wanna scroll? do 67 first. 67 blocks the apps you open without thinking. to get in, you do the 6-7 gesture, hands in the air, counted by your camera. then 67 asks: still wanna scroll? say yeah, and the app opens for a few minutes. say nah, and it stays blocked. either answer is fine. the point is that you chose. HOW IT WORKS • pick the app that eats your time. • open it, and 67 is there instead. • prop your phone up and do the 6-7 gesture. • 10 reps for 5 minutes, up to 67 reps for 20. or back to your day. • the block comes back by itself, even if 67 is closed. NEW HERE? 3 DAYS OF 67+, FREE every new phone gets 3 days of 67+. no card, nothing charged when it ends. after that, keep 67+ or pick 1 app to keep blocking for free. FREE, FOREVER • 1 blocked app. you choose which. • blocking hours: block all day, or only the hours you pick. • pausing the block takes a 67 too. • no ads. no account. 67+ • all your bad apps: unlimited apps, plus categories and websites. • locked in: lock your own rules for 30 minutes, 1 hour, 2 hours, or until morning. while you're locked in there is no pausing, nothing comes off the list, every unlock takes 67 reps, and no app on the phone can be deleted. there is no undo until the time is up. 67 never charges you to weaken your block. PRIVATE BY DESIGN • camera frames are processed on your phone. nothing is saved or uploaded. • 67 can't read the names of the apps you block. apple keeps them hidden, from us too. • no account. usage stats are anonymous. 67 needs screen time access, which ios will ask you for, and the camera. iphone only. 67+ is a one-time purchase of $29.99, or an auto-renewing subscription: $19.99 a year or $4.99 a month. prices vary by region. payment is charged to your apple account at confirmation of purchase. subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. manage or cancel them in your apple account settings. terms: https://do67.app/terms privacy: https://do67.app/privacy

About

Arc Lock

Companies fight for every second of your time to keep you distracted. Taking control of your screen time should be a human right, not something locked behind a paywall. Arc Lock blocks the apps and websites that eat your day, and once a block starts, it stays on. Every feature is free for everyone: no subscription, no account, no ads, no in-app purchases. SCHEDULES Pick apps, app categories and websites, choose the hours and days, and they lock on their own. Overnight windows like 11 PM – 7 AM work too (up to 22 hours). DAILY LIMITS Allow yourself a set time each day, from 5 minutes to 8 hours. See exactly how many minutes are used and left. When the time is used up, those apps lock until the limit resets: at midnight, or at the time you pick (say 4:00 AM, for late nights). A heads-up comes 5 minutes before. TIME-OUTS Not a full block, a pause. After a stretch of use, the apps take a short break, then open again. For example: after 20 minutes of short videos, a 10-minute break. It repeats all day and starts fresh at its reset time. BLOCK NOW Lock distractions right away, from 15 minutes to 12 hours. The Block now button is always one tap away. PLACES Pick one or more places on the map, like the library, your school or the gym, and the apps lock when you arrive. Each place block ends when you leave, or after a set time, whichever you choose, and starts only on the days you pick. Location access is asked for only when you set up a place block, and Arc Lock never sends your location anywhere. STRICT LOCK Every block can have Strict lock, and it's on by default. While a strict block runs: • it can't be stopped, loosened or deleted in Arc Lock • the date and time can't be changed by hand • the block screen has a single button: Close Daily limits and time-outs are locked in until they reset: you can make one stricter once a day, but looser settings only start at its next reset. Want a gentler block? Switch Strict lock off for that block, and you can stop it whenever you like. Switching Strict lock off for the whole app works right away: a block that's running or counting stays strict only until its own reset, or until it ends. DELETION PROTECTION On by default: no app can be deleted from your iPhone, Arc Lock included. Switching it off waits only until your strict blocks reset or end. LOCK-IN Freeze every rule for 1 to 30 days, even between blocks: no loosening, no deleting rules, no deleting apps. Changes you queued before it wait until it ends. WEBSITES BY ADDRESS Type a site like youtube.com and it's blocked in Safari and every other browser, in schedules, daily limits, time-outs and Block now. APPLE'S OWN LOOK Native lists and a compact Liquid Glass tab bar: Home, Blocks and Settings. Names are optional: a block without one is shown by its first app. Five themes (Navy, Graphite, Forest, Plum and Paper), each with a matching app icon. The phone-and-lock mark in the app closes while something is blocked. PRIVATE BY DESIGN Arc Lock works through Apple's Screen Time. Apple keeps your activity on your iPhone; Arc Lock never learns which apps you use and sends nothing anywhere. No account, no analytics, no tracking.

Verdict
