It's really exciting to open source a project, Lurnby looks cool! What do you use the spaced repetition for?
Today's been a bit of a nervous day for me actually haha, I didn't really expect this attention. Open sourcing just felt like the right thing to do for this app and because I just don't have all the skills :D
The spaced repetition at the moment is for the highlights. All highlights get marked at an initial level 0 and then move up or down depending on you reviewing them.
Eventually gets to the point where a highlight is shown to you yearly.
In the future I was thinking of doing some spacing around finished books or articles. Things like - you finished reading X 10 days ago, what do you remember?
But don't think I've thought through the details around that enough.
