True Retention by Card Maturity

<10kB. Updated 2017-08-30.
The author has shared 62 other item(s).


This is a slightly modified version of the True Retention add-on by Strider that breaks the retention statistics up by card maturity: In addition to this, the add-on also allows you to define a custom card maturity threshold (MATURE_IVL at the top of the source code). This is set to 21 days by default. CHANGELOG 2017-08-06 – Update license 2017-04-02 – Initial release SUPPORT Please do not report issues or bugs in the review section below, as I will not be able to reply to them nor help you. Instead, please report all issues you encounter either on GitHub, or by posting a new thread on the Anki add-on support forums while mentioning the name of the affected add-on in your thread title. CREDITS AND LICENSE Copyright 2016 Strider Copyright 2017 Glutanimate All credit for the original True Retention add-on goes to Strider. This modified version is based on a post on the Anki support forums by peter19220. I wasn't able to find any licensing information for the original add-on, but since it reuses parts of Anki's code I think it's fair to assume that it's licensed under the same license as Anki itself (GNU AGPLv3). The code for this add-on is hosted on GitHub. MORE RESOURCES A lot of my add-ons were commissioned by other Anki users. If you enjoy my work and would like to hire my services to work on an add-on or new feature, please feel free to reach out to me at: ankiglutanimate [αt] gmail . com Want to stay up-to-date with my latest add-on releases and updates?

Great add-on that I discovered because of this video: https://youtu.be/1XaJjbCSXT0

Something I didn't know and would suggest be added to this add-on's description:
NOTE: In modern versions of anki (2.1.33 and newer), you ***MUST*** open the Stats window by shift-clicking in order to view addon-based stats information. If you do not hold shift, a different stats window will appear where addon-based stats ***do not display***. This behavior is ***covered in Anki's documention***.

Awesome add-on! Though it needs to be updated for Anki 2.1.33 since the stats pages was updated
