Why TrueSize?
Traditional flat maps can significantly distort the apparent size of countries and regions, especially near the poles. TrueSize uses spherical geometry to provide more realistic size comparisons while letting you freely move and explore territories around the globe.

From the creators of TrueSize.net, the official TrueSize app brings interactive geography tools, hundreds of thousands of regions, historical maps, games, measurements, and custom geographic data to your device.

Rediscover the world as it truly appears - clearly, accurately, and interactively.
