A year of study at a glance
The Review Activity card on My Progress has been rebuilt as a 365-day heatmap — one cell per day, coloured by how many reviews you completed. The old 30-day area chart is gone.
Why the change
- A whole year in one glance. Streaks, quiet weeks, and comeback bursts show up in the same view.
- Zero clicks to compare. No need to change a date range — the heatmap always covers the last 365 days.
- Familiar shape. Same visual language as the activity grids you already know from GitHub-style contribution charts.
Existing 30-day empty-state behaviour is unchanged: if you have no SRS activity yet, the card still hides itself rather than showing an empty year.
