Hey everyone!
I’m excited to share that AstroAlert, my astronomy app built entirely with FlutterFlow, is now officially live on the App Store!
AstroAlert turns your phone into a personal space control center.
It calculates which satellites, planets, and deep-sky objects will pass right above your location in the next 24 hours — using real orbital data (TLE, NASA Horizons, JPL ephemerides).
Key Features
• Satellite pass tracking with NASA-grade accuracy
• Planets, Moon, Sun, and selected comets
• Only shows spectacular, high-altitude events (70°+)
• Deep-sky objects (nebulae, supernova remnants, bright stars)
• Alerts for “impossible to miss” events (80°+)
• NASA Photo of the Day
• In-app astronomy glossary
• Designed with a mission-control inspired UI
I built the entire app with FlutterFlow, including:
• Firebase integration
• Recurring background processes
• Custom functions for orbital calculations
• A premium tier with subscriptions
• A fully custom dark sci-fi UI
Now available on iOS:

(Android version coming soon — currently in closed testing.)
If you want to check it out or have any feedback, I’d love to hear it!
And of course, huge thanks to the FlutterFlow team and this community for all the inspiration along the way 🙌
Clear skies! 🌌
