“Endless Info” is a game-style Information I learning app focused on making concepts like pseudocode, conditionals, loops, and binary/decimal conversion feel smooth and satisfying to solve. Instead of feeling like a traditional study app, it avoids heavy explanations and rigid academic vibes as much as possible. With a clean white-based UI and fast, responsive interactions, the app is designed to let you process problems in a quick, comfortable rhythm. There are two main modes: Endless Mode and 10-Question Time Attack. You can either take your time and carefully trace through logic, or enjoy solving problems at speed. Difficulty levels are also available, making it easy to gradually level up from basic processing concepts. Problems are presented using pseudocode and diagrams, asking questions such as: “What is the final value?” or “What will be output?” Answers can be selected or entered intuitively, and correct responses immediately lead into the next problem with light feedback and smooth transitions. Rather than focusing on long explanations, the app emphasizes the feeling of tracing and understanding the flow itself. Your results — including correct answers, streaks, and completion times — are recorded and viewable on the Stats screen. The overall design encourages relaxed, sustainable practice without pressure. The goal is to make Information I feel approachable without oversimplifying the actual logic. Don’t overthink it — just start tracing through the process. That’s the experience “Endless Info” aims to provide.
