Most study trackers give you one number: total hours. It feels good. It also tells you almost nothing you can act on.

The problem with a single number

Say you studied six hours today. Great — but six hours of what? If five of them went to the subject you already enjoy and one went to the one you're failing, the total looks identical to a perfectly balanced day. The number hides the exact thing you need to see.

Averages comfort you. Breakdowns confront you. Only one of them helps.

What subject-level tracking reveals

When every minute is tagged to a subject automatically, patterns show up that you'd never notice otherwise:

None of that is visible in a total. All of it is obvious the moment the hours are split by subject.

Make it automatic or it won't happen

The catch: manual logging dies within a week. Nobody tags sessions by hand for a whole semester.

So the tracking has to be invisible. In Stratum you pick a subject when a session starts, and every second after that attributes itself. The breakdown builds while you work — no spreadsheet, no logging, no willpower tax.

Study the data, not the guilt

Once you can see the split, the fix stops being "study more" and becomes something specific: give that subject two more sessions this week. That's a plan. "Study harder" never was.

Hours tell you that you worked. Subjects tell you whether you worked on the right thing.
