Twilock: Screen Time Blocker
Sleep Better, Stop Scrolling
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
The two hours before sleep and the first after waking are where the scroll lives. Twilock shields your chosen apps for exactly those windows, then gets out of the way.
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.

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.
