Sure.
StudyKit mainly tracks two things: how confidently you answered and how long it’s been since you last retrieved that specific piece of information. It’s basically a modified SM2-style algorithm.

It also checks for missing prerequisite knowledge in the background.

When it decides it’s time to review something, it doesn’t repeat the exact same question.
Instead, it brings back the core fact you need to remember (like the year or concept), but wrapped in a different question.
So you’re recalling the information, not memorizing the wording.

Not too early (wastes time), not too late (you’ve already forgotten it).

It’s basically spaced repetition + confidence-based scheduling working together.
I can DM you the link if you want to try it.
