Adds a GitHub-style heatmap to the main window visualizing past and future review activity, showing streaks and letting users click a day to browse corresponding cards.
Visualizes study activity, streaks, upcoming reviews, and new-card learning on a heatmap, with configurable workload, time, and FSRS-based scoring plus selectable date-range statistics.
Enforces a daily card minimum by blocking Anki from closing until met, while tracking streaks via a customizable heatmap and generating shareable 1080×1080 stats images.
Displays a customizable GitHub-style heatmap on the Anki home screen, tracking reviews or newly added cards with tooltips, streak statistics, and clickable browser links.
Displays review activity heatmaps, daily review goals, progressive streak levels, retention percentages, 60-day trends, and interactive card history, with customizable colors and date ranges.
Replaces Anki's deck and review screens with a customizable widget dashboard featuring activity heatmaps, Pomodoro timer, habit tracking, exam countdowns, Quizlet-style study modes, card previews, six themes, and four languages.
This is a fork of the original Review Heatmap to fix a minor visual bug affecting users in some locales, including Australia. See the original AnkiWeb add-on for more information about Review Heatmap, including acknowledgements.
Adds a heatmap graph to Anki's main window which visualizes past and future card review activity, similar to the contribution view on GitHub. Information on the current streak is displayed alongside the heatmap. Clicking on an item shows the cards reviewed or due on that day.
The original Review Heatmap was developed by Glutanimate, but has a longstanding bug affecting the display of certain days during DST transitions in some timezones. This is a simple patch built on top of Review Heatmap v1.0.1 which fixes this issue. There are no changes in functionality compared to the original Review Heatmap. This is not an attempt to create a fork; I just want to distribute a version that colleagues and friends can use until Glutanimate incorporates the fix into the main plugin.
My changes are public and I have incorporated updated build steps, if you want to compile and build the addon yourself.
