✨ Key Features

AlgoRecall is packed with features designed to streamline your interview preparation and maximize retention.

Feature	Description	Screenshot
🧠 Smart Revision System	Get a daily, personalized list of problems to revise. Our algorithm schedules problems based on your past performance and confidence levels to interrupt the "forgetting curve."
📊 Analytics Dashboard	A comprehensive dashboard provides a visual overview of your progress, including problem distribution by difficulty, status breakdown (Mastered, Revisiting, Pending), and your daily revision streak.
🗂️ Centralized Problem Hub	Log problems from any platform (LeetCode, HackerRank, etc.) with details like difficulty, tags, and company-specific questions. Keep all your notes and solutions organized in one place.
⚙️ Customizable Sessions	Tailor your revision sessions to your needs. Focus on specific topics (e.g., "Dynamic Programming"), companies (e.g., "Google"), or a combination of both to target your practice.
🔐 Secure Authentication	Full user authentication system with email verification, password reset, and secure session management using JSON Web Tokens (JWT) to keep your data private and personalized.
