I've been practicing Russian on Duolingo almost every day since February 2020, and before that I had a few 30 to 100 days streaks over a few years (can't remember 100% for sure). Making you force yourself into learning a new language is what makes Duolingo stand out among all the other tools I've tried.

I think that the tool that is the most efficient in teaching you a new language is the tool that makes you force yourself into learning, at least a little, every day. I'm quite sure that consciously practicing 10 minutes every Monday-Saturday for a year [1] is more efficient compared to practicing two hours every day for one week every three months [2], even though it adds up to approximately the same amount of time spent yearly on learning the target language.

[1]: (10 minutes * (365 days - 52 Sundays)) / 60 minutes per hour ≈ 52 hours and 10 minutes [2]: 2 hours * 7 days * 4 quarters = 56 hours per year
