Hi,

Khan Academy used to have a system just like this, but since they are rebuilding the website they removed it.

I do not believe that they have any plans to re-implement it.

I wish they had a streak option too but I understand why they don’t :(

There used to be a streak feature but they removed it at the beginning of 2021. I really want streaks and the clockwork badges back.

Steaks are back.

It is not exactly the same, but I am still very, very happy about it.
