Desarrollo de App movil

Hello, I'm looking to build a mobile app that offers personalized meal and training plans to users (API generated). The app will have two interfaces, one for the user/patient and another for the specialist/professional. The user/patient interface will include features such as account registration, personalized dashboard, and access to generated meal and training plans. The specialist/professional interface will include features such as account registration, personalized dashboard, and access to patient information, generate and approve meal and training plans for patients, and a chat feature to communicate . In terms of design, we'll need approximately 25 screens for both interfaces: For the user or patient interface: Sign Up Screen Login Screen User information screen (Personal, Health Objectives, Eating Habits, Physical Activity Habits, Progress History) Meal plan selection screen - Subscription Model Training plan selection screen - Subscription Model User progress tracking screen FAQ screen. Online chat screen for questions and inquiries. Eating and Excercise tracking screen. Generated, current, and previous plan screen. Community (Posible) For the professional interface: Login screen. Professional registration screen. List of clients and plans screen. Client personal information screen. Client plan approval screen. Meal and training plan templates screen. Tools to customize plans screen. Client progress tracking screen. FAQ screen. Community (Posible) We need this done from scratch. We only have the concept and logo. React Native would be best, Flutter is also an option. Open to suggestions. Need it for IOS and Android If this project is of interest to you, please let us know and we can discuss it further.
