About

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. [Specifications] ・Intuitive Controls: A refined, quiet experience of drawing a single line on the canvas. ・Precision Scoring: Calculates deviations from the actual map based on shape, position, and area. ・Vast Map Data: Comprehensive coverage of regions across Japan, the US, China, and the globe. ・Global Ranking: Connect to the worldwide leaderboard and battle for the top rank. ・Immersive Design: A minimalist, distraction-free interface fully optimized for Dark Mode.
