I want a clean, intuitive mobile app that can calculate birth-chart data from a user’s date, time, and place of birth, then turn that data into clear horoscope predictions. The heart of the build is the horoscope calculation engine—once the planetary positions are computed, the app must automatically generate day-to-day guidance and short forecasts in a tone I can later edit or expand. Core flow • User enters birth details once and sets notification preferences. • The backend produces real-time horoscope text and pushes it to the device on schedule. • Users can browse past and upcoming readings from a calendar view and share selected predictions. Although daily forecasts are the priority, please structure the code so weekly or monthly snippets can be enabled without rewriting the engine. Tech notes I am open to Flutter, React Native, or native stacks; what matters is a smooth cross-platform release, lightweight database storage for birth data, and secure API endpoints for the ephemeris calculations. Deliverables • Source code with readable comments • Brief setup guide (local build and production deploy) • One round of post-launch bug fixing If you have experience with astrology libraries (Swiss Ephemeris, Moshier, etc.) or have already built horoscope generators, let me know—those examples will help me choose quickly.
