Spaced repetition systems (SRS) like Anki optimize review timing based on memory decay models, but most ignore circadian biology. Emerging research (2025, *Sleep & Cognition Journal*) shows recall accuracy varies by up to 37% depending on time of day—e.g., factual recall peaks in late morning, while procedural memory consolidates better in evening reviews. Some apps now pilot 'chrono-adaptive SRS' that schedule reviews based on user chronotype and historical performance by hour. Critics argue this adds unnecessary complexity and may reduce consistency. With lifelong learning and upskilling accelerating, this trial asks whether integrating circadian science into SRS algorithms meaningfully boosts long-term retention or merely over-engineers a proven system.
