Hair Salon Appointment Management App

I'm looking for a cross-platform (iOS & Android) application designed for a hair salon. The primary functions of this app should include online booking and a section for customer reviews.

Key Features:
- Online Booking: Customers should be able to book appointments seamlessly through the app.
Reminder: app should remind their turn
- Customer Reviews: There should be an interface where customers can leave reviews after their appointments.

User Authentication:
- The app will require a user authentication system, but this will only be for customers. Staff will not need to create accounts.

Ideal Skills:
- Cross-platform App Development
- UI/UX Design
- Backend Development for User Authentication
- Experience with Online Booking Systems
- Knowledge of Implementing Customer Review Features
