This app is more like “LAMP” (Language Acquisition Made Practical) than any we’ve tried. It emphasizes LOTS of listening, lets us explore to our heart’s content, but forces us to listen repetitively to whole sentences. For $10/month, it’s the best (as far as we know). Please try it and let us know what you think by clicking “Comment,” please. https://fluent-forever.com/app/
It’s the best flashcard app out there. Read the book too, and you’ll be WAY ahead in your language learning.
