I Had a 500 Day Streak on Duolingo

In 2025, I completed a 500 day streak on Duolingo and was in the top 3% of global users. According to the app, I was learning faster than 95% of other learners. By then, I had reached an A2 level of German (score 43), which meant that I should be able to hold basic conversations.

Those are pretty impressive stats.

And yet I have had several public embarrassments when speaking German.

The word richtig (which means “correct”) tends to bring conversations to a screeching halt. I’ll say it confidently, and the person I’m speaking to will pause.

“Are you trying to say Frühstück (breakfast)?” They’ll ask.

No, I am not.

I am saying richtig… or at least I think I am.

There is a gap between my online stats and my real world abilities. And I will use this post to explore why that is.

My Fluctuating Experience With Duolingo

I ran into a problem when writing this post, though, which is that my experience with Duolingo fluctuated significantly throughout my 500+ days.

None of these pros or cons are set in stone, and that is partially a problem in itself.

It is a characteristic of many online learning platforms.

The rapid pace of change can greatly impact user experience, for better or for worse. And this makes it hard to sign up for an annual subscription when so much about the app can change within a year.

All it takes is one update for you to go from loving it, to hating it, or vice versa.

Even though the learning is “self-directed”, it is at the mercy of forces that the user has no direct control over.

As such, this article is part testimonial, part consumer protection essay, and part cultural critique based on my own experience.

So let’s discuss some of the things Duolingo did well…

What Duolingo Did Well

1. Adaptability

Flexibility

The app offers flexibility and convenience. A person can learn a new language anytime, anywhere, at their own pace, with no need to schedule or attend lessons. You only need to pull your phone out of your pocket.

And a lesson only takes a few minutes, easy to fit into your day.

This flexibility works for both the crammer and the slow and steady learner. Neither has to contort their life into the rigid structure of a traditional classroom.

Scalability

Duolingo also scales to your ability.

At one point, I handed my phone to a friend who completed her PhD in a German-speaking country. She ended up having a 10 minute conversation with the AI, talking about complex topics like global affairs and recycling.

I had no idea the AI could be that thorough as my conversations with the AI usually come to an end after about 1 minute of basic conversation.

It showed me that there is significant depth to the app that I wasn’t yet able to explore based on my own skill level.

2. A Low Pressure Learning Environment

Digital classrooms have lower social stakes.

In a way, I really enjoyed the early social isolation of it. I could make my beginner mistakes in private. I didn’t have to sweat about a low grade or any public humiliation. I could just redo the exercise.

It made learning feel more relaxed and fun.

I remember the same friend who did her PhD in German crying after an early German lesson with a human teacher. She ended up quitting because the teacher was too harsh and expected too much from a beginner.

Duolingo never made me feel that way.

3. Societally Recognized Metrics

Despite the solitude that comes from learning a new language this way, Duolingo as a company, has done an excellent job at being highly socially recognizable.

When you think of learning a new language, you think of Duolingo.

The app allows you to go on “Friend Quests”, compete with other users, and now even include your Duolingo score on your LinkedIn page.

These metrics and societal recognition are meaningful.

Comparatively, I did a 52-Book Reading Challenge in 2025.

When I told people about it, they didn’t really know what to think of it. Why do that? was their response. To them, it didn’t seem as legitimate as say, going back to school, even though I learned just as much, maybe more, than if I had.

But when I told people I was in the top 3% of Duolingo users, they were impressed… even though I put less effort into Duolingo and learned much less than I did from reading those books.

The societal recognition that came with using Duolingo made me feel more productive and boosted my spirit, even though I was learning more in other ways.

4. Cheaper Than In-Person Learning

I purchased Duolingo Max: the highest subscription tier of Duolingo, for $168 USD/ year.

At the time, it felt justified.

An in-person class or tutor would cost significantly more.

Duolingo saw a genuine market gap and sought to fill it: giving users access to high quality language learning at a cheaper price. And I jumped at it.

In my mind, that gap still exists. But Duolingo has strayed from it.

Where Duolingo Falls Short

1. The Value of the App is Decreasing

About halfway through my 500+ days on the app, Duolingo founder Luis von Ahn introduced the bold “AI First” strategy.

It was meant to decrease costs, and therefore theoretically improve the quality and quantity of content offered.

But this hasn’t been the case in my experience.

I noticed words began to be mispronounced by the AI, such as the word “Gut” (“good” in German). It is supposed to sound like “goot”, but the AI would say “gut”, like a human abdomen- and that is a pretty basic word.

My conversations with the AI felt less like a human-to-human conversation, and more like one with an AI customer service agent. You can imagine how frustrating and circular those can be.

In fact, the quality decreased so significantly in recent months to the point where I let my final few months of my subscription pass without using the app at all.

As AI starts to become more integrated into the platform, the value proposition starts to shift even more.

I began asking myself:

Why am I paying for this?

Especially when there are free AI tools that can do similar things.

When I first started, I justified the high price tag because Duolingo gave me something I could not otherwise afford: easily accessible, high quality lessons designed by humans.

The value was in the balance: human-designed content, digital convenience. As that balance is starting to tip, the cost gets harder to justify.

2. Enshittification Has Reached the App

AI isn’t the only cause of the app’s declining quality, though. Enshittification (the tendency for online products and services to worsen over time) had already started to take hold.

I wasn’t using the app during its heyday, but I hear blissful rumours of online forums, learning groups, chat features, a better quality of app for free users, and a “tree” learning structure where users could choose their own lessons- not a rigid one like today.

It seems more social and less commercialized back then.

Although, apparently some of these changes came for good reason.

Duolingo now limits users’ ability to chat with other users apparently because of alleged abuse that was occurring when the app had an open forum. This issue was especially problematic because Duolingo has a large user base under 18 years old.

Moderating these chats and forums was simply too costly, so they were shut down.

Still, language is inherently social.

And Duolingo intentionally limits this social interaction.

At one point, I had a Duolingo friend called “Mieke” who was learning Spanish. That’s all I know about this person; yet, I had a months-long friend streak with them. Then suddenly one day, they were gone.

I tried in vain to gift them “streak freezes” so they could come back, but they never did.

This was around the time of the “AI First” update, so I think I understood why. Still, I was sad.

This had been a person who I had interacted with digitally for months; which was more interaction than I had with some of my actual real-life friends during that time. You get used to seeing someone’s name pop up on your phone.

Duolingo offered no way to communicate further with this person or learn more about them. And that felt like a missed opportunity.

I don’t think Duolingo should have kept dangerous chatrooms.

But that could have been a personally and culturally enriching relationship; and it was intentionally limited to fit into the app’s structure.

It also provides an example of the myth of cheap scalability. There are often a lot of costly practicalities that come along with “efficient digitalization”.

And is this how learning a language is supposed to feel? This isolating?

3. Can Gamification Ever Truly Be Educational?

The Social Problem

Duolingo experienced a problem that many online learning tools have experienced: a move away from nuance and soft skills toward concrete, measurable ones.

But language learning is full of these soft skills. It requires understanding pronunciation, cultural nuance, references, and body language. And it is hard for Duolingo to replicate these.

Instead, it shifts the focus from human interaction to digital gamification.

The Digital Problem

Duolingo is, at its core, a game.

And that is both its strength and its weakness.

The streaks, notifications, sounds, bright colours, and digital incentives are all designed to keep you engaged. And it works… kind of.

But, for me, the owl began to verge on uncomfortable at times.

And in the days of algorithmic escalation and “AI psychosis”, I am starting to question the ethics of holding someone’s attention in this demanding way.

It made me realize that I have never in my life had a human teacher send me a watery-eyed emoji telling me they’re “not that upset! It’s (just) allergies…” because I didn’t do a lesson.

The emotions that these push notifications elicit are genuine. And the “low pressure learning environment” that I had talked about before was morphing into a high pressure one.

Even my PhD friend- someone who has had to defend her thesis at the highest possible level in German- ended her 25-day streak because “the owl was too stressful”.

It seems absurd, and a little funny that the owl pestered her to learn more on a daily basis than her industry-leading supervisor did.

But has the Duolingo owl earned the right to this bossiness?

On the other hand, some people like having a virtual owl to motivate them. To each their own. And many of these people even grew upset when the owl became inexplicably stuck on sad mode, or when the owl “died” as a marketing stunt.

In these cases, they lost the motivator that they came to rely on because it no longer responded to their effort.

Sometimes these situations land and sometimes they don’t.

But each of these cases demonstrate how symbiotic the relationship is between teacher and student. It is important that the (human or digital) teacher respond to their student’s energy. And it shines a light on perhaps another myth of digital learning: that it adapts quickly.

The idea of a rapidly evolving digital teacher seems clunky compared to how quickly a good human teacher could react to their student’s energy.

Adjusting the digital teacher takes so much work behind the scenes: board meetings, test groups, developer discussions, rollout, etc., and it is responding to all users all at once.

A human teacher’s scope of responsibility is much less than this.

And as such, human teachers have a much greater ability to adjust to their student’s needs in the moment. Good teachers can read the room in an instant, and make adjustments. Duolingo, and (to be fair) my friend’s bad German teacher, could not. And it caused learning to stall, motivation to wane, and alternative solutions to be sought.

Is Constant Stimulation the Best Way to Learn?

Another difference between online teachers and in-person ones seems to be a matter of engagement strategy. App developers seem to strive for maximum stimulation to keep users engaged and learning.

They want to keep your eyes glued to the screen.

But is that really the best way to learn?

I don’t always like being bombarded with notifications and bright colours. Especially when I have a migraine. In those cases, I’d rather put on a German podcast and relax in bed.

constant stimulation ≠ good user experience

The bright colours and sounds are good for making the app engaging, but sometimes I need a more chill version of Duolingo.

And when it would aggressively try to hold my attention when I was sick, had a death in the family, or was simply busy with more important things, I grew resentful and checked out.

4. Independence Can Work Against You

Duolingo created the aggressive owl to combat a problem that is particularly prevalent with online learning: user independence can work against them.

In these formats, there is no teacher to hold you accountable, no one to reprimand you if you slack off, or just do the easy lessons.

There is just the owl.

The freedom that Duolingo offers is powerful- but it requires discipline, which can be easy to have at first, but harder as time goes on and you realize how hard it is to learn a new language.

Digital feedback can be motivating in the short-term, but I think long-term human connection and support would go a long way to turning it into a long-term habit.

So… Can I Speak German?

According to Duolingo, yes.

In real life?

Not really.

My reading comprehension is certainly better than my ability to hold a conversation, even with all of those AI phone calls that I practiced.

Duolingo trained me to be a consumer, rather than a creator of German. And in a way, that is okay. Sure, I can’t talk to you, but if you show me a page in a German book I can tell you the rough outline of what is going on.

And that is certainly an improvement from where I started.

But there are real limitations to learning in this way; something genuine is lost.

Language is partially about understanding others, and partially about being understood.

And I am struggling with that last part.

Going Forward

Duolingo will continue to evolve, fixing what isn’t working and leaning into what is.

But I will not renew my Duolingo subscription.

I want to learn German, not pay to be a guinea pig.

Instead, I will look for new ways to learn German that are human-based, affordable, fun, and hopefully more social.

I am still motivated to learn. But I’m no longer interested in systems that reward progress without substantially producing it.

Have you tried Duolingo? I’d love to hear about your experience.
