Brevia teaches data structures and algorithms from zero — calmly, one idea at a time — then helps you remember them for good. Most resources throw a wall of theory or an endless queue of problems at you. Brevia is different: a guided journey that explains each concept in small, focused cards, checks your understanding with a quick question, then uses spaced repetition so what you learn actually sticks. WHAT'S INSIDE • A guided journey from Foundations to Advanced — Big-O, two pointers, recursion, binary search, sorting, trees, graphs, dynamic programming and more. • Bite-size lessons, one idea per card: concept, intuition, a worked example, a pro tip, a quick checkpoint and a recap. • Adaptive quizzes that meet you at your level and grow as you do. • Spaced repetition and streaks, so concepts move into long-term memory instead of fading. • A Big-O complexity reference for fast re-orientation. • Visual mindmaps for every topic. • "Learn how to learn" tips grounded in real cognitive science. CALM BY DESIGN No noise, no endless feeds, no pressure — just a clear path, a gentle pace and progress you can feel. A COMPANION TO YOUR PRACTICE Brevia is the understand-it-first layer: the calm on-ramp before you grind problems on LeetCode and friends. Learn the idea here, then go apply it with confidence. FREE, NO CATCH Brevia is completely free — no ads, no subscriptions, no paywalls. If it helps you, an optional Tip Jar lets you support development. Entirely up to you. Your progress syncs privately across iPhone and iPad with iCloud. No accounts, and Brevia collects no personal data.
