I am sure most of you have heard of Anki flashcards? Using spaced-repetition is one of the best ways to learn more vocabulary when learning a language.
However, I find flashcards super boring. I've been playing some crossword games in my target language, Spanish, but I wished that I could use my custom list of words that I've come across instead of random words.
That gave me the idea to create this mini-app. It's super simple. Add your words and you get unlimited crosswords with spaced-repetition! If you get a word right you won't see it for the next few days.
Works with most languages (I doubt it works with Arabic or Chinese for example).
You can add words one by one or import a CSV (just make sure to follow the columns: word, answer)
It's a PWA, so you should be able to install it via your browser and it should work offline!
There's still some bugs and QoL things to add but let me know what you think!
