AstroCalcul
Learn math by exploring the Solar System. Ad-free & Privacy
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.

Hi Product Hunt community! 👋 I’m Jeremy, an indie developer from Belgium and a proud dad. This project started at my desk when I saw my daughter struggling with her math tables. All the apps we tried were either too boring or filled with distracting banners. I wanted something that felt like a journey, not a chore. AstroCalcul is the result of my late-night coding sessions. It’s a gift to her and to all parents who want a clean, safe, and beautiful educational experience for their kids. Right now, it's live on iOS, and I’m currently working on the Android version (on my Pixel 9!) to make it available for everyone. I’d love to hear your feedback or answer any questions about the tech stack (SwiftUI/Kotlin) or the educational approach. Thanks for supporting an indie maker!
