Not advertising it, but I've found it's the best for my needs despite the effort it takes to stick to it.
I would liken it to an average computer user making the effort to learn and stick to Emacs because they really believe it will pay off in the long term. And SuperMemo sure has paid off for me.
Yo, I’ve been using SuperMemo for 15 years (I set up a Google Alert for “spaced repetition” years ago). I started with foreign language words but gradually it took over my entire “memory life,” including positive memories, jokes and other stuff I didn’t think I would use it for. It feels like a secret weapon that isn’t so secret, it works great but requires discipline to maintain the habit.
