I’m building a mobile experience that delivers one-of-a-kind natal chart readings. The app’s entire focus is on accuracy and a smooth, engaging user journey. Core flow • The user supplies three items: date & exact time of birth, place of birth, and name / gender. • The back-end computes a complete natal chart (planets, houses, aspects) with ephemeris-grade precision. • The front-end presents an intuitive, visually rich interpretation written in everyday language. What I need from you – A cross-platform build (Flutter or React Native are welcome; native Swift / Kotlin is also fine) that runs on both iOS and Android. – Integration of a proven astrology library such as Swiss Ephemeris, AstroPy, or a comparable engine to guarantee calculation accuracy. – Secure profile management that lets users store multiple charts on a single device. – A clean onboarding flow, dashboard, and shareable highlights. – Hooks for future in-app purchases so premium, deeper readings can be unlocked later. Deliverables 1. Complete source code with build instructions 2. Two store-ready binaries (App Store & Google Play) 3. Lightweight admin tool or script for updating interpretation text 4. Documentation covering architecture, libraries, and maintenance steps Acceptance criteria • Entering verified test data returns a chart matching industry-standard software within one arc-minute. • The app installs and functions on current iOS and Android versions without crashes. • UI passes basic accessibility checks and loads in under three seconds on mid-range devices. If you have a clear approach to the calculation engine and a solid eye for user-centric design, I’d love to work together.
