Your study hours and your sleep are too important to leave to willpower. DrillLock locks the apps that eat them, and nothing opens again until you solve a math problem. You choose the apps that pull you away, and the hours they stay shut. Reach for one anyway and the math is waiting. Your hand stops, and the moment passes. IF THIS SOUNDS LIKE YOU • You sit down to study, open one app for a second, and the next hour is gone • You get into bed on time and you're still awake at 1 a.m., scrolling • You have a deadline this week and keep drifting away from the work • You're studying for an exam, a license, or a degree while working full time • You've tried Screen Time and found it far too easy to tap right past WHAT YOU CAN DO • Start focusing right now (Instant) Choose 15 minutes, 30 minutes, or an hour, and the noisy apps are out of reach for exactly that long. Made for the moment you finally sit down. • Decide once when the phone goes down (Schedule) Set the days and the time windows a single time. Your study block and your bedtime then hold on their own, so you're not renegotiating with yourself at midnight. • Call it a day once you've had enough (Time Limit) Give the apps that eat your evenings a daily allowance. The moment you pass it, they close for the rest of the day and the evening comes back to you. • One question stands between you and the app (Math Challenge) Nothing opens until you solve a math problem and get it right. It's a small enough step to clear when you truly need the app, and just enough friction that most of the time you set the phone down instead. • Ten minutes, then it closes itself (Temporary Unlock) Answer the challenge correctly and the app opens for ten minutes. After that it locks again by itself, with no timer to watch, and one tap re-locks it early when you're done sooner. GOOD TO KNOW • DrillLock needs Screen Time permission to lock and release apps • Phone and other essential apps are never locked, so you can always reach help in an emergency • Locking runs on Apple's Screen Time system, so iOS decides part of how a blocked app looks and behaves • Every locking decision is made on your iPhone. DrillLock does not send your browsing history or the names of the apps you restrict. DrillLock collects anonymous usage data to improve the app. PRO • Keep several rules running at the same time • Allowlist mode: block everything except the handful of apps you name • Set your own daily cap on temporary unlocks, so one rough evening can't become ten unlocks • Hard challenges, with your own choice of digit count and number of questions PRO is an auto-renewing subscription, monthly or yearly. You can cancel anytime in your Apple Account settings. Deciding once is easier than deciding fifty times a day. Set the rule tonight, and take back the hours that were quietly going missing.
