Foldmetry: Spatial Reasoning

About this app

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. PRACTICE YOUR WAY WITH FOLDMETRY PRO Unlock all 36 guided lessons, full ten-question Mistake Review, unlimited practice at difficulty levels 1–10, selectable session lengths, and complete training history. Choose an annual subscription with a 7-day free trial for eligible customers, or unlock Pro with a one-time lifetime purchase. Pricing and eligibility appear in the App Store purchase sheet.

Build a lasting spatial practice with six guided learning paths, 36 named lessons, star-based mastery, and a new Cross Sections mode. Missed questions now return in Mistake Review, and Paper Folding includes 137 licensed animation-based challenges. We also expanded advanced generators with all 11 cube nets, new viewpoints, denser structures, exposed-surface questions, four-fold paper patterns, and complete Simplified Chinese support.
