Your focus pays for your screen time. Regrind keeps the apps you choose locked until you've earned the time. Focus sessions pay Credits into your balance. Withdraw them to unlock your apps, and they lock again when the time runs out. It isn't a timer that only blocks apps while you work. When people set up Regrind, more than 6 in 10 say they spend 4+ hours a day on their phone, 8 in 10 say they scroll too much, and nearly 2 in 3 have already tried screen time limits. Limits are easy to dismiss. In Regrind, time on blocked apps must be paid for in Credits. HOW IT WORKS 1. Choose which apps and websites Regrind locks. They stay locked, no schedule needed. 2. Start a focus session. Every minute you complete earns Credits for your balance. 3. Withdraw Credits from your balance to unlock your apps for a fixed time. AS OF SEPTEMBER 2026 - 100,000+ hours of focus sessions completed - Nearly 400,000 unlocks paid for in Credits FEATURES - Block List: choose which apps, websites and whole categories stay locked - Uninstall Protection: while your blocks are on, no app can be deleted from your device, Regrind included - Screen-Off Sessions: keep earning Credits while your phone is locked - Motion Detection: move your phone too much and you lose the session - AR Lock Box: lock your phone in an augmented reality vault while you focus - Scratch Coupons: finish a session to reveal bonus Credits, paid straight to your card - Focus Card: holds your Credits, labeled with what you're saving toward - Focus Score: a credit score for your focus, based on how many earned Credits you keep each day - Transaction History: every session and unlock, itemized like a bank statement - Exchange Rate: set how many Credits screen time costs - Daily Spending Limit: cap how much screen time you can unlock each day - Withdrawal Security: confirm each withdrawal with Face ID or Touch ID - Friends and Leaderboards: see friends' balances, compare focused hours and compete to be the week's top card holder - Widgets and Live Activities: check your balance, start sessions and track progress from your Home Screen and Lock Screen Some features require the Premium plan, available as an in-app purchase. BUILT FOR - Students protecting study time - Anyone who scrolls more than they mean to - Anyone who's turned off a blocker in a weak moment - People with ADHD who find their phone hard to put down PRIVATE BY DESIGN Regrind uses Apple's Screen Time API. Your Screen Time data stays on your device, protected by Apple, and Regrind can't see which apps you use or for how long. Friends and leaderboards need you to sign in; the Privacy Policy explains what that shares.
