AstroCalcul

什麼是 AstroCalcul？

I built AstroCalcul because I couldn't find a math app for my 7-year-old daughter that wasn't a "slot machine" of ads and subscriptions. AstroCalcul turns math drills into a space odyssey. Instead of boring lists, children explore a 3D-style solar system where every multiplication or division unlocks real facts about planets. Key features: Privacy-First: No ads, no trackers, no data collection. Educational Depth: Learn astronomy and math simultaneously.
