I just tried it out and I like it a lot better than duolingo.

Duolingo is super gamified and you can’t keep practicing after you made a few mistakes. I just practiced for an hour with memrise and it was nice. There’s also video exercises in the app, and you can also practice chatting (with an AI probably?). I hope it holds up.

I would love to compare babbel too, but Arabic is not available there.
