Worth knowing

Duolingo has over 500 million registered users — more than the population of most countries it teaches languages from.
Babbel's courses are designed around real-life dialogues, so lesson one might teach you to order coffee, not name zoo animals.
A 2020 City University of New York study found ~34 hrs of Babbel equivalent to a full college semester of Spanish.
Duolingo offers courses in High Valyrian and Klingon — fictional languages Babbel would never touch.
Babbel has live online classes with human tutors available as an add-on, something Duolingo doesn't offer.

Duolingo's mascot Duo the owl was deliberately made passive-aggressive as a joke — then users genuinely started feeling guilty about disappointing him. The meme became the marketing strategy.
