Description
This is a lightweight Amazfit watch quick app, open-source on GitHub. It uses the watch’s GPS to show real-time latitude/longitude and auto-convert them to Maidenhead Locator grid coordinates—essential for amateur radio enthusiasts. Beyond ham radio, it enables position reporting via maritime Channel 16 when offline outdoors/at sea, a lifesaver for outdoor adventurers.
