About

Timer, Alarm ,Countdown and Stopwatch for Google Chrome™

Are you tired of juggling multiple tabs, phone apps, and mental notes just to keep track of time?

Introduce efficiency into your browsing routine with Timer, Alarm, Countdown and Stopwatch for Google Chrome™. This single, lightweight extension replaces scattered tools with a robust, unified hub for all your time management needs.

Whether you are implementing the Pomodoro technique for deep work, tracking freelance hours with precision, cooking a meal while browsing, or ensuring you never miss an important online meeting, this extension is designed to keep you on track without disrupting your workflow.

🌟 KEY FEATURES AT A GLANCE
This isn't just a simple clock; it’s a comprehensive time toolkit built for the modern web user.

✅ Four Essential Modes: Switch instantly between Timer, Stopwatch, Countdown, and Alarm tabs in one consolidated interface.

✅ Reliable Background Operation: Unlike many other extensions, this tool uses advanced Chrome APIs (Alarms and Offscreen Documents) to ensure your timers keep running and your alarms sound even if you close the extension popup window.

✅ Audio & Visual Alerts: Never miss a moment. You get a clear audio signal (alarm.mp3) and a system notification banner when time is up.

✅ Sleek Dark Mode UI: Designed with a modern "Bold Modern Palette" (dark slate and indigo accent colors), it is easy on the eyes and looks professional in any browser setup.

✅ Zero Data Collection: Your privacy matters. This extension operates entirely locally within your browser and does not track your activity.

🔎 DETAILED FEATURE BREAKDOWN
1️⃣ The Productivity Timer
Perfect for focus sessions, interval training, or quick reminders.

Quick Presets: Launch a timer instantly with one-click buttons for popular durations: 5 Minutes (quick break), 10 Minutes, and 25 Minutes (ideal for Pomodoro sessions).

Custom Duration: Need a specific time? Easily input custom Hours, Minutes, and Seconds via large, easy-to-read fields.

Simple Controls: Start, Pause, and Reset with ease.

2️⃣ High-Precision Stopwatch
Accurate time tracking for professionals, athletes, and anyone who needs to measure duration.

Centisecond Precision: The display shows time down to the hundredth of a second (00:00:00.00) for maximum accuracy.

Lap Functionality: Record splits without stopping the main timer. A scrollable history lists every lap you record, perfect for tracking progress over repeated tasks.

Smooth Animation: Engineered for performance, ensuring the numbers update smoothly without lagging your browser.

3️⃣ The Countdown
Set it and forget it until the deadline arrives.

Deadline Tracking: Similar to the timer but focused on counting down to zero from a specific duration.

Clear Completion: Triggers a distinct "Countdown Complete" notification so you know exactly when your allotted time has expired.

4️⃣ The Daily Alarm
Your browser-based wake-up call or meeting reminder.

Set Specific Times: Instead of a duration, set a specific time of day (e.g., "14:30:00") for the alarm to trigger.

Active Status: The main interface clearly shows the currently set alarm time so you can verify it at a glance.

Easy Cancellation: Changed your plans? Cancel an active alarm with a single click before it rings.

💡 PERFECT USE CASES
Who is this Chrome extension for?

👨‍💻 Remote Workers & Freelancers: Use the Timer for time-blocking tasks to increase focus, or use the Stopwatch to accurately track billable hours for clients without leaving the browser.

🎓 Students & Researchers: Utilize the 25-minute preset for disciplined study sessions and breaks. Use the countdown for timed quizzes or practice exams.

🍳 Home Cooks & Bakers: Set multiple reminders for different dishes. Because it runs in the background, you can look up recipes in other tabs without losing your oven timer.

📅 Professionals with Tight Schedules: Set an Alarm for 5 minutes before your next Zoom or Teams call to ensure you are never late again.

🏋️‍♀️ Fitness Enthusiasts: Use the stopwatch with lap functionality to track intervals during web-based workout routines.

WHY CHOOSE US?
We built this extension to solve a common frustration: browser timers that stop working when you click away. By leveraging robust background service workers and offscreen audio playback, we ensure reliability. It’s the set-it-and-forget-it solution chrome users deserve.

Boost your productivity and take control of your time today.
