For Duolingo, you might mix it with other materials for a much better experience. I told our kids' experience learning foreign languages here [1]. My wife used the same technique to learn some French, Duolingo reinforced with audio and visual materials, songs with lyrics, regular learning books, podcasts etc.

Duolingo is used daily in our house and we're paying for not seeing ads.

This proves the OP's point. Duolingo is trash if you aspire to fluency. It's only useful in fluency as an additive to a robust training program. You don't get fluent by following Duolingo alone.

I disagree. Duolingo is not trash as the op suggests, it's a great fire starter and makes you able to use other materials by handling the intro well. Peppa Pig is a sustainable language learning tool if you did something before to learn the basics and Duolingo handles that part well for free. How is that trash?
