InterFlow vs Sit Still

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.

Sit Still is a focus timer and app blocker that gives you somewhere to be. Most focus apps punish you, Sit Still keeps you company. A cat sleeps in a painted room while you work, and the reward for sitting still is a collection you build. Blocking is real, and as firm as you want it to be. The rooms are the heart of it: watercolour illustrations painted like the pages of a childhood picture book, meant to feel cozy and nostalgic — to stir a memory of being small and safe somewhere — each with its own soundscape. APP BLOCKING FEATURES Three app blocking modes for a focus session: Open, Whitelist and Strict. Additionally, app blocking rules allow you to put away the apps that keep distracting you throughout the day. You can lock the apps on a schedule of your own or hold them to a daily limit. You can also set a bedtime lock on a night schedule you choose. WALLPAPERS AND WIDGETS Any room you have can be saved to your Photos as a wallpaper, drawn at the full resolution of your phone or iPad, with your cat in the corner or without it. There are widgets too: the room you are sitting in with your focus stats under it, the collection with a different room every hour, a calendar of the month with your cat beside it, and your streak on the Lock Screen and in StandBy. A TIMER WITH THREE SHAPES Countdown, open-ended, or pomodoro. The pomodoro starts at the classic 25 / 5 / 15, and all three lengths are yours to change. A session carries on with the screen locked, and shows itself on the Lock Screen and in the Dynamic Island. A COLLECTION OF ROOMS A permanent collection of rooms, from a bookshop loft in Porto to a stilt house on the Mekong Delta, and two new rooms on the first of every month that leave with it. Every room has its own illustration and its own ambience loop, levelled against all the others so changing rooms is never a lurch. On iPad, every room opens out into a wide painting, upright or sideways. A CAT, AND THINGS FOR IT TO WEAR Six companions, hand-drawn and animated. Focusing earns whiskers, and whiskers buy cat accessories and the monthly rooms. Pet the cat and it notices. WHAT YOU NEED TO DO, AND WHAT YOU DID A task list that stays in sync with your phone's own Reminders. A record of every session — hours, streaks, and the note you left about what you were working on.
