Indian Matrimony App with Horoscope

I need a complete Android and iOS matrimony application tailored for the Indian market. The build must centre on four core modules:

• Rich user profiles and advanced search – each member should enter detailed personal information and upload both photos and videos so they can be found through intuitive filters.
• Real-time communication – text messaging must work instantly, and in-app voice calls should connect members securely without sharing phone numbers.
• Matchmaking and recommendations – an algorithm that suggests compatible profiles based on user-supplied criteria.
• Free horoscope matchmaking – a built-in tool that automatically compares two users’ horoscopes, displaying clear compatibility results at no extra cost.

I expect polished, intuitive native or cross-platform code (Kotlin/Swift/Flutter/React Native are all acceptable) fully tested on the latest Android and iOS versions. Hand-off includes the complete source, build instructions, and store-ready release packages.

Acceptance criteria:
1. Account creation, profile setup, search and filter functions work flawlessly.
2. Text, voice chats connect with low latency under normal 4G conditions.
3. Horoscope comparison produces accurate North & South Indian style charts in under five seconds.
4. No personal data is exposed; all communication paths are encrypted.

Please outline your preferred tech stack and an estimated timeline for each module when you respond.
