Build timing skill through short, fully visual rhythm sessions. Follow original beat patterns across three lanes and tap each marker when it reaches the judgement line. Every exercise works offline and remains clear with sound turned off. Explore four chapters and 40 lessons that gradually introduce steady single taps, alternating lanes, simultaneous double taps, syncopated patterns, and short holds. Lessons last 45 to 75 seconds and include a visual count-in before play. During a session, follow your progress and combo while receiving immediate timing feedback. At the end, review your judgement counts, timing tendencies, lane-by-lane results, and the 15-second segment that needs the most practice. Replay that focused segment or repeat the full lesson. Personalize the experience with an optional device-only timing calibration, left-hand lane order, reduced motion, a larger judgement line, lane patterns, and optional click or haptic feedback. Visual markers keep every beat readable without sound. Lesson progress, results, calibration, and preferences stay on your device. No account, network connection, external songs, or background audio is required.
