Getting around

Common questions

Do I need an internet connection? No. Everything is inside the app.

I can't hear the tours. Check that your device isn't on silent and the volume is up.

Where does the information come from? NASA Blue Marble imagery, Natural Earth, Eurostat, the World Bank, the United Nations, the plate model of Müller et al. (2025), and published historical sources. Each globe's information panel lists its sources.
