No more struggling, no more burnout. What you need isn't harsher self-discipline, but smarter rhythm. Supports iPhone/iPad/MacOS. Supports iPhone/iPad/MacOS. I. Core Principles 1. Neural Replay Mechanism Latest neuroscience research shows that inserting a few seconds of random rest during focus periods causes the brain to replay previous information at 20x speed, a phenomenon known as "Neural Replay." —"Replay of Learned Neural Firing Sequences during Rest in Human Motor Cortex" 2. Variable Ratio Reinforcement The "variable ratio reinforcement" mechanism every 3-5 minutes, like drawing cards in games, creates an addictive feeling towards focus. 3. BRAC Physiological Rhythm Model Work cycles are recommended to be kept within 90 minutes, followed by 15-20 minutes of deep recovery rest (such as meditation, closing eyes, light activity), keeping you efficient throughout the day without exhaustion. —"Why I Can Study 10 Hours Daily" by Bilibili UP Master Zeen This is the core logic of "Interval Flow" - scientifically distributing attention rhythm, sustainable without consumption. In short, "Interval Flow" is not just another timer tool, but a scientifically supported cognitive rhythm training method. It helps your brain automatically enter focus flow at the right rhythm, learn faster, and perform better. *Note: During breaks, it's recommended to replenish sodium and potassium ions. Avoid using phones or playing games as they consume brain vitality. Recommended activities include meditation, daydreaming, light exercise, and listening to soft music. III.
