Decision Quality Drop

After 6 hours of cognitive work, the brain accumulates neurotoxic glutamate, and decision quality drops by ~10% — but you don't notice it subjectively.

Wiehler et al., Current Biology, 2022 — Paris Brain Institute

5.6 h

Hours Lost Per Week

Fatigued workers lose 5.6 hours of productivity per week — and 84% of losses come not from absenteeism, but from reduced efficiency right at the desk.

Ricci et al., JOEM, 2007 — sample of 28,902 workers

×5.6

Diagnostic Errors

Fatigued professionals make 5.6× more serious diagnostic errors. 17 hours without sleep = cognitive level of alcohol intoxication.

Blind to Own Fatigue

496,260 measurements from 12,645 workers showed: the correlation between self-assessed fatigue and actual state is virtually zero (r = −0.03).

Pomodoro Reinvented

Nintendo-style hearts meet productivity. Your 8-hour workday becomes 8 hearts. Deplete them during work, restore them during breaks.

8 hearts = 8 hours

Deplete during work

Restore during breaks

Eight hearts. Eight ways to win.

Each heart represents ~60 minutes of productive work. Start your day with full energy and track depletion in real-time.

Quick-Switch Presets

Classic (25-5), Extended (45-15), Sprint (15-3). Choose your rhythm, we handle the rest.

Hearts Restore During Rest

Breaks aren't interruptions—they're power-ups. Watch your hearts refill while you recharge.

AI Watches, You Just Work

Camera detects your face — timer starts. Step away — it pauses. AI tracks fatigue, blink rate, and focus so you take breaks before burnout, not after.

How does Focus24 analyze my state?

Focus24 uses your device's camera and a neural network to analyze facial expressions, head position, blink frequency, and even heart rate (via rPPG technology). Based on this data, the system determines alertness, focus, fatigue, and stress levels in real-time.

Is my data sent to a server?

No. All analysis and data storage happens entirely locally in your browser. Video stream is not recorded or transmitted. Data never leaves your device.

Which browsers are supported?

Focus24 works in modern browsers: Chrome, Firefox, Safari, and Edge. For best performance, we recommend Chrome or Firefox. Mobile browsers on iOS and Android are also supported.

Does Focus24 work offline?

Yes! Focus24 is a PWA (Progressive Web App). After the first visit, the app is cached and works without internet. You can install it on your desktop like a regular app.

How much storage do the data use?

Focus24 uses IndexedDB to store up to 100 sessions and 100,000 factor records. This takes about 10-50 MB depending on usage intensity. Old data is automatically deleted.

Can I export my data?

Yes, you can export all data in JSON format. Export is available in the Statistics section. Data is encrypted for secure storage and transfer between devices.

How do I cancel my subscription?

You can cancel your subscription at any time from the settings. After cancellation, access remains until the end of the paid period. Without an active subscription, the app continues to work in basic mode.

Do I need a good camera?

A regular webcam or laptop camera is sufficient. The main thing is good lighting on your face. The system adapts to different conditions and automatically calibrates on first launch.

Is there a task time tracker?

Yes! Focus24 includes a full task time tracker. Create tasks, track time, and take a mini-quiz after each task. The system saves metric dynamics during the task — you'll see how focus and fatigue changed.

Where is my data stored?

All data is stored in your browser's IndexedDB — a local storage that doesn't transmit data to the internet. You can export and delete your data at any time.
