I use Babbel after having taken Spanish in school (a long time ago), and it's been pretty good. Definitely just buy the lifetime version on sale (they might send you that deal if you do their 14 day trial). I just can't keep up with it sometimes, so being able to have the platform for life and not having to worry about monthly subscriptions is totally worth it to me.
It's not nearly as game-ified as Duo, but you get a lot of extras like podcasts, articles, cultural tidbits, actual games that help you learn words, etc.
