Foldmetry: Spatial Reasoning

Mental Rotation & Cube Folding

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Train your 3D intuition in focused daily sessions. Rotate shapes, fold cube nets, switch viewpoints, unfold paper, and assemble blocks—entirely offline. Build stronger spatial intuition, one focused session at a time. Foldmetry turns five classic 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 — trace holes and cuts through folds • Block Assembly — complete and compare voxel constructions START FREE Learn every exercise type, practice introductory levels, complete a daily mixed session, and follow your recent progress. Questions are generated for repeatable practice rather than copied from a fixed test bank. PRACTICE YOUR WAY WITH FOLDMETRY PRO Unlock unlimited sessions, difficulty levels 4–10, 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.
