Sync Learned to TickTick [Support Thread]

Support thread for all questions related to the “Sync Learned to TickTick” Addon.

“Sync Learned to TickTick” syncs your daily “studied today” stat to a habit on the TickTick platform.
This can be useful for visualising your daily learning process but also to simply keep yourself motivated.

Feel free to ask any questions regarding this Addon right here!
Please check the documentation below if your are unsure that you have everything set up correctly.

Fill these in before use! The Addon won’t work with these left blank.

  • username: Your TickTick Mail

  • password: Your TickTick Password.

Info: TickTick sends your password via. HTTPS which is secure, but you should still be careful because adding it here adds it to a file on your computer! If you are uncertain about adding your password here you can check the complete source code of this Addon by clicking “View Files” on the right side of the Addon-Window.

This addon syncs only by the habit name, so feel free to change the habit in TickTick as you please. The only thing that this addon changes is the card count of the current date.
Automatically syncs when the “sync” button is pressed or activated in any other way.

These fields configure the plugin for your personal use. Keep in mind that you can also sync the plugin to a already existing habit by entering its name as the habit_name here.

  • habit_name: The name of the habit in TickTick. Warning, this has to match the case-sensitive name of the habit. If you change the name in TickTick, change it here as well!

  • target: Daily target for cards. Only affects the habit if it is newly created

  • unit_name: Name of the units. Only affects the habit if it is newly created

Known Restriction
This Addon will not work if you are at your habit-limit! (5 for free accounts). There is nothing I can do about that.



Version 1.1 (March 25th 2023):

Major Changes/Additions:

  • Added a synchronization to the new “Timer” feature in TickTick
    • Automatically creates a new Timer linked to the habit
    • Syncs all learned times >5 minutes to this Timer

Minor Changes/Fixes

  • Signs in on application start-up, reducing the “freeze” time of each sync caused by this addon.

  • Signs out when closing, reducing the token-spam

  • Fixed multiple small bugs/issues

  • Upped the supported versions to 2.1.60+

I tested these changes as best as I could, but especially the addition of the sync to the timer is a big new feature that might introduce errors. Please contact me if you encounter any new unwanted behaviour

Hi, first of all just wanted to say I love your addon. Used it March-May no problem.

Unfortunately, lately it is not working, and giving this error on startup:

No longer works on 2.1.65

An add-on you installed failed to load. If problems persist, please go to the Tools>Add-ons menu, and disable or delete the add-on.

Hi there.

Really sorry for answering this late! Unfortunately it turns out that my notifications for this forum aren’t properly set-up…

The issue you described has been fixed about a month ago, so simply updating should resolve everything. I also just now added a small fix that might have affected your use.

As always if you have any suggestions, feel free to share!


Hi! Thanks for making this add-on and keeping it updated thus far. I LOVE Ticktick, and I love Anki, so this was a wonderful integration of both!

I first installed the Add-on in Jan 2024. It had been working for great for me until 3/5/2024 when it stopped syncing to my Ticktick. I can’t figure out why not, and Anki said there’s been no other recent updates to the Add-on. Please see the Debug Info below. Thanks in advance!

Anki 23.12.1 (1a1d4d54)  (ao)
Python 3.9.15 Qt 6.5.3 PyQt 6.5.3
Platform: macOS-14.2.1-arm64-arm-64bit

Hi, thank you for the bug report!
I just implemented a fix that works on my end, please update your plugin and test if it also works for you.

The issue was caused because the login-request was send pretending to be a rather old firefox version which is no longer supported by TickTick which I just increased to a newer version, so hopefully we won’t be having that issue for a long time now.
