Key takeaways:
A study hours tracker logs how much time you actually spend studying, by subject, so the honest total replaces a guess. Most people overestimate how much they study and underestimate how unevenly it's spread across subjects — a running log with daily, weekly and monthly totals fixes both at once.
Log with start and end times for accuracy, or enter total minutes directly when that's faster — both feed the same totals and chart.
A study session planner tells you what you intended to do; a study hours log tells you what actually happened, in real minutes. Together they show the gap between planned and actual — and the hours log alone is often the more sobering number, since a "quick review" reliably runs longer or shorter than it feels at the time.
Pair this with the Study Session Planner to plan sessions in advance, and the Exam Score Tracker to see whether more logged hours in a subject actually shows up in results.
How is total study time calculated?
End time minus start time, minus any break minutes you enter. A 2pm-4pm session with a 15-minute break logs as 1 hour 45 minutes.
Can I track study time by subject?
Yes — every session is logged with a subject, and the summary and history show totals so you can see where your study time is actually going.
What does the chart show?
Total study minutes per day over your recent history, so you can see consistency at a glance rather than reading through a long list of sessions.
Where is my study log stored?
Entirely in this browser's local storage, on this device. Nothing is uploaded. Export a CSV as a backup or to review in a spreadsheet.
Can I log a session without an end time?
You can enter total minutes directly instead of a start and end time, if that's easier — either method logs the same way.
Can I delete a session?
Yes — delete any row with the ✕ button. There's no in-place edit — remove it and log it again with corrected times.
