Frequently Asked Questions
Tracking How Long You Actually Study, By Subject
Most people underestimate how their study time is really split across subjects — a topic that feels like it got plenty of attention often turns out to have had less time than a subject that felt quick but dragged on. A study time tracker replaces that impression with an actual record: a live timer for each session, plus a running log broken down by subject.
Running the Timer
Enter a subject, set a daily goal in minutes, and start the timer. It runs continuously with pause and resume, and a progress bar fills as the current session moves toward your goal. It's worth being precise about what that bar actually measures: it tracks the current running session against your goal, not a cumulative total across every session you've logged that day. If you study 40 minutes, save the session, and start a fresh 40-minute session later, the bar resets and tracks that second session on its own rather than adding to the first.
Logging Past Sessions Manually
Not every study session happens with the timer running. The manual log lets you add a subject, duration, start time, and a 1-to-5 star rating for sessions you want on record after the fact — useful for backfilling a day you forgot to time, or for logging study done somewhere the tracker wasn't open.
Where the Subject Breakdown Actually Helps
The Stats view totals your minutes by subject and shows them as comparative bars against your highest-logged subject. This is where the tracker earns its keep beyond a simple stopwatch: it's the difference between feeling like you've been studying "a lot of everything" and seeing, in actual logged minutes, that one subject has quietly taken three times the time of another. That kind of imbalance is easy to miss without a record and obvious once one exists.
Where Your Data Lives
Sessions are saved in your browser's local storage, which means they persist if you close the tab and come back later on the same browser and device. They aren't sent to a server as part of this tool's implementation, but they also aren't backed up anywhere else — clearing your browser's site data, using a different browser, or switching devices will not carry your log over. If your study history matters long-term, it's worth periodically using the copy function to save a plain-text backup elsewhere.
Frequently Asked Questions
Does the daily goal track my total study time for the whole day?
No — the goal progress bar tracks only the currently running timer session against your set goal, not a sum of every session saved that day. If you want a full daily total, check the Stats tab after logging all your sessions for the day.
What's the minimum session length that can be saved?
Sessions need to run for at least 10 seconds before the Save Session button will log them — this prevents accidental taps from creating meaningless zero-length entries in your history.
Will I lose my study log if I switch to a different device?
Yes — since sessions are stored locally in your browser rather than on a server tied to an account, your log won't automatically appear on a different browser or device. Copy your log periodically if you want a backup you can move elsewhere.
What does the star rating on a session actually track?
It's a self-assessed quality rating you assign when logging a session — useful for noticing patterns later, like whether your highest-rated sessions tend to happen at a particular time of day or after a particular length of study.
Related Tools and Resources
A few related tools fit alongside a study routine in ways this tracker doesn't cover directly.
Use a Pomodoro Timer if you want structured focus-and-break intervals rather than an open-ended stopwatch.
Try an Exam Countdown to see exactly how many days remain before a test you're studying for.
A School Days Calculator is useful for a broader view of how many school days remain in your term or year.
Use a Focus Timer if you want to log distractions alongside your session, not just the time spent.
A Record Beats a Guess
It's easy to feel like study time is evenly spread across subjects when it usually isn't. A running log, even a simple one, turns that vague impression into an actual number you can act on — whether that means shifting more time toward a neglected subject or just confirming that your instinct about where the hours went was right all along.
