In one line
Numina is a daily math puzzle: five problems a day, the same five for everyone, with a spoiler-free result you can share.
The story
Word games found their daily ritual years ago: one puzzle, everyone on the same footing, a grid of squares that tells your friends how it went without spoiling it. Math never got one. The usual brain-training apps push timers, guilt and ads, and mark "37.5" wrong because you didn't type "37.50".
Numina is built the other way round. Each morning brings Today's Math — five problems generated the same for every player on Earth, with a day number. Your first attempt is the one that counts; replays are practice. When you finish, you share a row of dots, not the answers, and a friend who taps your link lands on that exact day's five.
Around that daily ritual sits a calm, adaptive trainer drawn as a night sky. Seven constellations track seven ways of thinking, from number flow to working memory, and every problem you solve lights a star. Numina retunes after every answer so practice always sits where thinking feels good. Deep Sky lets you talk through riddles and estimation puzzles with a guide that runs entirely on the device, using Apple Intelligence where available. The game's own engine checks every answer — a language model is never allowed to decide what is correct.
There are no accounts and no servers of ours. Progress stays on the device, or, if the player chooses, in their own iCloud.
What makes it different
- Nearby Duel. Race a friend live, phone to phone: tap their orb, a countdown starts on both phones at once, and the first right answer takes each star. Standard, First to 5, and an Equalizer mode that lets a parent and child race fairly. Nearby duels need no internet and no servers; online duels use Game Center. Hosting is part of Numina Complete, and guests play free.
- A fair daily. Same five for everyone, first try ranked, hints and replays labelled, day identity independent of time zones — and a versioned generator so an update never changes a past day.
- Math you can trust. Every answer is graded by arithmetic, not guessed by a model; units, fractions and decimals are read the way you meant them.
- On every screen you glance at. Answer from the Lock Screen without unlocking, or climb on Apple Watch.
- Made for iPhone Duo. Folded, it fits the cover with controls in the side strip; opened, each screen splits at the fold so nothing you tap sits on the crease.
- Built for everyone. VoiceOver throughout, Dynamic Type at every size, Reduce Motion and Low Power respected, and an Echoes memory mode that waits for screen-reader users instead of racing them.
- Private by design. Data Not Collected on the App Store privacy label.
