The Coach AI – Cross-Platform AI Coaching Application

Problem

In the growing world of personal development and digital coaching, users demand a simple, intuitive way to engage with AI-powered life and business coaches. The challenge for The Coach AI team was to create a cross-platform application that delivers a consistent, seamless coaching experience across web, iOS, and Android – all while maintaining subscription-based access control and legal compliance.
They needed a scalable MVP that looked and felt production-ready but could later be enhanced with full AI logic. The system had to integrate FlutterFlow for UI/UX, Firebase for real-time data, and RevenueCat for managing global subscriptions ensuring users can chat, subscribe, and interact securely, with backend intelligence ready to grow.

Key Challenges

• Cross-platform consistency: The design and UX had to perform flawlessly on web, iPhone, and Android devices.
• AI-ready backend: The system needed stubbed coaching logic for now, but flexible enough for future GPT-based enhancements.
• Secure data management: User profiles, conversations, and subscription states had to be stored safely and synced in real-time.
• Subscription logic: Needed automated blocking/unblocking of access depending on subscription status.
• Legal compliance: Users must review and accept Terms of Service before any AI session.

Solution

BytezTech delivered The Coach AI as a production-ready cross-platform MVP that blends elegant UI, strong architecture, and monetization readiness. Built in FlutterFlow, powered by Firebase Functions, and monetized with RevenueCat, the solution sets the foundation for a scalable AI coaching platform adaptable to multiple languages and markets.

Cross-Platform App with FlutterFlow

• Designed and developed the app strictly following the provided Figma prototype under Material Design principles.
• Ensured responsive, platform-specific UI optimization for Web, iOS, and Android.
• Incorporated modular widgets for scalable updates without redesigning layouts.
• Maintained a single codebase that outputs production-ready builds across all platforms.

AI-Ready Firebase Cloud Stubbed Logic

• Implemented Firebase Cloud Functions for the two main flows: CreateConversation & SendMessage
• Stubbed both APIs with mock responses for seamless frontend integration.
• Architected the backend to allow future integration of OpenAI or Vertex AI models without rewriting app logic.

Subscription & Monetization with RevenueCat

• Integrated RevenueCat to handle all operations: Subscribe, cancel, or modify payment methods
• Built Firestore and Firebase Functions logic to check active subscription status dynamically.
• Configured automatic session blocking/unblocking for free vs. premium users.
• Ensured real-time synchronization between RevenueCat and Firestore for reliable payment validation.

Legal & Data Management with Firestore

• Integrated Terms of Service directly into the app, reflecting the content from the official the-coach.ai/terms-of-service.
• Enforce mandatory user consent before initiating any coaching session.
• Established Firestore schemas for users, conversations, and subscriptions with strong access control rules.
• Implemented Firebase Security Rules to ensure that only authorized users can access or update data based on subscription level.

Result

BytezTech successfully launched a production-ready MVP of The Coach AI, now live across Web, iOS, and Android, providing users with a unified, secure, and visually consistent coaching experience. The app not only meets all functional acceptance criteria but is fully prepared for rapid AI enhancement and global scaling.
