Block Reels, Shorts and For You, and keep your messages. Every feed blocker in Fluid Friction is free. Then go further: open Instagram, TikTok, YouTube, Reddit, X, Snapchat, Facebook or LinkedIn inside Fluid Friction, or add any website you choose, and the feed pushes back. Fluid rises from the edge of the screen against your thumb. Drag through it until a bubble forms and rises off the screen. Only then does the next post arrive. Cross the threshold on purpose, or set the phone down. It doesn't shame you. It just makes you mean it. WHY IT WORKS Infinite feeds run on autopilot. Fluid Friction slips one deliberate moment between you and the scroll, so doomscrolling becomes a decision instead of a reflex. The friction lives inside the scroll itself. Dial it from gentle to intense, set scroll limits per app, and let YouTube friction fire on Shorts only. CALM SHIELDS FOR YOUR OTHER APPS Block any native app, or a website, with Screen Time. Instead of a wall of shame you get a calm, warm screen, a clear count of the opens you chose to keep, a cooldown between opens, and a breathing, math or passphrase moment before you go in. Timed sessions count down right in the Dynamic Island and the shield returns when time is up. One toggle also blocks adult websites. Strict when you ask for it, dignified always. KEEP THE CHATS, SKIP THE RABBIT HOLE Hide Reels, Shorts, Stories, Explore and For You while messages keep working. Open apps to a calmer landing page, follow only the people you chose, hide recommendations and comments on YouTube, or go grayscale across every feed. Multiple accounts with separate sessions are built in, so the calmer way is also the comfortable way. TAP & SCAN Turn any NFC tag you already own into a physical key (NFC on iPhone): a sticker, a card, even a transit pass. Tap to lock your distracting apps, tap to release them, or require a scan to unlock a shield. No extra hardware to buy; a QR code or a barcode in your kitchen works too. WAKE UP WITHOUT THE FEED An alarm that ends with a scan, not a scroll. Dismiss it with your tag or a barcode across the room, answer a quick wake challenge, and let a morning block hold the feeds until you are up. Wind down at night, track your wake streak, and earn 25 honest milestones. On iOS 26 the alarm rings like the built-in clock; on earlier versions it alerts through notifications. SEE YOURSELF CLEARLY A Calm Score reflects how your scrolling actually went. Real Screen Time numbers, weekly recaps, and tailored suggestions you can apply with one tap, like a schedule for the hour that always gets you. FOCUS WHEN IT COUNTS Focus timer, Pomodoro sessions, and a Focus Bank that turns focused minutes into earned, deliberate breaks. Breaks keep the feeds blocked by default, and the countdown lives in the Dynamic Island. ON IPAD AND APPLE WATCH Fluid Friction now runs natively on iPad, with calm feeds, shields and insights laid out for the bigger screen. On iPad, your key is a QR code or a barcode. On Apple Watch, start a focus session, lock your apps now, see and set your alarms, and keep your wake streak. The blocking itself runs on your iPhone. MAKE IT YOURS 91 bubble themes, from aurora to plasma, with mystery unlocks and matching app icons. Home screen widgets too, including a minimalist launcher that routes tempting apps through the wave. PRIVATE AND FAIR No ads. No tracking. Your usage stays on your device. Every tool is free: the friction, the shields, the alarm, the insights. Fluid Pro, if you ever want it, unlocks themes and comfort extras like dark mode, with a 7 day free trial.
