Serious focus protection

A focus blocker that does not give up when you do.

Built for deep work, study sessions, and deadline weeks - with stronger friction than browser extensions, timers, and lightweight focus apps.

Failure modes

Focus tools fail when work starts feeling hard.

The dangerous moment is not when you plan your day. It is when the task becomes boring, ambiguous, or uncomfortable - and opening a distraction feels like relief.

You open YouTube for research.
You check Reddit for one answer.
You disable the extension because this task is an exception.
You move from phone to desktop or desktop to phone.
You lose an hour and tell yourself tomorrow will be different.

System layers

Deep work needs stronger boundaries than good intentions.

Protected focus sessions

Start a session where distracting apps and sites cannot be changed instantly.

Delayed rule changes

If you try to unblock something mid-session, the change waits until later.

Cross-device focus rules

Designed for Android + Windows so your phone cannot become the loophole.

Tamper history

Review when you tried to break your own focus rules.

Weak-point protection score

See whether alternate browsers, VPNs, or device settings are still loopholes.

Optional accountability mode

Let a cofounder, study partner, or friend approve high-risk changes.

Use cases

Built for the work blocks that actually matter.

Coding sprints

Keep GitHub and docs open, block YouTube, Reddit, X, and news.

Study sessions

Protect exam prep blocks from phone and browser distractions.

Writing days

Block research rabbit holes after your source list is set.

Deadline weeks

Lock down high-risk sites until the deadline is shipped.

Morning deep work

Protect the first 2-4 hours before the day fragments.

Flow

Set rules while rational. Enforce them when distracted.

Create a focus profile

Choose blocked apps, blocked sites, allowed tools, and session duration.

Start a protected session

During the session, changes are delayed or require accountability approval.

Continue working when impulse hits

The product does not negotiate instantly with the version of you looking for escape.

Review the session

See focus time, bypass attempts, and weak points.

Trust boundary

Stronger than a timer. More honest than unbreakable.

No blocker can honestly promise to be impossible to bypass on a device you fully control. AppBrake is designed to make bypassing slower, harder, and more visible - especially during the short impulse window where most relapses and distractions happen. AppBrake Focus is designed to make common workarounds slow enough that the urge usually passes before the block does.
