Polygloss alternatives

I think it's a fun way to learn new vocabulary It helps if you already have a base knowledge of the language you choose.

I learned German by moving to Germany. Immersion is always the best way to learn a language. When I came back to practice I tried some lesson based apps. The problem was that I always have to take time out of my day to practice. That was time I couldn’t be doing anything else. When I was in germany I practiced every day all day just living life. When I heard that fluent is language learning embedded into the wer browser I already use every day I said “Bingo, that is what I want, immersion in something I am already doing.” Now I can practice and take short quizzes while inside stuff I am preset doing. I practice now 10x than when I was using the other apps. Thanks Fluent!
