Spaced learning

Hi,
I’m student and I need something what I have on Shortcuts on my iPhone.
It’s something called spaced learning. When I put the first date of my learning, it automatically put revision 5 days after, 21 days after, 51 after and 81 days after… Just that
If I see a lesson the 21/01, I will have to relearn the lesson the 26/01 (J5) then the 11/02 (J21)…
And I want to see them in my iCloud calendar
I don’t think it’s difficult but I don’t have skills.
Thanks in advance

I don’t think it’s difficult but I don’t have skills.

That’s probably a bit more ambitious that it might sound, at first.

An iOS version of an existing tool like Anki might serve you well.

I’m not sure if this is exactly what you had in mind, but this shortcut will ask you for a description and then add the description as an all day appointment on your default calendar at defined intervals.

Hope this helps or at least can point you in the right direction.
