You open Instagram for one second. Twenty minutes later you're still there.

CogniFocus is a focus timer and app blocker that pushes back when your attention slips. Start a session and the Distraction Shield watches for every app you said you'd stop opening. The moment you switch, it blocks it. Then the Goblin reacts. Not a push notification. An actual reaction shaped by what you've been doing all session.

Annoyed if you keep slipping. Cheerful when you finish clean. Angry if you really push it.

It sounds small. It isn't.

HOW THE APP BLOCKER WORKS

CogniFocus monitors your active app during focus sessions using Android's Usage Access permission. Open a blocked app and the screen blocker kicks in immediately, before one quick check becomes a 30-minute scroll. Lockout countdowns get longer each time you try. You pick the apps to block, TikTok, Instagram, YouTube, Reddit, or anything else, and the Shield holds the line.

THE GOBLIN

Most focus apps ignore you the moment you drift. The Goblin doesn't. It tracks your distraction rate, recovery speed, and session momentum, then reacts at the moments that count: when you slip, when you recover, when your streak is at risk, when you finish a clean session. It builds context over time so reactions fit your actual week, not just a random trigger.

FOCUS SESSIONS

Set a custom or preset duration. Live countdown timer. Pause, resume, or adjust mid-session. Session quality scored automatically so you can see whether you're actually improving or just logging time.

MANUAL BLOCK (Pro)

Lock yourself out of distracting apps between sessions. Stronger than a screen time limit. Comes with a 4-second confirm countdown so you can't impulse-block something you need ten minutes later.

DND FOCUS MODE (Pro)

Silence all calls and notifications automatically when a session starts. Combine with the app blocker for a real distraction-free mode.

PLANNED SESSIONS (Pro)

Schedule focus blocks ahead of time. Reminders before they start. Completions and misses tracked so you can see your planning vs follow-through.

BEHAVIORAL STATS

Distraction patterns, recovery speed, and focus trends tracked across your history. The Goblin reads all of it. After a rough week it knows, and its tone shifts to match.

STREAKS AND FOCUS SHARDS

Daily streak tracking with streak shields so one bad day doesn't erase a long run. Earn Focus Shards for showing up consistently and leveling up over time.

CLOUD SYNC (Pro)

Stats, blocked apps, sessions, and progress backed up and restorable. Switch devices without losing your history.

WHO IT'S FOR

Students who lose study sessions to social media. Developers and remote workers who keep switching apps during deep work. Anyone who's tried screen time limits and found them too easy to override.

CogniFocus works differently from standard screen time or parental control apps because it reacts. A timer that ignores you when you break it teaches you nothing. A Goblin that gets genuinely annoyed is harder to ignore.

PLANS

Basic (Free): 3 blocked apps, sessions up to 90 minutes, Distraction Shield, core Goblin reactions.
