The laptop is where you grind a full problem. The phone is where you learn which tool the brief is asking for. Lattice names the core sections of data structures and algorithms and quizzes you on them. A break is recognize, diagnose, reconstruct. Smell names the tool from an unlabeled brief. By the time you sit down to a problem set, you already have the map. Progress stays on the phone. A break Recognize. Name the pattern from a tight prompt and a strip of code. Diagnose. Find the stall: bound, structure, or walk. Reconstruct. Put the move back in order from tokens or blanks. Smell A separate gym. Name the tool from a brief with the label stripped. On the phone The pack ships in the app. Scores and review live on the device. You do not need an account. Offline. A spare minute is enough. Made by Embedded Nature.
