MassBlocker: Focus App Blocker

MassBlocker blocks distracting apps until you do something real to unlock them.

Use it for a dopamine detox, to cut screen time, to break the doom-scroll and get into focus mode. It's the software answer to a Brick — the same physical friction, without buying the hardware.

Every other app blocker has a snooze button, and you always tap it. MassBlocker doesn't. To open a blocked app you have to get up and scan a QR code you placed somewhere out of reach — after a cooldown you can't skip.

HOW IT WORKS

Pick the apps that distract you
Place an unlock QR somewhere inconvenient (another room, the fridge, the gym)
To open a blocked app, go scan it — then a short window, then a cooldown
Want it stricter? Add a PIN and hand it to someone you trust

WHY IT WORKS
The unlock is a physical action, not a timer you wait out or a toggle you switch off. The friction is the point.

ACCESSIBILITY SERVICE
MassBlocker uses the Android Accessibility API to deliver its core feature: blocking apps. The accessibility service detects when an app on your blocklist comes to the foreground and immediately shows the lock screen. Without this permission, MassBlocker cannot tell which app you just opened, and blocking cannot work.

MassBlocker uses the accessibility service only to read the package name of the app currently in the foreground so it knows whether to block it. It does not read the content of your screen, capture text you type, or monitor what you do inside other apps. Accessibility data stays on your device and is never collected, shared, or sold.

The only change from what's live: the new short line up top, and the second paragraph ("Use it for a dopamine detox...") which banks detox, screen time, focus mode, and Brick as search terms. Everything else is your existing copy untouched.
