Multi-Gym Fitness App MVP

@Microlent

Your posting caught my attention. Multi-tenant fitness apps fail if data isolation isn’t enforced at the DB + API level, so that’s the core focus here. Approach: Flutter (fast Android-first + clean UI) Backend: Node.js + PostgreSQL Multi-tenant design: every record tagged with gym_id + enforced at API layer Core build: Admin: members, workout/diet plans, progress tracking User: workout logging, diet input, progress + charts 4-tab clean UI (Dashboard, Workout, Diet, Progress) Security (important): Gym-level isolation via JWT + gym_id scoping Queries always filtered by gym_id (no cross-access possible) Role-based access (admin vs member) Timeline (tight but doable): Day 1–2: Setup + auth + DB Day 3–6: Core features Day 7–9: UI + testing Day 10: Final build + walkthrough Deliverables: APK + full source Setup docs + onboarding flow for new gyms For similar work: https://www.freelancer.com/u/Microlent — Rajesh Rolen

Hi, I can build your Android-first multi-gym fitness app with a clean, scalable architecture and strict tenant isolation. With 10+ years of experience in mobile and backend development (Kotlin, Node.js, React Native), I’ve built apps with role-based access, dashboards, and real-time tracking systems. Proposed stack: • Android: Kotlin (for performance and clean native UI) • Backend: Node.js (Express/NestJS) • Database: PostgreSQL (with strict tenant-based schema design) Tenant isolation: Every record (users, workouts, diet, progress) will be linked with a unique gym_id. Middleware-level validation will ensure users can only access data within their gym. Role-based access (admin/user) + JWT authentication will enforce security at API level. Features covered: • Admin: member management, workout/diet plans, progress tracking • User: workout logging, nutrition tracking, body stats, charts • Clean 4-tab UI: Dashboard, Workout, Diet, Progress Timeline: 8–10 days for MVP Milestones: • Day 1–2: Setup + auth + structure • Day 3–6: Core features • Day 7–9: Testing + polish • Day 10: Delivery + walkthrough I can share similar fitness/dashboard app work on request. Ready to start immediately. Best regards.

Hi there, I have read your project requirement. You need an Android-first multi-tenant fitness app with secure gym-wise data separation, admin and user features, and a clean 4-tab interface. We will build a scalable app using Flutter with a secure backend (Node.js + PostgreSQL). The system will support multiple gyms with strict data isolation, admin features (member management, workout/diet plans, progress tracking), and user features (workout logging, diet tracking, measurements, charts). The app will be clean, fast, and ready for future expansion. Questions: ========== Do you need a web admin panel or only mobile admin? Should progress images be stored locally or on cloud? Any preferred UI style/reference for the app? Will subscription/payment features be needed later? Best Regards, Srashtasoft Team

With over a decade in the industry, I'm confident that I have the skills and experience necessary to bring your Multi-Gym Fitness App MVP to life. In my extensive career, I’ve successfully completed more than 100 projects, including several fitness apps and multi-tenant systems that are currently being used by various clients. One such example is "FitnessPro", a similar platform allowing multiple trainers and clients to interact seamlessly while keeping their private data completely separated – just like your requirement. For this project, I recommend using a combination of Kotlin for the Android build and Laravel for the backend server. Laravel provides excellent security measures and makes it easy to implement the multi-tenant architecture you desire. Not only will your app be sleek and professional-looking, but the codebase itself will be clean and extendable - ready for further development down the line. I understand your need for quick turnaround times. Rest assured, I won’t sacrifice quality for speed. My proposed budget is competitive without compromising any technical capabilities. As a long-term partner, I will always provide prompt support post-deployment. Let's get started on bringing this wonderful app to life together!

As a seasoned full-stack developer with over 5 years of experience, I have successfully created and deployed more than 30 mobile applications – including some that align closely with your vision. For example, the Victoria UAE Real Estate app, which you can check out on both the App Store and Google Play. I believe my background in crafting sleek and professional user interfaces, using both Flutter and React Native would be a tremendous asset for your multi-gym fitness app. In terms of technology, your project leans towards native platforms more than any others. Therefore, I'd strongly recommend we go with Kotlin for the Android build to ensure superior performance and smooth scalability. To guarantee tenant isolation and data security, we'll utilize Firebase as a backend solution, which is not only secure but also pretty efficient and flexible. Additionally, I have great experience leveraging clean codebases to ensure easy navigation and understanding for future development stages.

I have read your job post and I can build your Android-first multi-gym fitness app MVP with a clean, scalable architecture. I am a mobile developer with experience in Flutter, Kotlin, and backend systems that require strict data isolation and role-based access. For this project, I recommend using Flutter for the Android app because it allows fast development, clean UI, and easy future expansion to iOS if needed. For the backend, I would use Node.js or Firebase with a properly structured multi-tenant database where every record is strictly linked to a gym ID, ensuring complete data separation between gyms. Authentication can be handled via phone or email login using secure token-based sessions. To guarantee tenant isolation, all API requests will be scoped by gym ID, enforced at both backend middleware and database query level, so no gym can access another gym’s data even accidentally. I will also structure the codebase in a modular way so new gyms can be created instantly through the admin system.

@abhishek060

Hello Yes — I’ve built similar multi-tenant fitness systems where each gym’s data is fully isolated under one platform. I understand your key requirement clearly: each gym must operate independently with zero data overlap, while sharing the same app infrastructure. I’d build this using: • Flutter (Android-first, scalable to iOS) • Node.js (NestJS) backend • PostgreSQL with strict gym-level data isolation Tenant isolation would be enforced at: • database level (gym_id scoping) • API middleware access control • role-based permissions (owner / trainer / member) MVP plan (10 days) • Day 1–2: Architecture + auth + gym setup • Day 3–5: Admin panel (members, workouts, diet plans) • Day 6–8: User app (logging + progress tracking) • Day 9–10: Charts, testing, APK + handover I can start by locking the architecture + data model first so you can validate multi-gym isolation before development begins. If needed, I can also share a similar fitness system structure I’ve implemented. Regards, Abhishek

@aravinthv7

Hi, I can build this Multi-Gym Fitness MVP as a clean, scalable multi-tenant system. Tech Stack: Flutter + Firebase (fast development, secure real-time database, easy scaling). Similar experience: I’ve built fitness/workout tracking apps with admin-user roles, progress tracking, and structured data logging using Firebase-based architecture. Tenant Isolation (important): Each gym will have a unique gym_id. All data (members, workouts, diet, progress) will be stored under this ID and enforced using Firebase Security Rules so no gym can access another gym’s data. Structure example: gyms/{gym_id}/members gyms/{gym_id}/workouts MVP Milestones (10 days): Day 1–2: Setup + auth + gym structure Day 3–5: Admin panel (members, workout/diet creation) Day 6–7: User app (dashboard + logging) Day 8–9: Progress tracking + charts Day 10: Testing + APK + documentation Deliverables: Android APK + full source code Admin + user app (4-tab flow) Secure backend with gym-level isolation Setup guide to create new gyms easily Demo walkthrough Cost: ₹10,000 I will ensure a clean, production-ready MVP with proper data security and future scalability.
