YouDo is an Android productivity application designed to help users organize tasks, monitor time usage, and track daily activity in one unified system. The app combines task management, performance analytics, and physical activity tracking to support more balanced and effective daily routines.
Create, edit, and manage tasks with a structured lifecycle:
- Task creation with title, description, date, and optional target duration
- Mark tasks as completed while recording the actual time spent
- Edit or delete existing tasks
- Daily task overview with the ability to browse tasks from other dates
Tasks can be organized into customizable categories:
- Built-in default categories (e.g., work, sport, hobby)
- User-defined categories with custom names and colors
- Ability to delete unused categories
- Category-specific productivity logic
YouDo analyzes how effectively time is spent on tasks.
- Compares planned time vs. actual time
- Calculates category-based performance percentages
- Supports two productivity models:
- Overperformance rewarded (e.g., studying longer)
- Efficiency rewarded (e.g., completing tasks faster)
- Generates a Self-Discipline Score
- Displays motivational feedback messages based on performance levels
The app provides visual analytics to help users understand their productivity.
- Category-based bar charts
- Comparison of planned vs. completed time
- Performance percentage tracking per category
- Real-time updates when task data changes
YouDo integrates hardware sensors to track daily activity.
- Uses Android Step Counter and Step Detector sensors
- Runs as a Foreground Service to maintain accuracy
- Tracks daily steps even when the app is not open
- Automatically updates UI via broadcast messages
The app supports Google ecosystem integration.
- Google Sign-In authentication
- Secure OAuth2 authentication flow
- Synchronization with Google Calendar
- Tasks can be aligned with calendar events
The project follows a modular structure inspired by the MVC (Model–View–Controller) pattern.
Java (Android SDK)
- XML Layouts
- Material Design components
- Responsive interface structure
- SQLite – Local persistence and fast data access
- Firebase Firestore – Real-time cloud synchronization
- Firebase Authentication
- Google Sign-In (OAuth2)
- Android Sensor Manager
- Step Counter & Step Detector
Defines UI structure and visual components.
Handles user interactions and screen logic.
Core data objects:
UserToDoType(task categories)Step
Handle CRUD operations and database communication.
Performance is calculated by comparing planned task duration with actual time spent.
Two possible formulas are used depending on the category configuration.
performance % = (total actual time / total planned time) × 100
performance % = (total planned time / total actual time) × 100
Category results are aggregated into an overall Self-Discipline Score.
- >100% → Outstanding performance
- 100% → Perfect goal completion
- 50–99% → Moderate performance
- <50% → Improvement recommended
Application walkthroughs, diagrams, and screen recordings are available in the /Design directory.
Sensitive configuration files are excluded from the repository:
google-services.json- API keys
- SHA fingerprints
These must be generated in your own Firebase project.
Load the project and allow Gradle to resolve dependencies.
Ensure Android SDK API 33+ is installed.
Add your own google-services.json file to enable:
- Firebase Authentication
- Firestore
- Google Sign-In
Deployment is optimized for:
- Android 13 (Tiramisu)
- Android 14 (Upside Down Cake)
- AI-based task prioritization
- Exportable productivity reports (PDF / CSV)
- Improved historical analytics
- Extended compatibility for older and newer Android versions
This is a personal development project.
