I'm also a fan of Anki, I never create cards on mobile (though review them almost exclusively there), but from desktop you can check out https://github.com/MFreidank/AnkiVim and https://metacpan.org/pod/Anki::Import. Raw cards are just text, and you can create them with any editor. https://github.com/corollari/ankiTab is also awesome for reviewing.

If you want more theory about Anki / Spaced repetition, https://www.gwern.net/Spaced-repetition is the ultimate resource on topic
