One Year with Duolingo - Is It Actually Effective?

July 27, 2025

The email I received was in German, but I translated it into the English version.

I received an email from Duolingo today letting me know that it's my first Duoversary, and I figured this was a good opportunity to reflect on my experience with the app - and maybe brag a little about my achievements.

Let's get the bragging out of the way first: I've maintained my daily streak so far, even if I don't always complete all the daily quests. I've reached the highest league (Diamond League), remained there for 26 consecutive weeks so far, and even secured first place in the Diamond Tournament back in June. While I'm not particularly driven by competition, achievements do tend to spark a bit of that competitive edge in me.

My achievements from early June.

I've unlocked almost all the achievements - except for the friend-related ones. I've chosen the lone wolf route, which, in my opinion, makes the accomplishments all the more rewarding. I'll probably go for the friend-related ones eventually, just to have them, though I haven't really cared so far. That said, Duolingo has occasionally forced friend streaks and friend quests on me with randomly selected users, without giving me the option to opt out. I don't mind the concept in general, but I do question why it has to be mandatory. Anyway, that's enough about the gamification side of things.

So, the big question: Do you actually learn something with this app? In my experience - yes, you do. It depends heavily on the subject, though. When it comes to languages, it's definitely effective. For example, I was already fluent in English before I started using Duolingo, but I've still picked up new vocabulary, useful phrases, and subtle grammar improvements. I'd say it's a solid tool for language learning - great for daily practice and vocabulary, though not enough to develop strong speaking and listening skills on its own.

Beyond languages, I also tried the music lessons. They're useful for building a basic understanding of how to read sheet music, but not much more. Don't expect to walk away able to play an instrument (aside from maybe a few simple melodies on a keyboard).

All in all, if you're consistent and know what to expect, Duolingo can really help build foundational skills - especially in languages.
