Pretty good, as long as it’s free or cheap
They keep bugging me for a review, so here it is, after about ten years of use. I don’t remember if I paid anything for this; maybe it was a dollar or something. So I can’t really complain, but there are some really nonsensical aspects to this app, like not clearly stating the gender of nouns: you have to dig around and find the gender by inference, for instance how it appears in a sample sentence. Sometimes you can’t find the gender at all. Also, when you’re looking up a word in Spanish, the definition includes sample sentences and usages in English, which belong in the English definitions, not the Spanish ones.
