So I'm wondering, how do people review their notes? When? Are they using a strategy for this? Also I'm not really looking to commit to memory my notes.
Nowadays, if I don't understand something, I head to the keyboard and start explaing it in text and it pretty much always works. I rarely revisit notes, mostly to link them together and very seldomly to revise them. If I have the time to organize the notes, that's great, if not, that's fine too.
I don't know know if this will work for you though. Learning is highly personal and imo just trying to find new ways to learn things can help a lot too.
It's a note app where every note has a repetition schedule. The schedule can be dynamic (growing-shrinking) or fixed.
For example, my diary entries repeat every 365 days so I enjoy reading what my diary entries/thoughts were a year (or 2, or 3) years ago.
If you find what you need when you need it, is never doing a nonspecific review really a problem? Notes are just a tool to support you in achieving your goals. If you don't need to recall information instantaneously, skipping review-as-memorization is just fine. If important items aren't being inadvertently neglected and falling through the cracks, skipping review-as-reflection is ok too.
