Note

I've created a design demo for the upcoming app! Feel free to check it out!

"Forgetting Ebbinghaus Curve" (working title) is an open-source iOS and macOS application for creating text-based notes (with plans to support other media types) designed to enhance information retention based on the Ebbinghaus forgetting curve. The application is currently in early development stages, with core features yet to be implemented. It's worth noting that this application will remain completely free and open-source throughout its development lifecycle and ongoing maintenance.

The codebase is organized into logical folders under Forgetting_Ebbinghaus_Сurve/:

Roadmap / TODO

• Initial project setup
• Basic note creation
• "Smart" notifications system (Smart notifications that consider input text size, time of day, and various other important parameters)
• Flashcard generation
• Adaptive learning algorithm (based on input text length, enabling efficient studying for both short snippets and lengthy documents)
• PDF support (for importing and working with PDF files)
• AI-powered context (providing additional insights for studied materials via built-in neural network)
• Add standart tests
• Multi-language support (beyond English)
  • Russian
  • French
  • Spanish
  • Italian
• Complete README (documentation with detailed installation and usage instructions)
• Add UI interface, showed in demo
• Add UI tests
• Add multiple media types support (in long plan)
