JustFocus: Pomodoro & Tasks
JustFocus is a productivity application designed to help you manage your time effectively using the Pomodoro Technique. Built with Flutter, it combines a customizable timer with an integrated to-do list, keeping you focused and organized throughout your workday. Whether you're studying, working remotely, or juggling freelance projects, this app is designed to help you stay productive and avoid burnout.
Overview
- Platform: Android (iOS compatible architecture)
- Technologies: Flutter, Dart, Kotlin, BloC, SQLite
- Development Context: Professional project published on Google Play Store
- Architecture: Clean Architecture with layered separation
Project Highlights
JustFocus demonstrates professional mobile development through several key architectural decisions. The app keeps your timer running seamlessly in the background using native Kotlin services, sending persistent notifications so you always know your remaining time. Behind the scenes, a hybrid state management approach combines BloC for complex operations (timer management, task handling) with ValueNotifier for lighter UI interactions, ensuring both robustness and performance. All your data—tasks, sessions, and preferences—is stored locally on your device using SQLite, so the app works perfectly offline without relying on internet connectivity.
The foundation is built on Clean Architecture principles, organizing the codebase into distinct layers: Presentation handles the UI, Domain contains business logic and use cases, and Data manages repositories and storage. This separation makes the code highly testable, maintainable, and scalable. Everything is designed to work reliably on any device, offline functionality, and user experience. The result is a productivity tool that combines technical excellence with genuine usefulness.
Final Considerations
JustFocus demonstrates how professional mobile development combines clean architecture with practical features that users genuinely need. The focus on offline functionality, background service integration, and thoughtful state management results in an app that's both technically sound and reliable in real-world conditions.
You can download JustFocus on the Google Play Store and experience how Flutter and native Android code can work together to create a productive tool that helps you focus better and accomplish more.
