Rufier Test App is a desktop application developed using Python and Kivy. The application is designed to assess a person’s physical fitness and cardiovascular performance using the Rufier test, a widely used functional health assessment.
This project combines basic medical logic with a multi-screen graphical user interface.
The Rufier test evaluates heart performance under physical load.
The test consists of:
- Measuring pulse at rest
- Performing 30 squats in 45 seconds
- Measuring pulse twice during recovery
Based on these values, the application calculates the Rufier Index and provides an interpretation of cardiovascular fitness.
- Step-by-step guided test procedure
- Multi-screen interface with clear instructions
- Built-in timers for pulse measurement and exercises
- Automatic calculation of the Rufier Index
- Age-based interpretation of results
- User-friendly desktop UI
- Language: Python
- Framework: Kivy
- UI: ScreenManager, layouts, widgets
- Logic: Custom Rufier index calculation
- Platform: Desktop
The application is organized into logical modules:
