Learning statistics
Understand per-page review history and workspace Statistics for trends across your learning pages.
Learning & Scheduling · Updated 2026-05-30
Yuhimo keeps review history so you can see patterns in your self-assessment over time.
Statistics summarize grades you already chose — Again, Hard, Good, or Easy. They do not judge whether your answers were objectively correct.
There are two views: workspace-wide Statistics and per-page Learning statistics on an individual learning page.
Two places to look
- Statistics — workspace overview for the last 7, 30, or 90 days
- Learning statistics — history and charts for one learning page
Open Statistics from the main learning navigation when you want trends across pages. Open Learning statistics from a learning page’s toolbar when you want detail for that page only.
Workspace Statistics
The Statistics page is a read-only dashboard. It uses reviews you completed in the selected period and your account timezone for calendar-day grouping.
You can switch the reporting window between 7, 30, and 90 days.
- Total reviews — how many review grades you logged in the period (each page counts at most once per calendar day, same as sessions)
- Average grade — mean self-grade on a 1–4 scale (Again through Easy); the label is a bucket from that average
- Reviews over time — bar chart of review counts by day
- Hardest topic — page that ranked weakest by average grade or difficulty in the period
- Most stable topic — page with the longest stability (longest interval before due again)
- Top hardest / most stable lists — ranked pages in the period
- Topics getting harder — pages where recent grades or rising difficulty suggest more struggle
Lists may be empty until you have enough graded reviews in the window. Tap a row to open that page.
Per-page Learning statistics
On a learning page, Learning statistics opens a panel with that page’s review log only.
- Total reviews and Again rate for this page
- Current stability and difficulty (from scheduling state after your latest reviews)
- Stability over time — chart of the last 90 days of graded reviews
- Review history — date, grade, interval, stability, and difficulty per review
Stability in the chart is shown in days — an internal estimate of how long recall is expected to hold at the current difficulty, not a guarantee you will remember on a given day.
What statistics do not do
- Score correctness of your answers to questions
- Replace honest self-assessment when you review
- Change due dates or scheduling by themselves
- Prove mastery of a topic
- Include pages that are not learning pages
Grades still drive scheduling through FSRS-light. Statistics are a mirror of that history.
How statistics relate to scheduling
Each saved review updates stability, difficulty, and the next due date. The history table and charts show those values after each grade.
You usually interact with due dates and grades, not raw numbers. For what stability and difficulty mean, see Stability and difficulty.
When to use which view
- Use Statistics when you want weekly or monthly habits, workload, or which topics feel hardest lately
- Use Learning statistics when one page keeps getting Again or when you want to see how intervals grew for that note
FAQ
- Why is average grade different from my last grade on a page?
- Average grade on Statistics is the mean across all reviews in the period. Your last grade on a page is only the most recent row in that page’s history.
- Why is the chart empty for a page I review often?
- The stability chart needs graded reviews with stability data in the last 90 days. Very old logs fall outside the range.
- Do statistics work offline?
- No. Statistics read live review history from the server. Offline mode is read-only for cached pages and does not record new grades.
