Fog of World is the first app that brings the fog of war idea into the real world map back in 2012 and provides free updates since then.
Fog of World remains the best app to render the fog overlay and is the only app that shows you high-resolution tracks. Don't believe it? Download the copycat apps and compare the results with Fog of World screenshots.
No other copycats can show the tracks with seamless thickness changes while zooming in and zooming out the map.
There is no user account of Fog of World. All of your data are saved in your device. You have 100% privacy.
You can sync or back up your data to iCloud, Dropbox, Google Drive, OneDrive, and Nutstore. But only you have access to them. We don't.
The database is designed to use as little storage as possible while providing high performance.
Fog of World is the only app that truly works around the world since China uses the GCJ-02 coordinate system due to political reasons. Other copycats either work correctly in China or the rest of the world, but not both.
Fog of World was chosen as the App of the Day by Apple in 137 countries.
