Study Timer is a free, browser-based tool that lets you track how much time you spend studying, broken down by subject, and measure your progress against a daily goal. Add subjects like Math, Physics, or History, then start a timer for the one you are working on; the tool logs the elapsed minutes to that subject and rolls them into a running daily total displayed against the target you set.
It is built for students, exam candidates, and self-learners who want an honest record of focused study time rather than a guess. Because everything runs in your browser and stores data locally, you can close the tab and return later with your subject list, accumulated times, and daily goal still in place.
The timer measures elapsed real time using your device clock. When you press Start, it records a timestamp and updates the display roughly every second; when you Stop or Pause, it adds the difference to that subject's stored total. Each subject keeps its own cumulative counter, and the daily total is simply the sum of all subject counters for the current calendar day.
Progress toward your goal is a straightforward ratio: percent complete equals total minutes studied divided by the goal in minutes, multiplied by 100. For example, 90 minutes logged against a 240-minute goal shows 37.5 percent complete with 150 minutes remaining. At midnight (or when a new day begins), the daily total resets to zero while your goal and subject list carry over, so each day starts fresh.
The approach pairs naturally with focused-work techniques such as the Pomodoro method, where you study in 25-minute blocks separated by short breaks. You can simply start the timer at the beginning of a block and pause it during breaks so only genuine focused time is counted.
Yes, it is completely free with no sign-up required. Your subjects, times, and goals are stored locally in your own browser and are never uploaded to a server, so your study data stays on your device.
The timer itself stops when the tab is closed because it relies on the page being open. However, any time already logged before you left is saved, so your subject totals and daily progress are preserved when you return.
Yes. Because the tool uses local browser storage, clearing site data or cookies, or using private/incognito mode, can erase your saved subjects and recorded times. Use a normal browser window if you want your history to persist.
Yes. You can add as many subjects as you like and switch between them. Only one timer runs at a time, so stop the current subject before starting another to keep each subject's minutes accurate.
The daily total is the sum of the time logged across all your subjects for the current day. It is compared to your goal to produce the progress percentage and the minutes remaining.
Yes, the daily study total resets to zero at the start of each new day, while your goal setting and your list of subjects remain in place so you do not have to set them up again.
Absolutely. It works well for logging study sessions during exam preparation, and you can start it at the beginning of each Pomodoro focus block and pause during breaks so only actual study time is counted.
