Our Mission
AlgoHay was created to help computer science students and developers master algorithm complexity analysis. We believe that understanding Big O notation, recursion trees, and time-space tradeoffs is fundamental to becoming a great programmer. Yet these concepts are often taught abstractly without practical tools to verify understanding.
Our mission is to bridge that gap. We provide free, accurate, and easy-to-use calculators that make complexity analysis concrete. Whether you're studying for exams, preparing for technical interviews at FAANG companies, or optimizing production code, our tools help you understand algorithms deeply.
What Makes Us Different
Accuracy First: Our calculators use proven computer science formulas and theory. Every result is based on established algorithms and complexity analysis techniques, not approximations.
Educational Focus: Each tool includes 2000+ words of educational content explaining the theory, examples, and common pitfalls. We don't just give you an answer - we help you understand why.
User-Friendly Design: Clean, modern interface that works perfectly on mobile, tablet, and desktop. No clutter, no distractions - just professional tools that work.
Always Free: No paywalls, no premium features, no subscriptions. Everything is free because education should be accessible to everyone.
Privacy Respected: No login required, no tracking beyond basic analytics, your calculations stay private. We focus on tools, not data collection.
