AI Astrology App Like AstroTalk

I’m planning to launch a mobile astrology platform powered by AI, inspired by the overall user experience of AstroTalk. My immediate goal is a polished, production-ready app for both iOS and Android that can scale as our user base grows.

Core scope
• End-to-end development of a native or cross-platform app (I’m open to React Native, Flutter, Swift/Kotlin, or another proven stack you recommend).
• AI layer that generates astrological insights—how you structure the models, prompts, or external APIs is up to you, but accuracy, speed, and privacy are critical.
• Real-time live chat module where users can connect with human astrologers; include a queue system and basic moderation tools.
• Push-notification system for timely updates (daily readings, promotion alerts, chat reminders, etc.).
• In-app purchases so users can buy credits, premium readings, or subscription tiers. Apple Pay and Google Play billing must be integrated cleanly.

Key deliverables
1. iOS and Android builds, fully tested and deployable to App Store & Google Play.
2. Secure backend (Node.js, Django, Firebase, or similar) with user auth, chat routing, payment tracking, and an admin dashboard for managing astrologers and content.
3. Clean, maintainable source code in a private repo, plus brief technical documentation and hand-off call.

Acceptance criteria
• Smooth onboarding flow and modern UI/UX.
• AI responses return in under three seconds on a 4G connection.
• Live chat remains stable for sessions of 30 minutes or more.
• Push notifications reach 95 % of test devices.
• All in-app purchases pass Apple & Google review without issue.

If you have prior experience with AI-driven content, real-time chat, or fintech-grade payment flows, let me know. Please outline your proposed tech stack, timeline, and any similar apps you’ve shipped so I can gauge fit quickly.
