I’m building a cross-platform appointment system that runs natively on both iOS and Android. At its core, the app lets barbers, nail technicians, beauty salons, spas and similar businesses create their own branded space within the application, then accept an unlimited number of bookings from their clients. Here’s what I need engineered: • Two distinct user flows: a secure account area for business owners, and a friction-free booking experience for their end-clients. • Inside the owner dashboard each business must be able to upload full business details and logo, add a banner photo, and publish product or service pricing so clients can choose exactly what they want before confirming an appointment. • Subscription handling: owners subscribe in-app, then enjoy unlimited bookings; the payment layer must support simple plan setup, recurring charges and automated renewals. • Calendar sync: every confirmed slot should push instantly to the owner’s Google Calendar (two-way sync preferred so changes made in Google reflect back in the app). • Reliable real-time notifications to both parties on creation, reschedule or cancellation. • Scalable database architecture so there is no hard limit on the number of participating businesses or appointments. If you’ve previously delivered polished Flutter, React Native or native Swift/Kotlin scheduling solutions, I’d like to see them. Quality, clean code and an intuitive UI are more important to me than fancy animations, but the app should still feel modern and brandable for each business owner.

Hi, there. I have carefully reviewed the requirements for Multi-Salon Appointment Booking App. Based on your goals, you are looking for a mobile experience that is not just functional, but seamless and responsive for your users. My team and I specialize in mobile app engineering with a focus on high-performance architecture. We have a proven track record of helping businesses in United States build mobile solutions that scale effectively across both iOS and Android. Whether we are leveraging Website Design, React Native, Android, iOS Development, Mobile App Development for a native build or a cross-platform solution, our focus is on ensuring the interface is intuitive and the backend data handling is secure. We treat every app we build as a long-term asset. We avoid common pitfalls in mobile development such as memory leaks or poor UI responsiveness, ensuring your users have a smooth experience from their very first interaction. To help me provide a precise timeline for your development, I have one quick question: Are you aiming to launch on both platforms simultaneously, or are you prioritizing one (iOS or Android) for your initial market validation? Knowing this helps me determine the most efficient architectural path for your project. I am available for a discovery call to discuss your mobile roadmap whenever you are ready. Best regards Kausar and the Team

Hi there, This is something I have worked on before. I can help you build a scalable appointment booking platform where businesses manage their own branded profiles while customers enjoy a smooth booking experience. What I will do is first build the two user flows—one for business owners with profile, pricing, subscriptions, and calendar management, and another for customers to browse services and book appointments effortlessly. Then I will integrate recurring subscription payments, Google Calendar synchronization, real-time notifications, and a scalable backend that supports unlimited businesses and bookings. After that, I'll optimize the app for both iOS and Android, ensuring it remains fast, intuitive, and easy to extend with future features. I have a few questions: Which subscription gateway would you prefer (Stripe, RevenueCat, Apple/Google In-App Purchases)? Should customers be able to book as guests, or is account creation mandatory? I would recommend Flutter with Firebase and Stripe as it provides a single codebase, real-time sync, push notifications, and excellent scalability. I would request to connect once so we can discuss the workflow in detail and finalize the development roadmap, timeline, and budget. Thanks, Rahul A.

Hi, I can see the real pressure here: you need one app that feels simple for clients, yet powerful enough for multiple businesses to run bookings, subscriptions, calendars, and notifications without chaos. That balance is exactly where I can help. I’ve built web and app systems with booking flows, payment subscriptions, dashboard logic, and API integrations, so I can structure this cleanly for scalable use across salons, barbers, spas, and similar businesses. I’ll focus on the owner area, client booking flow, Google Calendar sync, recurring subscription setup, and a database design that can grow without hitting limits. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If you’d like, I can outline the best approach for Flutter or React Native, plus the backend structure for bookings, payments, and sync. Do you want each business to manage its own separate calendar and subscription plan, or should there also be a platform-level admin panel for oversight? Best regards, Asad Looking forward to your reply so we can finalize the exact plan.
