About this app

QuantumBlock is a powerful App Blocker for Android that helps you block distracting apps and websites, reduce screen time, and regain control over your focus. Built for people who want real discipline instead of gentle reminders, QuantumBlock is a productivity app designed for serious focus.

In a world full of digital distractions, concentration becomes a superpower. This app blocker helps you use your smartphone more intentionally — whether for work, studying, or a complete digital detox.

🔥 LESS DISTRACTION. MORE PRODUCTIVITY.

Block distracting apps like social media, YouTube, or news apps with just a few taps. QuantumBlock stops mindless scrolling before it starts and helps you reduce screen time effectively.

🧠 SMART BLOCKING MODES — REAL CONTROL, NO GIMMICKS

— Instant Block
Immediately block selected apps and websites. A hard stop when distractions are not an option.

— Delay Mode
Add a short, intentional pause before an app opens. Interrupt automatic behavior and break the impulse that leads to endless scrolling.

— Reflection Check
Get mindful prompts that encourage you to pause and reflect on your intention before opening an app. Stop impulsive phone usage by making a conscious decision every time.

📁 GROUPS & SCHEDULES — FLEXIBLE SCREEN TIME CONTROL

Create custom blocking profiles for work, study, sleep, or free time. Schedule your app blocker by day and time so distractions stay blocked exactly when it matters. Manage your screen time automatically without constantly adjusting settings.

🔒 UNBREAKABLE MODE — STRICT APP BLOCK

When your focus is non-negotiable. Once activated, Unbreakable Mode cannot be disabled until the timer expires — not even by restarting your device. This strict app blocker is built for deep work, exams, and extreme digital detox.
