I’m ready to build a unified platform that covers every side of the wedding-planning journey—one seamless experience for both engaged couples and professional planners, delivered as a responsive web app plus companion Android and iOS apps. What the product must do Couples will log in to shape their big day with an interactive checklist & timeline, track RSVPs through a live guest-list manager, and keep budgets under control in one dashboard. Planners, on the same system, will oversee vendor details, chat with clients in real time, and schedule every event milestone without hopping between tools. Core deliverables • Web application (desktop & mobile responsive) • Native or cross-platform Android and iOS apps that mirror web functionality • Shared database and secure user authentication so couples and planners can collaborate but keep their data partitioned • Admin panel for my team to manage user roles, vendors, and content • Clean, modern UI/UX that feels effortless for non-tech users Acceptance criteria 1. All six feature sets—Checklist & Timeline, Guest List Management, Budget Tracking, Vendor Management, Client Communication Tools, Event Scheduling—function smoothly on web, Android, and iOS. 2. Real-time sync: an update on one device appears on the others within seconds. 3. Role-based access controls prevent couples from seeing planner-only tools and vice versa. 4. Deployed to production hosting and both app stores with clear documentation for future updates. If you have a proven track record delivering multi-platform apps—whether you prefer React + React Native, Flutter, or a similar modern stack—let’s talk timelines and a milestone breakdown to get this live well before the next wedding season.
