How to track study time by subject, and actually read the numbers
Students who track their study time consistently say the same thing: "seeing the number made me sit at the desk one minute longer". The number itself is the motivation. But a number you cannot trust motivates nothing, so the setup matters. Here is the setup that works, from a lot of reviews and our own use.
1. Subjects, not tasks
Make one subject per exam area: Math, English, History. Not "Chapter 7" and not "review". Subjects are stable across months, which is what makes the weekly chart comparable. Five to eight subjects is the sweet spot; more than that and you stop switching properly.
2. Only pure study time counts
Korean students call it soongong, "pure study": the clock runs only while you are actually working. Stop it when you get up, when you check your phone, when you look something up for more than a minute. A good app then treats the gap between two sessions as a break and shows it separately, so your day reads as "4h 10m study, 55m breaks" instead of a vague six hours.
3. Set the day boundary for your schedule
If you study until 2 AM, a midnight reset splits one evening across two days and makes both look weak. Pick a day-start time that matches when you actually sleep, 4 or 5 AM for night owls, and keep it. Records should also survive crossing that line; a session from 23:40 to 00:30 is one session.
4. Fix records the same day
You will forget to press start. Add the session by typing the start and end time while you still remember, and mark it so you know it was manual. Do not let a missed hour turn into "the numbers are wrong anyway".
5. Read three numbers a week
- Weekly total vs last week. The trend matters more than the absolute value.
- Share by subject. If one subject is 60% of your week and it is not your weakest, rebalance.
- Streak. Days in a row with any study time. A short session that keeps the streak alive beats a rest day that breaks it.
Skip the rankings. Another person's 13-hour day tells you nothing about your plan, and reviews of ranking-based apps are full of burnout and fake totals.
