Take your life back. The average person spends years of their remaining life staring at a screen. Perfect Lock shows you that numberβ€”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 locksβ€”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 tomorrowβ€”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 automaticallyβ€”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 timeβ€”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.

Cat's Study is a study timer where you focus alongside a cat. Start a task and the cat in the room opens its book too. It rests when you rest and dozes off when you're done. Homework, exams, deep work or reading: it all feels a little less lonely with company. FOCUS TIMER - Stopwatch or Pomodoro, with focus and break lengths set to the minute. - Get notified when it's time to focus or take a break. - Leave the screen alone while you focus and the room dims, with only the timer showing. Handy on a desk stand. TASK PLANNER - Tap β–Ά next to any of today's tasks to start right away. - Sort tasks into categories like Study or Work, and set daily ones to repeat. - Can't decide? Tap "Just start" and the cat comes up with a task for you. STUDY TRACKER - Daily, weekly and monthly focus time, broken down by category. - Focus 5+ minutes in one go each day to build a streak. - Share your records as an image. ROOM AND SOUNDS - Play rain sounds, thunder, library ambience or lofi music on the turntable, even with the screen off. - Ten room themes, including CafΓ© in the Rain, Cherry Blossom Study and Spaceship Study. - Earn coins from check-ins, focus sessions and streaks to dress up your cat and its room. FRIENDS AND CREWS - Visit a friend's room and see how long they've focused today. - Start a crew and everyone's cats gather in one room, showing who's focusing now and this week's check-ins.
