How to use a stopwatch to track study time
Key takeaways
- Start the stopwatch when you sit down to work and pause it whenever you take a break; only active time counts.
- Press Lap when you switch subject or task, and label each lap so you know where the time went.
- Full screen with hundredths hidden gives a calm display on a second screen or across a desk.
- Save the session on this device or download a CSV to keep a log over several weeks.
Why time study with a stopwatch instead of a countdown?
A countdown tells you when to stop. A stopwatch tells you how long you actually worked, which is useful when you want to see where an evening went, compare subjects, or check how long a type of task really takes you. If you prefer fixed blocks with an alarm, use our sister site Online Timer instead.
How do I set it up for a study session?
- Open the stopwatch and type a session name, such as "Tuesday evening" or "Exam week, day 3".
- Turn on Keep screen awake if the screen tends to dim while you read.
- Choose Open Full Screen (or F) and switch Show hundredths off for a quieter display.
- Press Start when you begin.
- Press Pause whenever you stand up, check your phone or take a break. Paused time is never counted.
How do I see time per subject?
Press Lap each time you switch. The lap that just ended is the time you spent on the last subject. Give it a label such as "Chemistry" or "Essay draft". After two or more laps the stopwatch shows the fastest, slowest and average lap, and the table lists each lap with the running total next to it.
A made-up example evening: Chemistry 42 minutes, Essay 55 minutes, Vocabulary 18 minutes. The total under the last split is 1 hour 55 minutes of active study, with breaks left out.
How do I keep a log over several days?
- Save session keeps the session on this device (pause first). Up to 20 sessions fit, so delete old ones when you have copied them elsewhere.
- Download CSV gives a file with every lap's label and time. Paste each day's file into one spreadsheet to see totals per subject over a week or a term.
- Copy results gives a one-line summary for a notes app or a study group chat.
Can a class or study group use it together?
Yes, on one shared screen. The classroom stopwatch hides hundredths by default and suits a projector. It times one session at a time, so it cannot track several students separately.
Questions
Does the stopwatch keep running if I switch to another tab? Yes. Time is worked out from the clock, so it is still right when you come back. If the computer goes to sleep, a notice tells you the time may be uncertain.
Is anything I type sent anywhere? No. Session names, labels and saved sessions stay in your browser on this device.
