Practice algorithms without accounts, cloud services, or subscriptions. Algorithms Pro is a native, fully offline coding practice app. Work through 150+ problems across 20 categories, from an approachable on-ramp through hard graph, dynamic programming, systems, and design exercises. - Browse and search a catalog by difficulty, category, and solved state - Read precise problem statements, input and output rules, and examples - Write and keep multiple C solutions for each problem - Run complete visible and hidden deterministic test decks - Inspect source-synchronized disassembly beside your code - Compare tests passed, instructions executed, and code size The sandboxed virtual machine has no clock, randomness, network, or host access. All progress and solutions stay inside the app container on your system.
