Managing a gym involves more than keeping the equipment in good shape. You also need to track memberships, record attendance, manage trainers, schedule classes, collect payments, and stay in touch with members. Handling everything manually can quickly become time-consuming as your gym grows.

FitForge brings these everyday tasks together in one platform. It includes a Django REST API backend, a Next.js web dashboard for gym owners and staff, and a Flutter mobile app for members. Whether you are running a single fitness studio or planning to build your own fitness software business, FitForge gives you a starting point you can customize to suit your needs.

You get the source code, can deploy the platform on your own server, and can adapt its branding and features for your business.

How FitForge Works

1. Manage Your Gym from the Web Dashboard

The web dashboard gives owners and staff a central place to manage daily gym operations. You can create membership plans, manage member accounts, review attendance, monitor upcoming renewals, assign diet plans, and keep track of classes.

Access is based on user roles, so everyone can focus on their responsibilities. Owners have access to gym management features, trainers can work with their assigned members and schedules, and staff can handle routine tasks without needing access to every administrative setting.

2. Give Members a Dedicated Mobile App

FitForge includes a Flutter mobile app for Android and iOS. Members can use it to check their membership status, view attendance history, browse class schedules, and access their assigned diet plans.

They can also book or cancel classes, renew memberships through Razorpay, access their personal QR code for gym check-ins, and record progress measurements such as weight and body fat. Progress charts help them review changes over time.

The app uses Riverpod for state management and features an Obsidian Gold design, combining dark backgrounds with gold accents for a consistent, modern look.

3. Handle Membership Payments in One Place

FitForge integrates with Razorpay to support membership payments and renewals. Members can initiate renewals from the mobile app, while authorized staff can process them through the web dashboard.

Test mode and mock payment mode are also available. This makes it easier to demonstrate the platform, test payment flows, and develop locally before configuring live payment credentials.

Who Can Use FitForge?

Gym Owners and Fitness Studio Managers

If you manage a gym, CrossFit box, yoga studio, or boutique fitness centre, FitForge can help bring membership records, attendance, payments, and class schedules into one system.

You can host the software on your own infrastructure and adapt it to your business processes. Owning the source code also gives you more control over future changes compared with relying entirely on a subscription-based platform.

Fitness Technology Startups

Building a fitness management product from scratch means spending time on authentication, APIs, dashboards, mobile screens, payment integration, and other core features before you can focus on your own product idea.

FitForge gives you an existing codebase to build on. You can customize its appearance, extend its functionality, and shape it into a product that fits your target market.

Software Development Agencies

Agencies working with gyms and fitness businesses can use FitForge as a foundation for client projects instead of developing every common feature from the beginning. Depending on the client's requirements, the existing platform can be branded, configured, and extended before delivery.

SaaS Founders and Multi-Location Businesses

FitForge includes a multi-tenant-lite approach that scopes queries to the authenticated gym. This provides a starting point for businesses that want to explore a multi-location or SaaS model.

However, supporting multiple independent customers in a production SaaS environment may require additional work, including tenant isolation, permissions, billing, onboarding, and security testing. Those requirements should be reviewed before launching a shared multi-tenant deployment.

Practical Ways to Use FitForge

For a Single Gym

A gym can use FitForge to replace scattered spreadsheets and manual attendance registers with a central system. Staff can record check-ins, review membership expiry dates, and manage renewals from the dashboard, while members use the mobile app to access their own information.

For a Fitness Business with Multiple Locations

A business with several branches could deploy separate instances for individual locations, giving each branch its own operational environment. This approach requires appropriate server configuration, backup procedures, and access controls for every instance.

For a Fitness Startup

A startup can customize the existing dashboard and mobile app, introduce its own branding, and add features that distinguish its service. This can reduce the amount of foundational development required before testing the product with potential customers.

For an Agency Building a Custom Solution

An agency can adapt FitForge to a client's workflow, whether that means changing the dashboard design, extending reporting, or modifying how bookings and attendance are handled. The final development effort will depend on how closely the client's needs match the existing features.

Why Start with FitForge Instead of Building from Scratch?

A gym management platform involves several connected parts: authentication, role permissions, membership management, payment processing, attendance, class bookings, a web dashboard, and a mobile application. Building and testing all of these components takes considerable development time.

FitForge gives you an existing implementation of these core workflows, so you can spend more time adapting the product to your requirements rather than starting with an empty project.

The actual time and cost savings will depend on your team, deployment environment, and the changes you need. You should also account for testing, maintenance, hosting, payment gateway charges, and any third-party messaging costs when planning your budget.

If your business needs additional functionality, such as a customized billing process, new user roles, or specialized reports, you can build on the existing codebase. Contact CodeAj Startup for customization services to discuss your requirements.
