I’ve been using Drops for about a week. I’ve “mastered” several categories by doing 5-10 minutes a day, but I suspect I’m not alone when I say I’ve mostly forgotten the words in the first couple of categories I learned.
Does Drops offer some way of reviewing words that I have supposedly “mastered”? Other apps I’ve used offer a spaced repetition system to test words less and less frequently when I continue to get them right; Drops could really use such a study aid.
As it stands now, my experience of Drops is a fun tool for learning a handful of words at a time, and then forgetting them. I hope this is improved in future!
