Anki is free. If you need gamification, then perhaps memrize is for you. I’d just go with anki though. Ankidroid is a good app to work with the anki decks.

I tried out a bunch, including Babbel, Busuu, Language Transfer, Mango, and Memrise. I didn’t like them for one reason or another. I finally landed on Lingodeer. It’s similar to Duolingo, but it is a paid app. (You can try level 1 of any language for free.)

The regular subscription price is definitely not worth it. It’s okay (not great, but not awful) when they do their sales. But I felt okay about paying human workers.

This kind of learning is a great start, but will only get you so far. If your local library has access to Kanopy, look for the Great Courses series on Spanish. I thought that was an excellent series after a little bit of Duolingo.

Use free Anki and get a free 1k or 5k high-frequency community deck from Anki website. Or get Refold 1k deck (paid) for anki.

If you don’t mind paying sub (look for discount/vouchers), use lingvist (paid) or memrise (not sure how this app is now after the changes) to learn 1k words. Cancel subscription once you learnt 1k or 2k words, probably will take 1-3 months. Learn about 15-30 words a day.

Try reading graded readers with audio at the same time.

Read up on some basic high frequency grammar in your target language.

Depending on language you will have to also actively learn the alphabet, numbers, phonic and so on.

The idea is to learn high frequency vocab and get to consuming content (using language) as soon as possible not collect gems, coins or whatever.

If you like keeping scores, count the books/article read, count the words learnt, count the hours spend listening don’t count coins or gems.
