Dropping a product recommendation -- my favorite spaced repetition + notetaking + learning app: https://www.remnote.com/
I'm not affiliated, just a big booster. For those familiar with Anki it follows the same conventions. It has an excellent system for managing cards. Adding cards is as easy as writing a bullet point: [front of card] == [back of card]. They got the ergonomics right and clearly know the space very well; it has the right keyboard accessibility and shortcuts and navigation. It supports the basics you'd expect like cloze deletions (fill-in-the-blank), image occlusion (cover up parts of an image). It manages assets like PDFs and images. It uses FSRS (the best SRS scheduling algorithm atm).
It has the best (optional) AI integration into a product I've seen except for the usual code-generation suspects. I'm learning spanish and can type into a bullet point something like "el vaquero ==< [tab]" and have the translation automatically generated for me into a forward and reverse card. I'm learning math and can cloze-delete parts of latex equations; the AI can very frequently generate excellent and accurate latex equations, which I can make small edits to as I'd like. These kinds of bonuses make taking live flashcard-based notes during my spanish tutoring sessions and math-based parts of classes feasible.
It's less low-level configurable than Anki and more "works out of the box" with a smaller extension system. I've had enough of trying to fiddle with Anki. Overall just excellent -- I'm not affiliated in any way. Development is very fast. Release note videos are incredible, minor updates occur ~weekly. I've run into a few bugs, especially when I was traveling overseas where internet isn't strong, but overall very pleased with it.
I've tried spaced repetition systems several times. The problem that I always discover is that I don't really have stuff that's worth memorizing. Things that are actually important I remember without trying and for the rest of the things, doing daily card reviews starts to feel like a pointless chore after a while.
His article https://andymatuschak.org/books/ inspired me to build https://readboost.io/ to embed Q&A and SRS into ePubs. Might be buggy still, but I personally found it quite useful!
I very highly recommend a blog post by this same author: [How to write good prompts](https://andymatuschak.org/prompts/). This post made spaced repetition click for me.
One of the barriers to adoption (to my adoption, anyway) not mentioned in the site author's list:
I am one of the least qualified people in the world to write cards for a topic I am learning. I would quite likely create cards that would help me memorize inaccurate information effectively and efficiently. I'd rather not take that risk.
I use a variation of an SRS for storing notes about what I've read (as well as using a regular SRS for regular SRS stuff). I chunk notes I've made from books I've read (things like Psycho-Cybernetics, 7 Habits, Iron John, etc), and review 3-4 a day, and having read them I'll clip anything that's particularly salient into "daily review" and then push back the notes for however many days, weeks, months, I think. This has worked well for me over the last 15 years or so I've been doing it.

I use it as an accompanying tool in a real language school (learning German). I started a new Study Set from scratch, and add new words to memorize every lesson. Liking it so far!
Is there a good space repetition app on Android that you recommend?
That only does space repetition?
Has anybody found a good site with pre-made cards or (ideally) some sort of play-along tracks for memorizing piano chord voicings?
it's good for cramming up stuff, say to pass exams. but for long term deep think this did not work well for me.
This is a few days worth of materials to read. If anyone finds it overwhelming, I recommend you read this comic that teaches you the basics of idea behind spaced repetition https://ncase.me/remember/
