AlgoPattern vs Stepwise

AlgoPattern helps you build pattern recognition for coding interviews through short, focused DSA practice. Instead of jumping straight into full coding problems, train the skill that comes first: recognizing which algorithmic pattern a problem is testing. Complete a quick practice session featuring common patterns such as Two Pointers, Sliding Window, Hash Maps, Binary Search, and more. Review short explanations, track your progress, and build stronger coding interview instincts one small session at a time. WITH ALGOPATTERN, YOU CAN: • Complete a focused daily quiz • Practice common data structure and algorithm patterns • Answer interview-style multiple-choice questions • Review explanations after each answer • Track your streak, XP, accuracy, and practice history • Compete on weekly and all-time leaderboards • Unlock unlimited practice with AlgoPattern Pro AlgoPattern is designed for students, aspiring software engineers, and early-career developers who want a more approachable way to prepare for LeetCode-style technical interviews. Whether you are just beginning to study data structures and algorithms or want to stay consistent between longer practice sessions, AlgoPattern turns spare minutes into meaningful interview preparation. A subscription is required to access Pro features. Monthly, yearly, and lifetime plans are available. AlgoPattern is an independent app and is not affiliated with or endorsed by LeetCode.

Don't watch BFS run. Be BFS. Stepwise is a daily training game for software engineers, built for a phone: tap, drag and swipe. There's no typing on a tiny keyboard. BE THE ALGORITHM Execute real algorithms by hand on freshly generated inputs. Tap nodes in the order breadth-first search visits them, pick which node Dijkstra settles next, sift a value through a heap, probe a sorted array like binary search. Every move is scored, and the puzzles never run out. THE DAILY SET Five challenges, the same for every developer that day. Keep your streak and share a spoiler-free result card. A RATING THAT MEANS SOMETHING Every topic has its own Elo, like chess puzzles. Difficulty adapts to you. MORE GAMES Big-O Blitz, Bug Hunt, Line Up, Output Oracle (Java, Python, SQL), Pick the Structure and Pattern Spotter. There is also an Engineering track: race conditions, SQL traps, index choice. Every answer is checked: generated puzzles take their answer key from the real algorithm, and code snippets are verified by actually running them. Challenge a friend with a link to the exact puzzle you just solved. Your full history is saved, so you can replay anything you missed.
