Time 30 minutes of Mathematics in the morning and save it, then 15 minutes in the evening and save that too. The subject totals show: Mathematics, 45 min in 2 sessions, and today's bar in the 7-day chart stands at 45 min.
- Sessions are stored only in this browser's local storage, dated by your device's local date. Export the log as JSON if you want a copy elsewhere.
- The timer measures elapsed real time while it runs; if you leave it running through a break, use Pause, or the break counts as study time.
- Sessions are filed under the date on which you save them, so a session saved after midnight counts toward the new day.
- The 7-day chart scales to your biggest day in that week, and each bar is labeled with its exact total, so small days are not exaggerated.
Yes. It is based on the clock, not on counting screen updates, so time in another tab or with the screen off still counts correctly while it is running.
About this tool
The Study Timer with Subject Log times your study sessions and files them under a subject, building up totals per subject and a seven-day chart. It is a simple, honest record of time actually studied: start the timer when you begin, pause for breaks, and save the session when you finish.
