Mobile Car Wash Booking App

I’m looking for a clean, user-friendly mobile application that lets my customers book car-wash appointments directly from their phones. The heart of the project is a solid booking system that supports both single appointments and, most importantly for me, recurring services. Customers should be able to choose a preferred date, time, and location, then set the service to repeat at an interval I can configure from the back end.

The flow needs to feel effortless: account creation with basic profile details, a calendar-style scheduler, push notifications or SMS reminders, and a quick view of upcoming washes. On my side I need an admin panel (web or in-app) where I can adjust available time slots, manage incoming bookings, and see at a glance how many recurring services are active.

Please build the solution for both iOS and Android; whether you choose Flutter, React Native, or native stacks is up to you as long as performance is smooth and the UI matches modern design standards. REST or GraphQL APIs are fine, and Firebase, AWS, or an equivalent for authentication and real-time data will work—just outline your choice in your proposal.

Deliverables:
• Fully functional iOS & Android apps packaged for release
• Admin dashboard for schedule and user management
• Source code with clear instructions for future interval changes
• Brief hand-over session and basic documentation

A straightforward, dependable build is my priority, so if you’ve created booking or scheduling apps before, I’d love to see them when you bid.
