Real blocking.
Lock your desktop.
Do deep work.

FocusFlow kills blocked processes via Win32, locks your Windows desktop into a distraction-free kiosk with Focus Launcher, and enforces focus sessions with a PIN gate. No soft timers. No workarounds. Real enforcement.

Focus Launcher

Lock your entire desktop.
No escape without your PIN.

Focus Launcher is a CBT-inspired kiosk mode that replaces your Windows desktop with a distraction-free workspace the moment a session begins.

Crash-Safe Design

Four recovery mechanisms can restore your taskbar: at startup, during JVM shutdown, through a crash handler, and at the next Windows sign-in. Severe Windows or system failures can still affect recovery.

Safe Input Whitelist

A curated list of 55+ essential processes is protected, including keyboard drivers, touchpad software, audio, UAC, and accessibility tools. The list is intended to keep core input and system functions available.

Real Enforcement

Process killed. Firewall rule added.
Attempt logged.

Every enforcement action fires immediately using two independent detection methods — no grace period, no warning dialog, no snooze button.

Instant Detection via WinEventHook

A SetWinEventHook fires the moment any blocked app comes to the foreground. A 500ms polling loop catches anything the hook misses, including UWP apps.

Process Kill via Win32/JNA

ProcessHandle.destroyForcibly() is attempted first, followed by a taskkill /F /IM fallback. Windows permissions or protected processes may still prevent termination.

Windows Firewall Rules

Network blocking can add an outbound netsh advfirewall rule for the app. Administrator access is required to manage Windows Firewall rules.

Temptation Diary

Every blocked attempt is written to a local SQLite database. Charts show your distraction patterns over time so you can understand and change your habits.

Website Blocker

Blocks configured domains through the Windows hosts file without a browser extension. Administrator access is required; VPNs, Secure DNS, cached DNS, and existing connections can affect blocking.

Keyword Blocker

Block any window whose title contains a keyword — catch social media tabs, news sites, and chat apps without listing every domain.

Nuclear Mode

Maximum enforcement — blocks Task Manager, PowerShell, Run dialog, CMD, and 30+ other escape routes.

Block Schedules

Set recurring time windows when apps are automatically blocked — e.g. social media blocked 9am–5pm every weekday.

Daily Allowances

Give any app a daily time budget — e.g. 30 minutes of YouTube per day. When the budget runs out, it's blocked for the rest of the day.

Block Defense

Configure how hard it is to disable your own blocking rules mid-session. Make it easy, require a PIN, or lock it until the session ends.

Everything Else

A complete productivity system,
not just a timer.

Beyond blocking, FocusFlow gives you every tool you need to plan, track, and review your focused work.

Focus Sessions

Pomodoro or custom length sessions with a session PIN, break enforcer, and sound aversion tones that fire every time you try to open a blocked app.

Stats & Reports

Focus streaks, session history, temptation log charts, and a weekly focus report automatically delivered every Sunday via Windows notification.

Habit Tracker

Build daily habits with a 7-day streak grid. Habits linked to your focus sessions so you see what disciplines drive your most productive days.

Task Manager

Full task CRUD with priorities, due dates, recurring rules (daily / weekday / weekly / monthly), and Windows alarm notifications.

Daily Notes

A private daily journal linked to your session data. Plan your day before a session and review it after — all stored locally, never synced anywhere.

100% Private

No account. No internet required for the app. No analytics or tracking. Your tasks, notes, habits, and session history stay in a local SQLite database; optional anonymous crash diagnostics can be disabled in Settings.
