Tally vs Foldmetry

Tally makes you faster at mental math — genuinely, measurably faster — with a few focused minutes a day. No childish games, no ads, no accounts. Just a beautifully quiet training room, an adaptive engine, and numbers that start obeying you. TRAINING THAT FITS YOU Every mode tracks its own skill rating. Answer quickly and correctly and the problems grow harder; struggle and they ease off. Tally aims to keep you around 80–85% accuracy — the zone where practice feels challenging, never punishing. A five-problem calibration on first launch means even your first session fits. EIGHT MODES • Add & Subtract — from single digits to four-digit carrying • Multiply — tables through two-by-two digit products • Divide — exact division, then remainders (real mod arithmetic) • Percentages — always exact, never rounded lies • Fractions — add, compare, simplify • Squares & Roots — squares to 25², perfect roots • Powers of 10 — the decimal-shifting reflex • Mixed Gauntlet — everything, blended FIVE WAYS TO TRAIN • Practice — ten adaptive problems, untimed • Sprint — 60, 120, or 180 seconds against the clock • Zen — endless, no score, ambient calm • Gauntlet — twenty problems, three lives, rising difficulty • Daily Challenge — ten problems, date-seeded, the same ten for every Tally user on Earth. Compare your standing when you finish. PROGRESS YOU CAN SEE XP, levels, and ranks from Novice to Grandmaster. A skill graph per mode. Speed trends, your weakest operations detected automatically, and a training heatmap. After every session, a magazine-style review shows each problem, your time, and the mental-math trick you could have used. A STREAK WORTH KEEPING The ember on your home screen grows with your streak — 7, 30, 100, 365 days. Miss a day as a Pro member and a Streak Freeze covers it automatically, two per month. Reminders are gentle, optional, and honest. DESIGNED LIKE IT MATTERS Typography-first interface. A flagship dark mode. Custom haptics on every key.

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.
