I would probably stick to Anki, I'm a little suss about the app. The website is https://fluent-forever.com and the book outlines a method for using Anki to learn languages. The approach is to start with pronunciation first, then work on phonics, then vocabulary, then grammar rather than learning a bunch of canned sentences.

The book mentions moving on to movies and tv shows when you have a decent grasp of grammar and know the ~800 most common words in your target language. I have a trip to Spain coming up and my plan is to spend the last two weeks before I go watching movies and reading/listening to audiobooks in Spanish. (Listening so I can follow along while reading.)

I'm very happy with my progress so far after having little luck with Rosetta Stone and Duolingo.
