FitnessApp

Overview

FitnessApp is a cross-platform mobile application developed using .NET MAUI that helps users track their fitness activities, monitor calories burned, manage exercise goals, and get real-time weather-based workout suggestions. The app offers a clean, user-friendly interface and is ideal for users who want to improve their health by logging daily exercise, setting targets, and calculating BMI.

Motivation

The app was built as part of a coursework project aimed at integrating multiple development skills:

Mobile application development with .NET MAUI
SQLite database integration
REST API consumption
User interface design for health and fitness tracking

The motivation stems from the increasing importance of fitness tracking in people’s everyday life. This app combines basic health tracking (weight, BMI) with real-time weather-based advice and persistent storage of workout history.

Key Features

Here’s what the user can see and do in the demo video:
