You remember the moment you knew: I want to be up there. Above the clouds, hand on the sidestick, the whole world small beneath you. Between you and that moment stands a single day. One assessment that decides. And the helpless feeling that comes from not knowing what's really waiting for you. DLR Exam Trainer takes that feeling away. A few minutes a day, and you grow calmer. What felt overwhelming at first becomes familiar. Tension turns into focus. And on test day you don't hope you can do it. You know you can. No account. No cloud. Everything stays on your device. Just you and your preparation, in your language, at your pace. Your seat in the cockpit doesn't begin on test day. It begins today.

Practise spatial skills for 11+ non-verbal reasoning and CAT4-style spatial tasks. Preparing for grammar school or independent school assessments? Foldmetry offers short, focused practice in visualising shapes, understanding folds, and reasoning in 3D. Use it alongside your wider preparation: it is not a complete 11+ or CAT4 course and does not reproduce official tests. 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. TIMED EXAM-STYLE PRACTICE With Pro, try 12 mixed questions across all six skills, with 40 seconds per question. Review accuracy and response time by skill to plan your next session. This is Foldmetry's own practice format, not an official exam simulation. 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. Restore purchases at any time from Settings. 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. CAT4 is a GL Assessment test; Foldmetry is not affiliated with or endorsed by GL Assessment.
