Map Chart Mosaic

Offline maps for iPhone, Apple Watch, Fitbit or Garmin smart watch:
topographic maps, satellite images, GRIB weather forecast maps and road maps with cycle and hiking trails.
Nautical charts are currently only for USA and Canada available.

Please watch the video and read the FAQ:

Switch seamlessly between maps from different sources to get detailed information about a location.

Map views are automatically stored in an offline cache on your phone, so that you can view them later without an internet connection.

Download offline maps to Apple Watch or Fitbit smart watch and view them without connection to your phone.

Add map markers and travel routes to the offline maps (e.g. your current car parking location).
Create map travel routes. Record your GPS Track.
Share map marker, route and track data as GPX files.
Get GPS travel info: speed, course, odometer, route ETA (estimated time of arrival)...

Get GRIB weather forecast maps via Internet download, Email or Iridium Go satellite connection.

You can display the maps also on the Fitbit smart watch. But please don't expect the same maps app performance on the Fitbit as on a phone. The Fitbit is very slow and has very limited space.
The Fitbit phone app "Sync" step, shown in the video, is very important. Don't skip it and make sure that the watch app Map Chart is closed during the Sync.

Do NOT use the app for navigation or any other purpose that may result in personal injury or property damage. Use it at your own risk.
