover, subscribe, and create interactive maps.
Use it to find food trucks, garage sales, good coffee, and more! Plan your next friendly scavenger hunt or leave surprise notes for your loved ones.
Maps that you subscribe to are visible on your home map. Map Buddy is your one stop place to view all of the things that you find interesting in a single place.
Map Buddy comes with a curated list of automatically updated maps. This includes Earthquakes and data sourced from San Francisco municipal sources, such as 311, 911, and fire department calls. More curated maps are added constantly!
The Great Lakes Bay Region Alliance uses Map Buddy to host their STEM Passport program and to promote partnered STEM locations with Michigan students.
Note that Radar Chat has been renamed to Map Buddy! The functionality of the app hasn’t changed much: you can still use Map Buddy to leave digital messages attached to physical locations. However, we feel the new name better conveys the utility that people have found with the app, not to mention “Radar Chat” never really gave users the ability to “chat”.
