Review Heatmap for Anki

Your learning performance at a glance

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 on that day.

The easiest way to install Review Heatmap is through AnkiWeb.

Manual installation

Please click on the entry corresponding to your Anki version:

Anki 2.1
  1. Make sure you have the latest version of Anki 2.1 installed. Earlier releases (e.g. found in various Linux distros) do not support .ankiaddon packages.
  2. Download the latest .ankiaddon package from the releases tab (you might need to click on Assets below the description to reveal the download links)
  3. From Anki's main window, head to ToolsAdd-ons
  4. Drag-and-drop the .ankiaddon package onto the add-ons list
  5. Restart Anki

Video summary:

Anki 2.0
  1. Go to ToolsAdd-onsOpen add-ons folder
  2. Find and delete the Review file if it already exists.
  3. See if you can find a review_heatmap folder. If so:
    1. If the folder contains a meta.json file, copy the file to a safe location. This will allow you to preserve your current settings.
    2. Proceed to delete the review_heatmap folder
  4. Download and extract the latest Anki 2.0 add-on release from the releases tab (you might need to click on Assets below the description to reveal the download links)
  5. Move the extracted Review and review_heatmap into the add-ons folder
  6. Optional: Place the meta.json file back into the directory if you created a copy beforehand.
  7. Restart Anki


The use of the add-on is documented in the Wiki section and a series of video tutorials on YouTube. More information may also be found in the AnkiWeb description.
