## What is Foldmetry?

Build stronger spatial intuition, one focused session at a time.

Foldmetry turns six spatial-reasoning skills into clear, interactive exercises:

• Mental Rotation: recognize a solid after it turns in 3D
• Cube Nets: predict how a flat net folds into a cube
• Perspective Taking: visualize structures from another viewpoint
• Paper Folding: reverse folds and predict position patterns
• Block Assembly: count volume, missing cubes, and exposed faces
• Cross Sections: find exact slices through 3D structures

START FREE

Start all six paths, complete the first two lessons in each path, try a daily mixed session, and review up to three missed questions at a time. Best scores, stars, streaks, and recent progress stay on your device.

PRIVATE BY DESIGN

No account. No ads. No behavioral tracking across apps or websites. Your training history, mistake queue, and preferences remain on your device. Foldmetry uses privacy-friendly anonymous analytics (TelemetryDeck) to understand which features help; you can turn this off in Settings. Exercises and licensed paper-folding animations work offline; a network connection is used for App Store purchases and optional analytics.

Foldmetry is an independent educational practice tool. It does not measure IQ, provide medical advice, guarantee academic or exam results, or claim affiliation with any examination authority.
