Customer Booking Mobile App

I want to bring a new mobile app to life that lets our customers browse, select and complete a purchase or booking in just a few taps. The core goal is clear: make it effortless for users to move from discovery to checkout, whether they’re paying for a product, securing a service slot, or reserving tickets and rentals.

Here’s what I need from you:
• A clean, intuitive front-end for iOS and Android (React Native or Flutter are both fine—use whichever you’re strongest in).
• A secure back-end that handles account creation, item listings, real-time availability, cart management and payment processing. Stripe or a comparable gateway works, provided it supports card payments and popular e-wallets.
• Admin tools so my team can add new offerings, adjust prices, set inventory or time slots, and view basic sales reports.
• Push notifications and email confirmations that trigger on order status changes.
• Basic analytics hooks so we can track installs, conversions and retention.

Acceptance criteria
1. Users can register, browse the catalogue, add to cart, and complete a payment without errors.
2. Admin panel updates sync to the app in real time.
3. All sensitive data is transmitted via HTTPS and stored securely.
4. App passes TestFlight / Play Console review and is ready for public release.

If you’ve launched similar buy-or-book apps before, show me links or screenshots along with a brief note on the tech stack you used. I’m ready to move quickly once I see a fit.
