Mobile App Developer for MVP

Mobile App Developer (Flutter / React Native) – MVP Workout & Progress Tracking App Summary Looking for a talented mobile developer to build a lightweight, cross-platform workout application (iOS & Android) that allows clients and athletes to access, follow, and track structured fitness programs. We initially considered a Notion-based build but have decided to pivot to a native cross-platform MVP to ensure a seamless, reliable user experience in low-connectivity gym environments, proper database scalability, and absolute ownership over our data and user management. The project includes a clean, consumer-facing mobile app and a simple admin panel/backend for program management. Scope of Work 1. Front-End Mobile Experience (iOS & Android) Framework: Built using Flutter or React Native to ensure a single, highly performant codebase. User Interface: Clean, intuitive, and modern UI designed specifically for quick, in-gym interactions (large buttons, minimal clutter). Workout Views: Display structured training plans organized by daily, weekly, and block views. Tracking & Progression: Enable users to easily log completed sets/reps/runs, check off completed workouts, and view basic progress history. Offline Support: Basic local caching so athletes can view and log workouts even with spotty gym Wi-Fi/cellular data. 2. Back-End & Database Setup Infrastructure: Lightweight, scalable backend (e.g., Supabase or Firebase). Content Management (Admin Panel): A simple dashboard or admin portal where I can easily create, update, and manage workout programs without writing code. User Authentication: Secure signup/login for clients and athletes. 3. Program Architecture & Scalability I will provide 3–5 initial workout programs (Running, Strength/Lifting, and Hybrid Training). The developer must: Build a flexible, repeatable database schema so new programs, exercises, and progressions can be added seamlessly via the admin panel. Organize workouts and metrics in a standardized, clean format. 4. Training & Handoff Upon completion, the freelancer will: Provide a walkthrough of the admin panel and system architecture. Document the process for adding/updating workout programs. Ensure clean, commented code for future feature expansions. Ideal Qualifications Mobile Development: Proven experience building and deploying cross-platform apps using React Native or Flutter. Backend & DB: Experience with Supabase, Firebase, or similar lightweight backend solutions. Fitness UX Experience: A strong understanding of fitness programming, workout tracking, or sports performance workflows is a massive plus. MVP Mindset: Ability to balance clean code with speed-to-market, focusing on a robust core experience without over-engineering. To Apply Please share: Examples of mobile apps you have built (specifically any involving tracking, data inputs, or client portals). Your preference between React Native and Flutter for this specific use case and why. A rough estimate of timeline and budget for an MVP of this scope.
