What is Timer
Timer (timer.moneycomon.com) is a collection of free web tools that help with everyday time management for studying, work, exercise, cooking, waking up, and more. You can use it right in your browser with no install or sign-up, and it is designed with a large time display and simple buttons so you can use it comfortably on desktop or mobile.
Tools we offer
- Pomodoro Timer — Automatically manages 25-minute focus and 5-minute break cycles and rings an alarm.
- Online Stopwatch — Measures elapsed time to 0.01 seconds and records lap times.
- Countdown Timer — Set hours, minutes, and seconds and get an alarm when it reaches zero.
- Online Alarm — Set a time and have an alarm sound ring at that moment.
Operating principles (E-E-A-T)
- Experience — The tools are built to reflect the time units and flows people actually use in real studying, work, and exercise.
- Expertise — We summarize the principles of proven time management methods such as the Pomodoro Technique in our guides.
- Authoritativeness — We clearly explain how each tool works and its limitations without hiding anything.
- Trustworthiness — We do not collect or store inputs, and we clearly state that the alarms and time measurement are supplementary aids.
How it works
All timers and alarms use JavaScript's setInterval and the browser's built-in Web Audio to generate and play alarm sounds with no separate file download. Time measurement is based on the device's system clock and works most accurately when the browser tab is active.
Notes on accuracy
Web browsers may throttle timers in background tabs to save power, so switching to another tab or app can somewhat delay the alarm. Also, alarm sound playback requires the user to press a button at least once due to browser autoplay policies. The timers and alarms on this site are supplementary reference tools, so for alarms you absolutely cannot miss, please use them together with your phone's built-in alarm app.
