I need a single system that lets our childcare staff book children in and out each day, while keeping every child’s profile—including allergy or medical notes—instantly available. The solution must work in a browser for office staff and as a mobile app for iOS and Android so educators and parents can interact on-site or on the go. Core flow • Staff (or parents, if you prefer) scan, tap, or otherwise confirm a child’s arrival and departure. • The action time-stamps automatically and updates occupancy numbers in real time. • Opening any child’s record shows allergies, dietary needs, emergency contacts, and any custom notes without extra clicks. Key features I expect from the first release – Secure child check-in / check-out with clear audit history – Central allergy & medical database searchable by name or classroom – Optional parental access so families can view or confirm their own child’s status Please propose the stack you recommend, outline major milestones, and share one or two past projects where you built something similar (a demo link or short video is perfect). I’m happy to discuss UI mock-ups, data fields, and rollout logistics after we’ve confirmed feasibility and timeline.
