Review Embed

This is a market I've been interested in for a long time, and I've seen a lot of apps like this. I think for any kind of SRS-related app, the most important question is whether or not there's Anki-interop. Anki's ecosystem is vast, it's extremely powerful and serious learners often have months or *years* of review data in it. Another thing I'd suggest is putting words in context and focusing more on reading. Relying on word-only SRS as a way of learning a language is pretty much a recipe for pain! I've seen people trying it ever since the AJATT blog got popular in the mid 2000s and haven't seen it go well, yet. SRS is great for characters, phonics, etc, though. It's also fine for reviewing words you've actually learned in context (as long as you're still reading and encountering them). Coincidentally, I recorded a video on this exact topic 6 years ago: https://youtu.be/3cjnP6mogEU?t=82

The word lists themselves are good , but a white board function to allow one to try drawing the character before checking would be great (see Anki). Additionally, the ability to edit cards would be good. Finally, offering the choice of traditional vs simplified characters would be great as well.
