AlgoMaster organizes technical interview preparation into lessons, curated problem sets, and visual explanations. Learners can practice data-structure and algorithm patterns such as binary search, trees, graphs, and dynamic programming, then move into system design topics including caching, queues, databases, sharding, and scalability. The app also covers low-level design, microservices, and distributed systems, with quizzes and progress tracking to revisit difficult material. It is free to download, but the US App Store lists Premium at $34.99 per month, $89.99 per year, or $179.99 for lifetime access. The app currently has a small review sample, so prospective learners may want to inspect the available lessons before subscribing. Apple’s privacy label says contact details, user content, search history, identifiers, usage, and diagnostic data may be linked to the user. AlgoMaster teaches interview concepts; it does not guarantee job outcomes.
