My car-washing center needs a clean, user-friendly mobile app that lets customers choose an available date and time, then lock in their wash slot. I want the same experience on both iOS and Android, so a shared code-base approach such as Flutter, React Native, or another cross-platform framework is welcome as long as performance feels native. Booking logic • Customers must be able to make either a one-off appointment or set up a recurring slot (for example, every Friday at 10 a.m.). • Once a slot is confirmed, the user receives an automatic SMS confirmation that includes the appointment details and a cancellation link. • The system should block double-booking and clearly show which times are already taken. Admin view I need an internal screen or lightweight web dashboard where my staff can: – Add, edit, or cancel appointments manually – Set working hours and holiday closures – View daily, weekly, and monthly calendars at a glance Data & integrations The SMS confirmations can run through Twilio or another reliable gateway; whichever you prefer, just note any extra fees in your proposal. Please plan for secure user data storage and a simple login system—email + OTP or a quick social sign-in is fine. Acceptance criteria 1. Test builds run smoothly on recent iOS and Android devices. 2. Single and recurring bookings work without conflicts. 3. SMS confirmation reaches a real phone during demo. 4. Admin dashboard updates reflect instantly in the customer app. Source code, build instructions, and any third-party license details must be handed over at project completion. Feel free to suggest UI improvements or additional quality-of-life features if they fit naturally into the workflow.

Hello, I can build a polished, cross-platform booking app that makes scheduling a car wash effortless for customers and simple to manage for your staff. The real pain points I see: double-bookings during peak times, clumsy recurring-slot UX, slow admin workflows for manual changes, and unreliable confirmation messaging. I’ll fix all of that with a tight, tested implementation. What I’ll deliver: • Cross-platform app (Flutter) with native-feeling performance on iOS & Android. • Booking engine that supports single & recurring appointments, enforces working hours/holidays, and blocks double-bookings with server-side availability checks and optimistic UI. • Lightweight web admin dashboard (React) for adding/editing/cancelling slots, setting hours/closures, and calendar views (day/week/month) that update instantly via realtime (WebSocket) or server-sent events. Acceptance-ready: test builds on devices, recurring & single bookings without conflicts, SMS demo to a real phone, and instant admin/app sync. I can start immediately and propose a 1-2 week MVP delivery with weekly checkpoints. Ready to get this live. Regards Avinash

I am Sumit Joshi from Sacesta Technologies. I can build your car-wash booking app as a single codebase for iOS and Android with smooth, native-feeling performance. I’d suggest Flutter so we get fast UI, easy calendar views, and reliable store releases. The app will let customers pick a date and time, choose one-off or recurring bookings (for example, every Friday 10 a.m.), and clearly see which slots are already taken. A simple login (email + OTP, with option to add social later) will keep data secure and let users view or cancel their own appointments. For notifications, I will integrate Twilio (or a similar gateway) so every confirmed booking triggers an SMS with date, time, location, and a unique cancellation link. Gateway usage is billed per SMS by the provider; I will document expected fees based on your target countries before we lock it in. You’ll also get an internal admin dashboard (web or in-app) where staff can set working hours and holidays, add or modify bookings, and see daily, weekly, and monthly calendars in real time. All changes will sync instantly to the customer app, with double-booking prevented at the data level. I will deliver clean, documented source code, build instructions, and a short handover guide, plus test builds so we can verify bookings, recurring logic, SMS delivery, and admin features on real devices. Regards, Sumit Joshi
