The app blocker you can’t talk your way out of.
Every other blocker has a snooze button — and you always tap it. MassBlocker makes unlocking cost something real: scan a code you hid, tap a tag by the door, or keep your phone on the charger. The friction is the point.

MassBlocker is an Android app blocker that locks your chosen apps behind real friction — a QR scan, an NFC tap, or staying plugged in — plus a cooldown you set. No snooze, no toggle. The block actually holds.
Why screen-time limits never hold
Screen-time limiters fail because they run on the honor system. A timer you can extend. An “I’m done” button. A limit you set and quietly raise at 11pm. Willpower at the exact moment willpower is gone. Nothing actually stands between you and the app.
How it works
Pick the apps
The ones that eat your day.
Choose how you unlock
And make it inconvenient on purpose.
Wait out a cooldown you set
Or a schedule you set in advance.
That's it
When the urge hits, the app is just… not there yet.
The unlock is a physical action, not a toggle. It’s the app-blocker version of leaving your phone in another room.

Unlock your way
QR code
Scan one you printed and hid — bookshelf, fridge, gym bag. Or bring your own: turn any sticker or card into your key.
3-word code
No camera? Read three words off the printout and type them.
Charging cable
Apps open only while the phone is plugged in. Want to scroll? You're tethered to the wall.
NFC tag
Tap a sticker you placed somewhere annoying to unlock.

Blocks that run themselves
Schedules
A bedtime (21:00–07:00), study hours, anything recurring. Apps lock on their own; you never have to remember.
Profiles
Different sets of apps with their own rules. A strict “Bedtime”, a charging-only “Focus”, a weekday “Work”. Run as many as you like.

For the strong-willed and the weak-willed
Strict mode with a PIN
Hand it to someone you trust; only they can open things.
Uninstall protection
During a lock, the app can’t be deleted without the PIN. No escape hatch.

Strict mode is a strong deterrent, not an unbreakable jail — on stock Android a determined user can disable the service.
Share it
Family — one plan covers up to 5 people, with a master unlock code you keep and per-person controls.
Why it works — and why it’s different
Hardware “focus phones” give you an earn-your-way-back ritual, and a physical dongle to carry and lose. MassBlocker gives you the same friction with a code you already have — the Brick, without the Brick.
And unlike the timer-and-toggle blockers, nothing here can be snoozed or switched off in a weak moment — the block is a real-world action, not a button.

Can I just uninstall it?
In strict mode, no — uninstalling is blocked behind the PIN. Otherwise yes; it's a tool, not a prison.
Does it read my screen?
No. It uses Android's accessibility service only to see which app is in the foreground so it knows whether to block it. It never reads screen content, keystrokes, or what you do inside other apps, and nothing is sold or shared.
What stops me unlocking instantly?
A cooldown you set runs before the unlock is accepted, and you decide where the QR or tag lives — distance is the point. Strict mode adds a PIN so you can't bypass it alone.
What if I lose the QR?
Generate a new one any time, or use the 3-word code.
How is this different from Android Digital Wellbeing?
Built-in Wellbeing gives a timer you extend with one tap. MassBlocker uses an enforced cooldown plus a physical unlock. The friction is the feature.
iPhone?
Android only for now.
How do I pay?
Web checkout via Stripe, not in-app. Free needs no account.
