The app supports nautical charts for USA and Canada, providing users with detailed location information by seamlessly switching between different map sources.

A key feature of Map Chart Mosaic is its offline capability. Maps are automatically cached on your device upon viewing, allowing access without an internet connection. Users can download maps to their smartwatches for phone-free navigation. Additional functionalities include adding map markers, creating travel routes, recording GPS tracks, and sharing data in GPX format. The app also provides essential GPS travel information such as speed, course, and estimated time of arrival.

This app is particularly useful for outdoor enthusiasts who require reliable map access in areas with limited connectivity. By offering extensive offline functionality and supporting Wear OS devices, Map Chart Mosaic ensures users maintain access to critical navigation data at all times.
