Astrology Live Consultation App

I need a complete mobile application, modelled on Astroyogi’s core flow, where users can book and enjoy real-time consultations with professional astrologers. The goal is to give a smooth, engaging experience on both iOS and Android.

Key points I already know I want:
• Focus on live, one-to-one consultations (voice, video and in-app chat are all acceptable solutions—let me know which you recommend and why).
• A clean dashboard for users to browse available astrologers, view ratings, and start a session instantly or schedule one.
• Secure payment handling so I can charge per minute or per session.
• Simple, reliable sign-up options (email, phone, Google/Apple).

Please include in your proposal:
1. The tech stack you’d use for a dual-platform launch, plus any backend or admin panel needs you foresee.
2. A realistic development timeline with your milestone breakdown.
3. An overall cost estimate and any licensing or third-party fees I should be aware of.
4. Post-launch support or maintenance you can provide.

If you have built similar marketplace or consultation apps before, links or store references will help me judge fit quickly. I’m ready to move forward as soon as I see a clear plan on time and budget.
