Is there any apps to help learn that isn’t Duolingo or Lingodeer?

I know apps is not a very good way to learn, but it's the only thing I've got time for currently, so I figure it's better than nothing

But Duolingo just got a really shitty update that makes it much harder to learn with it (Energy system that forces you to pay if you wanna do more than 2 lessons) and Lingodeer is paid-only nowadays it seems

Is there any other similar apps that's decent and free?
