Understanding Your Analytics
The Analytics page turns your timer history and grades into a picture of your study habits over time. Navigate to Analytics (📈) in the sidebar to open it.
This page describes the student's Analytics page. Parents and supervisors see the same charts on the Analytics tab of a student's profile: see the Parent Guide or the Supervisor Guide.
Summary statistics
At the top of the page, four cards give you an at-a-glance overview of the selected time window:
| Card | What it shows |
|---|---|
| Total Study Time | Total minutes from completed timer sessions in the selected window, formatted as hours and minutes |
| Sessions | Number of completed timer sessions in the selected window |
| Weekly Average | Your average study time per week (total time ÷ number of weeks selected) |
| Peak | Your most productive day of the week and hour of day, based on where your sessions cluster |
If you have no completed timer sessions, all four cards show –.
12-Week Study Progress
The progress chart shows how many minutes you studied each week, broken down by subject.
- Each stacked bar represents one ISO calendar week (Monday to Sunday).
- Bar segments are colour-coded by subject — each subject gets a consistent colour within the page.
- A dashed line shows the 4-week moving average of your total study time, smoothing out one-off weeks so you can see the trend.
- Weeks with no sessions still appear in the chart as empty bars — this makes gaps in your routine immediately visible.
Good for: spotting whether your study time is growing, shrinking, or inconsistent over the term — and which subjects are getting most of your attention.
Effort vs Grades — Impact Indicator
This section compares how much time you've studied each subject with your average grade for that subject.
- Each dot on the chart represents one subject. Subjects further to the right have more study time; dots higher up have a better average grade.
- Grades shown are your all-time average, not just grades from the selected window. This gives a truer picture — a grade you received three months ago still reflects the work you put in, regardless of which window you're viewing.
Correlation indicator
When you have at least 2 subjects that both have study time and grades recorded, a correlation indicator card appears below the chart. It tells you whether studying more tends to lead to better grades for you:
| Indicator | What it means |
|---|---|
| Strong positive 📈🎯 | Consistently, more study time goes with higher grades |
| Moderate positive 📈 | A general trend — more study tends to help |
| Weak / no correlation ➡️ | Study time alone isn't predicting your results — other factors may be more important |
| Negative 📉⚠️ | More study time is going with lower grades — worth discussing with a teacher or tutor |
The correlation indicator requires at least 2 subjects with both recent study time and recorded grades. If you see "Not enough data yet", record grades for your subjects (or ask your parent to enter them) and use the timer more — the indicator will appear once the minimum data is available.
At-Risk Subjects
The At-Risk panel highlights the subjects where your grade average is below 75%. It shows at most 3 subjects — the ones with the lowest averages — with colour-coded labels:
| Average | Colour | Label | What to do |
|---|---|---|---|
| Below 50% | 🔴 Red | At-Risk | Prioritise this subject urgently |
| 50%–59% | 🟠 Orange | Warning | This subject needs extra attention |
| 60%–74% | 🟡 Amber | Monitor | Keep an eye on this subject |
| 75% and above | — | — | Not shown (on track) |
A few things to note:
- At-Risk uses all-time grades, not the selected window. Changing the 4-week / 8-week / 12-week selector does not change which subjects appear here — it always reflects your full grade history. This is intentional: a subject you struggled with last term is still at risk even if you haven't studied it recently.
- If all your subjects are averaging 75% or above, you'll see a green "All subjects on track" message instead.
- If you have no grades recorded yet, the panel shows a prompt to add grades.
Study Patterns
The Study Patterns section shows when you tend to study most.
By hour of day
A bar chart showing how many minutes you've studied in each hour of the day (e.g., 8 am–9 am, 9 am–10 am). Your peak study hour is highlighted. Only hours where you have actually studied appear — hours with no sessions are not shown.
By day of week
A bar chart showing your study time for each day of the week, Monday through Sunday. All 7 days always appear, even days with no sessions. Your busiest day of the week is highlighted.
By subject
A donut chart showing how your total study time is distributed across subjects. This is aggregated across all weeks in the selected window.
On mobile, these three charts are shown one at a time. Use the By Hour / By Day / By Subject tabs to switch between them.
Good for: discovering your natural study rhythm — which days and times you're most productive — and using that to schedule future sessions.
Changing the time window
Use the 4w / 8w / 12w selector (top right of the page) to adjust how many weeks of history are shown.
| Option | Covers | Good for |
|---|---|---|
| 4 weeks | Last 4 weeks | Recent performance, current sprint |
| 8 weeks | Last 8 weeks | Half-term or mid-semester view |
| 12 weeks (default) | Last 12 weeks | Full-term view |
The selector affects the Progress chart, Impact indicator, and Study Patterns. The At-Risk Subjects panel is always based on all-time grades and does not change when you switch windows.
What counts as study time?
Only completed timer sessions count toward your analytics totals:
| Session type | Counted? |
|---|---|
| Completed normally ✅ | Yes |
| Entered manually (offline study) ✅ | Yes |
| Abandoned or stopped early ❌ | No |
No data yet?
If you've just signed up or haven't completed any timer sessions, your analytics will show an empty state with a prompt to start your first session. That's normal — analytics build up over time. The more sessions you record, the more useful your patterns and trends become.
Start a session, study, and stop the timer to begin building your history.
Known limitation: completion rate and efficiency ratio
The analytics page currently shows study time from your timer sessions only. Two metrics described in PlanStudyBoost's roadmap — Completion Rate (planned vs completed study blocks) and Efficiency Ratio (how closely your actual time matches your planned time) — are not yet available on this page. They will appear in a future update when the study block data is connected to the analytics view.
Frequently asked questions
Why do empty weeks show in the progress chart?
Every week in the selected window appears — even weeks where you didn't study. This makes it easy to spot gaps in your routine at a glance. A series of empty bars is useful information: it tells you exactly when your study habit broke down.
Why are my grades shown as "all time" in the Impact view, not just the window I selected?
If you studied Maths intensively last month but received your exam result this week, a narrow window would show the study time but not the grade — or the grade but not the study time — making the comparison misleading. Using all-time grades gives a more accurate picture of whether your study habits are translating into results over the longer term.
My At-Risk subjects didn't change when I switched from 12 weeks to 4 weeks. Is that correct?
Yes — at-risk is calculated from your complete grade history, not the selected window. See At-Risk Subjects above.
My analytics shows a different day of the week than I expected. Is there a bug?
Analytics always use the timezone saved on your account. If it isn't set correctly, sessions may be grouped into different days than you expect. You can't change your timezone yourself yet: the Profile page has no timezone setting. Contact your administrator (see Timezone).
Can I export my analytics data?
Not yet — export is planned for a future release.
