Focus where it matters. DutyLock blocks your most distracting apps the moment you walk into a place you've chosen. Walk out, they unlock. No willpower required. WALK IN. APPS LOCK. Pick the places. Pick the apps. DutyLock takes the decision off your hands. WHO USES DUTYLOCK Knowledge workers who can't afford a five-minute Instagram detour every hour. They set a lock at their desk and the phone goes quiet while they're there. People reclaiming their evenings. The phone goes down when they sit at the dinner table. Their partner gets them back. Their kids notice. The doomscroll quitters. They turn bedtime into a zone. The TikTok rabbit hole stops existing between 9pm and 7am. People trying to actually sleep. The phone locks itself when they get into bed instead of becoming the thing that keeps them awake until 2am. Gym-goers who want their session. They walk in, the apps lock, the workout is the workout. People who want to read on the train again, or just sit and think on the bus. The commute becomes a real commute, not another scroll session. Movie-goers who go to watch the movie. Couples who want dinner without a phone face-down on the table. People on a date who would like to be on it. Students who turn the library into a study zone and don't see Reddit until they walk back outside. Managers and operators who run shifts on a warehouse floor, in a store, or anywhere phones are supposed to stay in pockets. DutyLock locks the named apps inside the named zones and time windows. Every lock event is logged. No quiet workaround. No restart trick. No Settings toggle that turns it off without somebody knowing. YOUR HISTORY. ON THE RECORD. Every lock and unlock is logged. Export it as a clean report whenever you want proof of where the time went. STAYS ON YOUR IPHONE No account. No cloud. No analytics. DutyLock is for people who want to focus and have tried everything else.

You do not decide to scroll until 1am. It just happens. Twilock shields the apps that pull you in during the two windows that cost you most: the hours right before sleep, and the ones right after waking. Pick the apps. Pick your window. Twilock handles the rest, so there is no willpower contest and no bargaining with yourself at 11pm. HOW IT WORKS 1. Choose the apps that pull you in most. 2. Set your Night window, up to two hours, over the stretch where your nights actually go sideways. 3. When the window opens, those apps are shielded. Nothing to decide, nothing to resist. WHY IT FEELS DIFFERENT Most blockers go all or nothing and you end up disabling them by lunchtime. Twilock never takes your whole day. It covers up to two hours at night, plus up to two in the morning on Pro, because those are the hours that decide how you sleep and how you start. BUILD A STREAK YOU ACTUALLY WANT Every protected night grows your streak on a calendar that is satisfying to keep green, and earns you badges along the way. An attempt the shield caught still counts as a win, not a slip. Reach a 7 day streak and you earn a free Streak Freeze to cover a slip later, with two more waiting at 30 and 90 days. You also get one Snooze Token every week for the nights you genuinely need your phone. All free, no purchase, ever. SEE THE PAYOFF Watch the hours you have reclaimed add up, glance back at your streak history, and check in on how your sleep and energy are trending. All private, all on your device. STAY ACCOUNTABLE WITH FRIENDS Share your invite code, connect with friends, and keep each other honest on a shared streak leaderboard. Free for everyone. A little gentle competition helps more than it should. PRIVATE BY DESIGN Your Screen Time and app usage data never leave your device. We cannot see which apps you picked or how long you use them. No ads, no data selling, ever. FREE TO START, PRO WHEN YOU'RE READY Free, always: your Night window, streaks, badges, Streak Freeze, the weekly Snooze Token, friends and the leaderboard, and your reclaimed hours count. Every new install also includes three Strict Night windows, so you can experience the strongest lock before deciding whether to upgrade. Pro adds: a Morning window, continued Strict Mode after those three included nights, Streak Repair, and deeper insights. Take back your nights and mornings, one calm streak at a time. Twilock Pro is offered as a monthly or annual auto renewing subscription, or as a one time Lifetime purchase. Prices are shown in the app before you buy. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.
