## What is atlas12?

Reconstruct the contours of the world with your fingertips.

atlas12 is a drawing app that tests the absolute limits of your memory and precision.
Trace the silhouette of a given region freehand, and a proprietary algorithm will cross-reference it with actual map data. By analyzing deviations in shape, position, and area, your accuracy is visualized as a precise percentage.

Japanese prefectures, US states, Chinese provinces, and nations worldwide.
From familiar topographies to unknown borders, every map is directly linked to a global leaderboard.

Compete against everyone—from close friends to unseen rivals.
Achieve uncompromising precision and seize the top of the world.
