AI-Powered Gym Coaching App. React, TypeScript, Supabase, Claude AI Integration

Project Overview I am seeking a build cost estimate for a custom AI-powered gym coaching web application. This is a quote request — I am assessing the market cost to build this app from scratch and am not necessarily looking to hire immediately. Please provide your honest fixed-price estimate based on the scope below. What the App Does A web application used by gym coaches and managers to generate personalized 8-week training programs for clients. The app uses a custom slot-filling algorithm to build programs based on each client's profile, then passes the result to the Claude AI API for a quality review. Coaches can view, manage, and track all client programs through a dashboard. Core Features - Client management (profiles, training history, restrictions, goals) - AI-powered program generation — custom algorithm assigns exercises to slots based on movement patterns, client level, restrictions, equipment availability, and training style - 6 training style templates (sequential, superset, movement pattern split, etc.) - 437 exercises stored in a database with tags for movement pattern, laterality, mechanics, level, goal, and equipment - 8-week program viewer with session logging - AI quality review of each generated program (Claude API integration — 3 API calls per program) - Multi-role access (coach and manager roles) - Manager dashboard with usage metrics - Offline support with sync queue - Mobile-ready PWA (installable on iOS and Android) Tech Stack - Frontend: React, TypeScript, Vite, TanStack Router, Tailwind CSS, shadcn/ui - Backend/Database: Supabase (PostgreSQL, auth, real-time) - AI: Anthropic Claude API - Hosting: Lovable / Vercel-compatible Scale - ~600 clients across 2 gym locations - ~280 programs generated per month What I Need From You Please provide: 1. Your fixed-price estimate to build this app from scratch to production 2. Estimated timeline to complete 3. Your relevant experience with similar projects Note: The program generation algorithm is the most complex part of this build. Please factor this into your estimate, it is not a standard CRUD feature.
