I need a full-stack iOS application DESIGN and VISUAL LAYOUT that lets freelance beauty professionals handle every step of their business from a single place. The core flow is simple: a client books, the appointment lands instantly in the stylist’s schedule, a smart contract is generated, and expenses are logged in the background—-all without leaving the app. Key elements I expect: • iOS-native front end built with a modern stack (SwiftUI preferred) connected to a secure, scalable back end. • Seamless Google Calendar integration—when a slot is taken or changed, both calendars stay perfectly in sync. • ChatGPT embedded throughout the workflow to draft service agreements on the fly, answer client FAQs, auto-categorize expenses, and surface insights. • A lightweight data and expense module so artists can snap a receipt or enter a figure and have it stored, categorized, and ready for export. • Intuitive admin screens for rates, availability, client notes, and contract templates. At launch I only need Calendar integration, but the architecture should leave room for Automated reminders and Payment processing down the line. Acceptance will be based on a test build that: 1. Installs on current iOS devices. 2. Creates, updates, and deletes bookings while mirroring changes in Google Calendar within seconds. 3. Generates a contract draft via ChatGPT using the appointment details. 4. Records a sample expense and saves it to the user’s data store. 5. Demonstrates clean, documented code and secure handling of user data. If you can deliver a smooth, intuitive experience that blends solid mobile engineering with practical AI, we’re set to move forward.
