Fitmate – Fitness App Development
Cross-platform Flutter fitness app with calorie tracking, workout planning, and integrated personal coaching.

Overview
NizSol developed a cross-platform Flutter mobile application for Fitmate, a wellness technology company that makes personalized fitness coaching affordable and accessible. The app combines calorie counter, workout tracker, progress monitoring, and integrated coaching into a single platform for iOS and Android.
All-in-One Fitness Platform
Fitmate needed a mobile app that combined nutrition tracking, exercise logging, and personal coaching in a seamless user experience. The challenge was delivering a feature-rich fitness platform that works offline, syncs across devices, and provides real-time coach-to-client interaction.
- Multi-Feature Complexity: Integrating calorie tracking, exercise library, workout plans, and coaching into one cohesive app.
- Coach-Client Interface: Building a real-time communication and progress monitoring system between trainers and clients.
- Cross-Platform Parity: Delivering identical functionality on iOS and Android with a single Flutter codebase.
Flutter Fitness Platform
We built a comprehensive Flutter mobile application with photo-based calorie entry, video exercise library, customizable workout plans, and an integrated coaching dashboard.
- Calorie & Macro Tracking: Photo-based food entry with intelligent macro-nutrient tracking and daily goal monitoring.
- Exercise Library: Video demonstrations with muscle-group tagging, set/rep logging, and progress tracking.
- Coaching Interface: Real-time coach-to-client messaging, progress monitoring, and personalized plan adjustments.
