Productivity tools help you work smarter, measure your performance, and maintain focus throughout the workday. Whether you are a developer tracking your typing speed, a student using the Pomodoro technique to stay on task, or a remote worker needing ambient sound to block distractions — these browser-based utilities run entirely without installation or login. The Pomodoro Timer implements the scientifically-backed 25/5 work-break cycle with audible alerts and session tracking. The Typing Speed Test measures your words per minute and accuracy against standardized passages, tracking your personal best over time. The White Noise Generator uses the Web Audio API to synthesize white, pink, and brown noise — proven to mask distracting office sounds and improve cognitive focus. All tools save your preferences locally in your browser so your settings persist between sessions.

Frequently Asked Questions

Does the Pomodoro Timer send notifications when time is up?

Yes. The timer uses the Web Notifications API to send browser notifications when a session ends, even if the tab is in the background. You will be prompted to allow notifications on first use. Additionally, a short audio tone plays using the Web Audio API — no external sound files are required.

Is my typing speed data stored anywhere?

No. All typing speed data — including your WPM scores, accuracy percentages, and personal best — is stored only in your browser's localStorage. No data is transmitted to any server. Clearing your browser data will reset your history.

What is the difference between white, pink, and brown noise?

White noise contains equal energy at all frequencies and sounds like static — ideal for masking sudden sharp sounds. Pink noise has more energy in lower frequencies, sounds like a steady rain or waterfall, and is often preferred for sleep and concentration. Brown noise (also called red noise) has even more bass energy and sounds like a deep rumble or ocean waves — many people find it the most soothing of the three.

What is the Pomodoro Technique?

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. It divides work into 25-minute focused intervals (called "pomodoros") separated by 5-minute short breaks. After four pomodoros, you take a longer break of 15–30 minutes. The technique reduces mental fatigue, improves focus, and helps overcome procrastination by making large tasks feel manageable.

What is a good typing speed in WPM?

Average typing speed for adults is 40–50 WPM. Proficient typists reach 60–80 WPM. Professional typists and skilled developers often type at 80–100 WPM. Speed above 100 WPM is considered fast. More important than raw speed is accuracy — a 95%+ accuracy rate ensures you spend less time on corrections. The Typing Speed Test measures both metrics and shows your net WPM (adjusted for errors).
