the Fitbit mobile app
Display topographic maps, satellite images and road maps with cycle and hiking trails. 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.
Please watch the video:
The Fitbit app "Map Chart" can be used without connection to your phone.
But you need the phone app "Map Chart Mosaic" to download new maps to your watch (available in iPhone App Store and Google Play Store).
On the Fitbit app: tap the Menu button in the upper left corner and then the Download button to download new maps from your phone.
The Fitbit "Sync" step, shown in the video, is very important. Don't skip it and make sure that the Fitbit app "Map Chart" is closed during the Sync.
Please be patient when moving the map position, the Fitbit is slow and sometimes it hangs for several seconds.
