Track Your Study Time
Three tools in one — a live study timer, a manual log for past sessions, and a full subject-wise breakdown with weighted focus scoring to measure quality, not just quantity.

What this tracker does
Three tools to measure real study effort.
Live timer
Start, pause and stop real study sessions.
Manual entry
Log past sessions you forgot to time.
Subject breakdown
Time distribution + weighted focus score.
Today's analytics
Modes, metrics & worked examples
Each tracking mode, the metrics it produces, and a one-click example you can load straight into the tool.
Live timer
Real-time session tracking
User case
A student is about to start a Physics chapter. They type the subject, hit play, pause during breaks, then stop and rate focus 8/10 when done.
How it's tracked
Who uses it
- Students doing Pomodoro or deep-work sessions
- Exam preppers tracking MCAT / LSAT / SAT study
Applications
Active study tracking, Pomodoro cycles, deep-work blocks.
Manual entry
Log past sessions after the fact
User case
A student finished a 3-hour library marathon offline and wants to log it now. They enter subject, 180 minutes, and a realistic focus rating of 6 after the fatigue of a long session.
How it's logged
Who uses it
- Students who studied without a phone or laptop
- Offline learners logging language or coding practice
Applications
Offline study recovery, end-of-day catch-up, paper-based learners.
Common study rhythms & what to expect
How each study method typically shows up in the tracker — and what focus ratings to expect from each.
| Method | Rhythm | Typical focus rating | Best for |
|---|---|---|---|
| Pomodoro | 25 min study / 5 min break | 8 – 10 (short bursts sustain high focus) | Problem sets, flashcards, active recall |
| Deep Work Block | 90 min study / 20 min break | 7 – 9 (sustained but tiring) | Writing, coding, complex reading |
| Flow Session | 50 min study / 10 min break | 7 – 9 (balanced rhythm) | General academic work, revision |
| Study Sprint | 45 min study / 10 min break | 6 – 8 (solid but drifting toward end) | Lecture notes, textbook chapters |
| Marathon | 180+ min continuous | 4 – 6 (fatigue drags focus down) | Last-minute revision — expect diminishing returns |
Clear, simple, transparent
What this tracker does, and what it doesn't — no fine print.
What this tracker does
- Runs a live study timer with start, pause and stop
- Accepts manual entries for past sessions
- Shows subject breakdown with percentage bars
- Calculates a duration-weighted focus score
- Runs entirely in your browser — no data leaves the page
What this tracker does not do
- Does not persist sessions across page refreshes — use Download to save
- Does not verify focus ratings — honesty is on you
- Does not track breaks — stop the timer when you step away
- Does not replace actual studying — the data is only as good as the work
Build higher-quality study sessions
Small habits that turn 4 hours of distracted study into 2 hours of deep, measurable work.
Phone in another room
A phone on the desk — even face down — reduces available cognitive capacity by roughly 20%. Put it in another room and your focus rating will jump by 1–2 points on every session.
Rate focus honestly
If you spent half the session scrolling, rate it 3 — not 8. The weighted focus score is only useful when you tell the truth. Over time you'll see which times of day produce real deep work.
Use Pomodoro for hard subjects
When a subject feels overwhelming, switch to 25-minute Pomodoro bursts. Short focused sessions almost always score 8–10, while the same 2 hours in one block typically scores 5–6 due to fatigue.
Save marathons for revision only
Sessions over 90 minutes almost always show focus decay. Save the 3-hour blocks for end-of-term revision — and rate them honestly. During normal weeks, 45–50 minute sessions win on quality.
Track subjects separately
When you switch from Math to History, stop the timer, log the Math session, change the subject, and start again. The subject breakdown is only accurate if each subject gets its own entry.
Review subject balance weekly
If the subject breakdown shows 80% of your time on one subject, the other subjects are starving. Rebalance next week — the tracker shows you the skew, but only you can fix it.
