Your phone steals 5+ hours of your day. Core Time locks it down — cold turkey.
Struggling with phone addiction? Spending hours on social media instead of focusing on what matters? Core Time forces you to go cold turkey on distracting apps — no compromises, no exceptions.
Most screen time apps nudge you with gentle reminders, hoping you'll put the phone down on your own. That doesn't work. Core Time is a strict app blocker that enforces a hard lock on the apps and websites you choose. Once you tap Lock Now, there is no bypass, no snooze, no workaround. Blocked apps stay blocked until time's up.
▶ INSTANT APP BLOCKER
Set the timer. Select the apps you want to block. Tap Lock Now. Done in under 30 seconds. No complicated setup, no subscription wall before your first lock. Take back control of your screen time immediately.
▶ SCHEDULED LOCK — SET IT AND FORGET IT
Create recurring lock schedules for study blocks, deep work hours, or bedtime. Core Time activates automatically on your schedule — zero daily effort after setup.
▶ NO WAY OUT — THE STRICTEST BLOCK ON iOS
During a lock session, blocked apps display a shield screen. You cannot bypass it. You cannot delete the app to escape. You cannot change device time to cheat. No secret menu, no override code. This is the strictest app blocker on iOS — a true cold turkey blocker for breaking phone addiction.
▶ BLOCK SOCIAL MEDIA & DOPAMINE TRAPS
Instagram, TikTok, YouTube, X, Reddit, games — whatever drains your focus and feeds the dopamine cycle, Core Time blocks it. Stop doomscrolling. Start your dopamine detox today.
▶ ADHD-FRIENDLY FOCUS MODE
Designed for people with ADHD who need extra help staying on task. Core Time removes the temptation entirely — no willpower required. Pair it with the built-in focus timer to build productive habits.
▶ SCREEN TIME CONTROL
Set hard limits that actually stick. Unlike default screen time features that let you bypass with a single tap, Core Time enforces your limits with zero compromise.
▶ ONE-TAP RECOVERY
Something went wrong? Tap Fix Now in Settings and Core Time resets to a clean state instantly.
▶ RECOMMENDED FOR
• Students who lose study hours to social media
• Professionals who need distraction-free deep work blocks
• People with ADHD who struggle with impulse control and app overuse
• Parents who want to limit screen time with a blocker that can't be bypassed
• Anyone trying to break a phone addiction or start a digital detox
• Night owls who want to stop doomscrolling before bed
▶ WHY CORE TIME IS DIFFERENT
Other apps give you a warning and let you dismiss it. Core Time does not. Other apps let you extend your limit with a tap. Core Time does not. Other apps trust your willpower. Core Time replaces it.
▶ PRIVATE & SECURE
Core Time uses Apple's Screen Time API (Family Controls framework). All blocking runs entirely on your device. No accounts, no cloud sync, no tracking. Your data never leaves your phone.
Take back control of your time. Download Core Time and start your digital detox today.
