The best app is whatever you use to consume media in the target language.
The only way to acquire a language is to expose yourself to it in a natural context. You can’t acquire a language just by studying with flashcards or grammar exercises or whatever – any app that offers enhanced versions of those will at best be a minor supplement to actually using the language.
I quite like busuu for Spanish so far. It is a lot better than Duolingo trash as it actually explains things rather than just throwing stuff at you that is often incorrect anyway.
I started using Busuu yesterday: I like it too for the languages they have, and while they don’t have all languages they make up for it with good learning materials.
Though I’m not sure about the inclusive words for French due to my convictions as a Christian.
What do you mean by “I’m not sure about the inclusive words for French due to my convictions as a Christian”?
Oh, there’s a new course on Busuu for French that I don’t like that deals with inclusive terms I’m probably not confortable talking about anymore since they deal with genders and sexuality.
I’m trying to be a Christian instead and not talk about those things in my faith, but that doesn’t mean I’ll be learning what is supposed to be teaching me French with weird terminology.
