Map Chart Mosaic is a comprehensive offline mapping application designed for both smartphones and smartwatches. It offers users access to topographic maps, satellite images, GRIB weather forecasts, and road maps complete with cycling and hiking trails. The app supports nautical charts specifically for USA and Canada. Users can switch between different map sources to gather detailed information about any location. All map views are automatically saved in an offline cache, allowing users to view them without an internet connection.

In addition to offline map viewing, the app provides advanced features such as adding map markers and notes (e.g., parking locations), creating travel routes, recording GPS tracks, and sharing data as GPX files. Users can also obtain GPS travel information including speed, course, odometer readings, and estimated time of arrival (ETA). For weather updates, GRIB forecast maps can be downloaded via the internet, email, or Iridium Go satellite connections. The Wear OS version allows independent use on smartwatches, though new maps and data must be downloaded through the phone app.
