I need a mobile app that lets customers book our services quickly and drives measurable sales growth. The core idea is a streamlined service-booking flow, not a full e-commerce catalog. Key features I want built: • Account creation with social or email sign-up • Service catalogue with real-time availability and pricing • Calendar picker for users to choose appointment slots • In-app payments (credit card, Apple Pay, Google Pay) • Push notifications for confirmations, reminders, and promos • Admin dashboard where my team can add or edit services, prices, and time slots For the first release, I’m looking for: 1. Wireframes and polished UI mock-ups that match our brand colors. 2. A working iOS and Android build using React Native or Flutter—whichever you are most comfortable with—connected to a lightweight backend (Firebase, Supabase, or a similarly scalable option). 3. Basic analytics hooks so I can track bookings, revenue, and funnel drop-offs. Code must be well-documented and handed over via Git. Once the MVP is accepted, I’m open to a follow-on contract for feature iterations and maintenance, so please structure the project so future updates are straightforward. If you have launched a service-booking app before, share a link or screenshots so I can see your approach.
