About Perfect Lock: Screen Time
Take your life back. The average person spends years of their remaining life staring at a screen. Perfect Lock shows you that number—and gives you the tools to shrink it. Most screen time apps are easy to ignore. Hit the limit, tap "ignore," extend the timer, and you're right back where you started. Perfect Lock is different. When you hit your limit, the app locks—and it stays locked. No loopholes When you reach your daily limit, that app is blocked for the rest of the day. You can't sneak back in by changing settings, deleting the limit, or turning the feature off. Try to edit it and you'll see "Can't change this today." Limits reset tomorrow—not the moment they get inconvenient. That's discipline that actually works. See the real cost Enter your age and daily usage, and Perfect Lock predicts how many years of your life you'll spend in front of a screen. For most of us, that's the wake-up call we needed. Powerful app limits Pick the apps that drain your time and set a daily cap. Go over it and the app locks automatically—even with Perfect Lock closed. It uses Apple's Screen Time framework to enforce limits reliably in the background. Focus Mode Start a focus session and every app goes dark until the timer ends. Only by finishing the session do you truly reclaim that time—no shortcuts, no quitting early without giving up the reward. Track the time you reclaim - Build a streak for every day you stay under your limits - Watch your total reclaimed time grow - See your last 7 days at a glance Time is the one thing you can't buy back. Perfect Lock helps you stop wasting it. Free and Pro Perfect Lock is free to limit one app. Upgrade to Pro to lock unlimited apps and categories at once. Pro is an auto-renewing subscription. Payment is charged to your Apple Account. It renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your account settings.
