Block apps cold turkey with app lock and screen time control. Stay focused for study, work, bedtime, digital detox, dopamine detox, and phone addiction recovery.
Core Time is a strict app blocker and screen time app lock for people who need more than a gentle reminder. Block apps cold turkey, protect your focus, and stop losing hours to social media, dopamine loops, and phone addiction.
If Screen Time limits are too easy to ignore, Core Time gives you a harder reset. Choose the apps and websites that pull you away from what matters, set your lock duration or schedule, and let Core Time enforce the boundary until time is up.
▶ STRICT APP BLOCKER
Select distracting apps, set a timer, and tap Lock Now. Instagram, TikTok, YouTube, X, Reddit, games, and other dopamine traps stay blocked while your lock is active.
▶ SCREEN TIME APP LOCK
Use Core Time as a stronger screen time blocker when default limits are not enough. Create hard app limits for study, deep work, bedtime, weekends, or any moment when one more scroll can ruin your day.
▶ COLD TURKEY FOCUS
No snooze. No soft warning. No willpower negotiation. Core Time is built for people who want a cold turkey app blocker that removes temptation instead of asking you to resist it.
▶ STUDY, EXAMS, AND DEEP WORK
Start a lock before homework, exam prep, reading, writing, coding, or meetings. Keep your phone nearby without letting social media or games steal your focus.
▶ DOPAMINE DETOX AND DIGITAL DETOX
Trying to break a scrolling habit? Use Core Time to block the apps that trigger quick dopamine hits and build a calmer digital routine. It is useful for a daily digital detox, a weekend reset, or a longer phone addiction recovery plan.
▶ AUTOMATIC SCHEDULES
Set recurring locks for school hours, work blocks, family time, or sleep. Core Time can activate on your schedule so you do not need to decide again every day.
▶ ADHD-FRIENDLY FOCUS SUPPORT
When impulse control is hard, a reminder is not enough. Core Time helps by removing the option to open the apps you already decided to avoid.
▶ NO WAY OUT DURING A LOCK
During an active lock, selected apps and websites show a shield screen. Core Time uses Apple's Screen Time API and Family Controls framework so blocking runs on your device and stays private.
▶ ONE-TAP RECOVERY
If something goes wrong, use Fix Now in Settings to reset Core Time to a clean state quickly.
▶ RECOMMENDED FOR
• Students preparing for exams or homework
• Professionals protecting deep work blocks
• People with ADHD who need stronger focus boundaries
• Anyone reducing phone addiction, doomscrolling, or social media overuse
• Night owls who want to stop scrolling before bed
• Parents who want a clear app blocking routine on their own device
Core Time is not another reminder app. It is a strict app blocker, screen time blocker, app lock, focus timer, and digital detox tool for people who want their time back.
Take back control of your phone. Download Core Time and start your next focus block today.
▶ USE CASES THAT MATCH REAL LIFE
Use Core Time before a study session, during exam prep, while writing, when coding, during meetings, at the gym, or before sleep. If you keep opening the same apps without thinking, create a lock before the habit starts.
▶ WHY IT HELPS
Core Time turns a vague intention into a real boundary. Instead of checking your phone, feeling guilty, and trying again tomorrow, you make one decision up front and let the app enforce it.
▶ BUILT FOR REPEAT ROUTINES
The best results come from repeated locks: weekday work blocks, daily study sessions, lunch breaks without scrolling, and bedtime screen time limits. Start small, then make your focus routine automatic.
▶ SCREEN TIME CONTROL AND APP DETOX
Use Core Time as screen time control when you need cold turkey blocking, app detox, a dopamine detox app, or a phone detox app. It works as a blocker for apps that interrupt study, deep work, sleep, and real life.
