Project Summary

Abstract

Living with diabetes requires continuous daily decisions, including checking blood glucose, estimating carbohydrates, selecting meals, calculating insulin guidance, and remembering follow-up checks. These tasks can become difficult when users rely on memory, paper notes, or separate tools, and mistakes may affect daily safety and confidence.

DiabeCare addresses this problem by providing a smart mobile application that combines the main diabetes self-management activities into one connected workflow. The system supports blood glucose tracking, meal logging, carbohydrate calculation, insulin dose guidance, follow-up reminders, Low Rescue assistance, Daily Log, Weekly Overview, Guardian Mode, AI Insights, and administrative food management.

The application was developed using Flutter with Firebase and Supabase services to support secure authentication, cloud storage, real-time synchronization, and AI-based insight generation. It was evaluated through functional testing and questionnaire-based usability feedback, where users responded positively to screen clarity, design, and feature usefulness.

As an outcome, DiabeCare presents a safer, more organized, and more supportive diabetes management experience, especially for users who need structured guidance and caregiver monitoring.

About Project

About DiabeCare

Project Idea

DiabeCare was developed as a senior project to help users manage Type 1 diabetes more safely and clearly. The application focuses on daily diabetes decisions such as checking blood glucose, selecting meals, calculating carbohydrates, receiving insulin guidance, and reviewing previous records.

The Problem

Many people with Type 1 diabetes need to make several decisions every day, including monitoring blood glucose, estimating carbohydrates, calculating insulin doses, and remembering follow-up checks. These tasks can become stressful, especially for children and users who need guardian support.

Project Objectives

Clear Goals of DiabeCare
