Stundio (ˈstuːndio, like "stundu" in Latvian) is a next-generation mobile and web experience for EduPage, engineered for students who demand performance, usability, and modern design. We transform the often rigid and outdated educational interface into a fluid, high-performance tool that works seamlessly across all devices.

EduPage has significant UX issues that impact daily student usage:

• Lack of persistence: selected groups and settings are often lost
• Outdated UI: not optimized for modern mobile devices
• Performance issues: slow loading and weak responsiveness
• Cluttered interface: unnecessary complexity for simple tasks

Stundio introduces a student-first approach:

• Persistent state (your group and settings are always saved)
• Liquid UI with smooth and modern animations
• High performance with optimized rendering
• Full local processing (no tracking, no analytics)

• Smooth animations and transitions
• Fast client-side rendering
• Cross-platform support (Android, iOS, Web)
• Minimal and student-focused interface

Stundio is built using a scalable feature-first clean architecture with Flutter, designed for long-term maintainability and cross-platform support.

The architecture follows strict SOLID principles, ensuring modularity, testability, and clean separation of concerns.

Presentation → Domain → Data

Each feature is fully independent and self-contained.

Contains shared logic used across the application.

• DI (Dependency Injection)
• Networking (API client, interceptors, endpoints)
• Routing (navigation system)
• Theme (colors, typography, design system)
• Error handling (exceptions, failures)
• Utilities (validators, helpers)
• Shared widgets (buttons, inputs, loaders)

Each feature follows the same structure: feature/ data/ domain/ presentation/

• API models (DTOs)
• Remote and local data sources
• Repository implementations

• Entities (pure Dart objects)
• Repository interfaces
• Use cases (business logic)

• UI screens
• State management (Bloc/Cubit)
• Feature-specific widgets

UI → State Management → Use Case → Repository → Data Source → API

• Strict separation of concerns
• Dependency inversion
• Feature isolation
• Reusable components
• Testable domain layer
• No business logic in UI

Made from students for students.

Stundio exists to eliminate frustration caused by outdated educational systems and replace them with fast, intuitive tools.
