About this app

Numina turns daily math practice into an adventure your child actually looks forward to, and it is built, from the very first tap, on the science of how children really learn. WHY NUMINA IS DIFFERENT Most math apps just drill. Numina teaches. Every new idea begins with a short, friendly concept moment before your child answers a single question, because understanding should come first. From there, an adaptive engine quietly tailors every question to your child's level, so they are always challenged but rarely frustrated. BUILT ON REAL LEARNING SCIENCE Numina is designed around principles that decades of education research support: • The number line: children build genuine "number sense" by placing and comparing magnitudes, not just memorising facts. • Teach, then practise: concepts are explained before they are tested. • Interleaving: skills are mixed rather than blocked, which builds flexible, lasting recall. • Spaced retrieval: Numina brings each skill back for review right as it is about to be forgotten. • Adaptive difficulty: the level adjusts continuously to keep every child in their "just-right" zone. • Misconception-aware: when a child slips, Numina spots the pattern and responds with the right nudge. ONE JOURNEY, SIX MATH WORLDS (AGES 8-11) Numina covers the heart of primary-school arithmetic, about grades 3 to 6: • Sparkfield: number sense & first sums • The Tens Foundry: place value & bigger numbers • Array Grove: times tables, multiplication & division • Fraction Peaks: fractions, equivalence & unlike denominators • Decimal Caverns: decimals & comparing • Ratio Reach: integers & percentages MADE TO BE LOVED, NOT ADDICTIVE A children's app should earn trust: • No ads. Ever. • No third-party tracking and no analytics. • No loot boxes, no pay-to-win, no pressure to spend. • Encouraging, mistake-friendly feedback, never punishing. • Private by design, and built to comply with children's-privacy laws like COPPA. THOUGHTFUL EXTRAS • Daily Spark: one fresh, bite-sized challenge to build a gentle daily habit. • A Collection of glowing "spark" friends to discover and grow. • Hand-crafted medals that celebrate real mastery, not just taps. • Daily missions tuned to your child's progress. • A Home-Screen widget, plus iCloud sync across iPhone and iPad. • Optional on-device intelligence adds fresh word-problem variety, processed privately on the device, and easy to switch off. • Works fully offline. FOR GROWN-UPS A parent area (behind a simple gate) lets you see exactly what your child is mastering, set their starting point, and manage settings. No account, no sign-up, no data harvesting. Just clear progress. Numina is for curious kids aged 8 to 11, and for the grown-ups who want screen time to genuinely count.

Latest release

What’s New

Version 1.1.0 Jul 7, 2026

A big update to make practice fairer, fresher, and more rewarding: • Streaks now follow your child's local midnight - after-school practice on back-to-back days always counts. • The Daily Spark now keeps the practice streak alive, and daily progress is never lost. • Leaving mid-session keeps every solved problem, and any medal earned still gets its celebration. • No more seeing the same question twice in a row, plus many new word-problem stories and fraction items for extra variety. • Smarter review: Numina now revisits the skills your child is most at risk of forgetting. • New medals to earn - including a 14-day streak and shiny Supernova milestones - with progress bars showing how close each goal is. • Game Center achievements arrive: First Light, Steady Flame, and Nova Rider. • The Spark now keeps growing past level 6, and a little "Mission complete!" celebration pops up the moment a goal is met. • The home-screen widget now resets correctly at midnight.
