TL;DR

Gym owners are being bled dry by a Frankenstein stack of 7+ disconnected tools: Mindbody for scheduling, separate door fobs, Stripe for payments, Mailchimp for emails, and more. We didn’t “integrate” them—we obsoleted them. We built Fitovision: a cloud-native platform powered by MERN stack (MongoDB, Express.js, React, Node.js) on AWS, with a React Native mobile app that acts as a member’s key, wallet, and ID. The result? 95% operations automated, one subscription fee replacing seven, and member retention that skyrocketed because the experience is frictionless.

The Mission

Fitovision entered the Croatian market with a mission to help gym owners set up digital gym presence and take control of their operations. The goal was to replace the chaotic multi-tool ecosystem with one unified platform.

The Challenges We Solved

Challenge 1: Design Logo and Brand Identity

The Problem: Fitovision needed a brand identity that conveyed innovation, fitness, and technology. The logo needed to work across web, mobile apps, and physical access devices.

Our Solution: We designed a complete brand system using Figma:

  • Modern, tech-forward aesthetic appealing to gym owners and members
  • Scalable logo system working from app icons to large signage
  • Fitness-inspired color palette (energetic, motivating, professional)
  • Typography system ensuring readability across all platforms
  • Brand guidelines for consistent application across touchpoints

The brand identity positioned Fitovision as the modern, tech-savvy solution for gym management.

Challenge 2: SEO Website Architecture

The Problem: As a new brand in the Croatian market, Fitovision needed to rank for competitive gym management software keywords. Without proper SEO, they’d be invisible to gym owners searching for solutions.

Our Solution: We built an SEO-first architecture:

  • Keyword strategy targeting “gym management software Croatia,” “fitness studio software,” and related terms
  • Technical SEO optimization ensuring fast load times and mobile responsiveness
  • Content strategy creating valuable resources for gym owners
  • Local SEO optimization for Croatian market targeting
  • Internal linking connecting service pages and blog content

This SEO architecture, following our SEO service methodology, helped Fitovision dominate search results in the Croatian fitness market.

Challenge 3: Design Website

The Problem: The website needed to explain a complex SaaS platform in simple terms, convert gym owners into trial users, and build trust in a new brand.

Our Solution: We designed a conversion-focused website using React:

  • Clear value propositions showing how Fitovision replaces 7+ tools
  • Interactive demos letting gym owners see the platform in action
  • Social proof (testimonials, case studies, user counts)
  • Pricing transparency building trust with clear subscription tiers
  • Mobile-responsive design ensuring perfect experience on all devices

The website design, following our web design principles, achieved a 12% conversion rate from visitor to trial signup.

Challenge 4: Multi-Tenant Architecture on Backend

The Problem: Fitovision needed to serve multiple gyms (tenants) from one platform, with complete data isolation between gyms while sharing infrastructure efficiently.

Our Solution: We architected a robust multi-tenant system using Node.js and MongoDB:

  • Tenant isolation ensuring complete data separation between gyms
  • Shared infrastructure reducing costs while maintaining security
  • Scalable database design using MongoDB’s flexible schema
  • Resource allocation preventing one tenant from impacting others
  • Billing system tracking usage per tenant for accurate invoicing

The multi-tenant architecture, built with our SaaS development expertise, allows Fitovision to scale to thousands of gyms without performance degradation.

Challenge 5: WDMS - Remotely Device Controlling (SMART Gym)

The Problem: The most audacious challenge: complete remote control of physical gym access. Not just a digital membership card, but the ability to open doors from anywhere in the world.

Our Solution: We engineered a cloud-based Workout & Door Management System (WDMS):

  • Cloud-first architecture moving all logic to AWS
  • Secure persistent connection between cloud WDMS and on-site access controllers
  • Real-time command system sending “OPEN” commands in under 2 seconds
  • Offline fallback ensuring doors work even if internet temporarily fails
  • Security protocols preventing unauthorized access attempts

The WDMS, deployed on AWS infrastructure, achieved 99.99% uptime and revolutionized how gyms control physical access.

Challenge 6: CRM - Member Management System

The Problem: Gym owners needed a comprehensive CRM to manage members, track attendance, handle communications, and analyze member behavior.

Our Solution: We built a custom CRM integrated with the platform:

  • Member profiles storing complete information and preferences
  • Attendance tracking automatically logging check-ins via mobile app
  • Communication hub managing emails, SMS, and push notifications
  • Analytics dashboard showing member retention, peak hours, and trends
  • Automated workflows for membership renewals and follow-ups

The CRM, built with our automation capabilities, eliminated manual member management tasks.

Challenge 7: QR Scan System

The Problem: Members needed a quick, contactless way to check in and access facilities without physical cards or fobs.

Our Solution: We implemented a QR code scanning system:

  • QR code generation unique to each member in the mobile app
  • Scanner integration in access controllers and front desk systems
  • Instant verification checking membership status in real-time
  • Contactless experience improving hygiene and convenience
  • Analytics tracking logging all scans for attendance data

The QR system, combined with the React Native mobile app, provided a seamless, modern check-in experience.

Challenge 8: Subscription System

The Problem: Fitovision needed a flexible subscription system handling multiple pricing tiers, billing cycles, and payment methods for both gym owners and their members.

Our Solution: We built a comprehensive subscription management system:

  • Multiple pricing tiers (Basic, Pro, Enterprise) for gym owners
  • Member subscription management allowing gyms to set their own pricing
  • Automated billing processing payments on schedule
  • Payment gateway integration supporting multiple payment methods
  • Subscription analytics tracking MRR, churn, and growth metrics

The subscription system, following our SaaS development best practices, handles thousands of subscriptions reliably.

Challenge 9: Email Marketing - Automated Email Sequences

The Problem: Gym owners needed automated email campaigns for member onboarding, retention, promotions, and re-engagement without manual work.

Our Solution: We built automated email marketing using AWS SES:

  • Welcome sequences for new members
  • Retention campaigns for inactive members
  • Promotional emails for special offers and events
  • Automated reminders for membership renewals
  • Personalized content based on member behavior and preferences

The automated email system, part of our automation service, saved gym owners 10+ hours weekly while improving member engagement.

The Technical Stack

We built Fitovision using modern, scalable technologies:

  • Frontend: React for web dashboard, React Native for iOS and Android apps
  • Backend: Node.js with Express.js for API development
  • Database: MongoDB for flexible, scalable data storage
  • Cloud Infrastructure: AWS (EC2, S3, SES, RDS) for reliable hosting
  • Design Tools: Figma for UI/UX design
  • Architecture: MERN stack for full-stack development

This stack ensures scalability, reliability, and the ability to serve thousands of gyms simultaneously.

Results: From Chaos to Command

  • 95% automation of gym operations
  • One platform, one fee replacing 7+ separate subscriptions
  • 30% reduction in software costs for gym owners
  • 45% increase in member retention
  • 4.9/5 star app rating on app stores
  • 5-star verified client satisfaction
