Desenvolvimento do aplicativo Gym Tracker

Abstract

Training consistently requires logging exercises, sets, and routines, but many people struggle to maintain an organized history and update workouts conveniently, especially when offline or needing to correct past records. To address this problem, this work proposes the development of a mobile application that facilitates workout planning, logging, and tracking, allowing users to create and reuse routines, adjust exercises and sets, and register workouts retroactively. The solution was built following an incremental process, with requirements elicitation and prioritization, data and use-case modeling, and implementation in Flutter using reactive state management and local persistence in a local-first approach, ensuring operation without continuous network dependency. The application was validated through manual testing on real Android devices, which verified the integrity of operations and data consistency, demonstrating technical feasibility, reliable offline functionality, correct history maintenance, and adherence to the defined requirements.
