Astrology Horoscope Prediction App

I want a mobile application that centres on horoscope calculation and prediction. The user should enter their birth date, exact time, and location; the app must instantly compute the chart and present accurate daily horoscopes. On top of that core flow, I need personalised predictions that push timely insights to each user based on their unique data.

A friendly, modern interface is essential, but the mathematical engine behind it has to be solid—please rely on a proven ephemeris library such as Swiss-Ephemeris, NASA JPL data, or an equivalent you already trust. Native iOS and Android builds are welcome, though a high-performance cross-platform framework like Flutter or React Native is perfectly fine if it keeps the experience smooth.

For future-proofing, the code should be clean, well-commented, and handed over with basic documentation. Privacy matters to my audience, so local-first storage with optional cloud sync would be ideal, and GDPR-compliant analytics only.

Acceptance criteria:
• Users receive accurate daily horoscopes and personalised predictions after submitting birth details
• Calculation engine passes spot checks against at least three reference charts I will provide
• Push notifications deliver predictions reliably on both iOS and Android
• Source code, build instructions, and graphic assets are supplied in a well-organised repository

Once these points are met, the project is complete and ready for App Store and Play Store submission.
