As someone who’s tested dozens of language apps over the years, I’ve spent the last two weeks using Duolingo daily to see if it’s still the best free way to learn. This Duolingo app review is part of our ongoing mobile app reviews series.

What Is Duolingo?
Duolingo is a gamified language-learning app available on iOS and Android. On the App Store, it holds a 4.7-star rating, while on Google Play it sits at 4.6 stars—both from millions of users. Its value proposition is simple: bite-sized lessons that build your skills through repetition, streaks, and rewards.
My Experience Using Duolingo
I tested Duolingo on an iPhone 15 Pro, focusing on Spanish and dipping into a bit of French. When I first opened the app, I was dropped straight into a placement test that nailed my level within minutes. Over the next 14 days, I completed around 10–15 minute sessions each morning. Here’s the thing: Duolingo’s streak and XP system really does keep you coming back. I missed one day and the app’s gentle nudge (and the “freeze” I’d earned) saved my streak—clever and surprisingly motivating.
What really impressed me was how the lessons mixed listening, speaking, and typing. For example, I had to say “¿Dónde está el baño?” into the mic, then later type it out and match it to a quick audio clip. The immediate feedback is crisp, and the prompts get progressively trickier, especially in verb conjugations. I also liked the new path layout (replacing the old skill tree) because it feels clearer where you are and what’s next.
Key Features That Stand Out
- Gamified learning: Streaks, XP, and crowns make practice feel like a game. After a week, I found myself chasing crowns in the “Food” unit just to unlock the next checkpoint.
- Short, focused lessons: Most lessons took me 5–7 minutes. Great for squeezing in practice while waiting for coffee.
- Audio and speaking exercises: The mic checks are forgiving but still catch sloppy pronunciation. I had a couple of red flags on “perro” vs “pero.”
- Personalized path: The path adapts based on your mistakes. I repeatedly messed up past tense in Spanish, and Duolingo threw in extra drills the next day.
- Stories and practice hub: The mini-stories add context and humor. I laughed out loud at a short dialogue about a cat judge—classic Duolingo quirk.
- Streak Freeze & Super Duolingo: If you care about streaks, Freeze is a lifesaver. The premium plan adds unlimited hearts, offline, and ad-free experience.
What Could Be Better
I’ll be honest—Duolingo is fantastic for vocabulary and simple grammar, but it won’t make you fluent on its own. A few pain points stood out:
- Speaking accuracy can feel generous. I had a couple of “pass” moments where my pronunciation wasn’t great.
- Hearts (lives) can be frustrating if you make lots of small mistakes early on.
- Some translations feel unnatural. I bumped into a wonky sentence about “the penguin reads a newspaper.” Fun, but odd.
Duolingo Pricing: Is It Worth It?
Duolingo is free with ads and limited hearts. Super Duolingo removes ads, adds unlimited hearts, and enables better review tools and offline access. If you’re practicing daily and hate interruptions, it’s worth the upgrade; casual learners can stick with the free plan without missing essential content.
How Duolingo Compares to Alternatives
Compared to Babbel, Duolingo is more playful but less focused on structured grammar explanations. Versus Memrise, Duolingo’s path and stories feel richer, though Memrise can be better for real-world videos. If you want a tutor-like approach, check out Busuu. We’ve covered more in our iOS apps category.
Who Should Download Duolingo?
Ideal for:
- Beginners who want a fun, low-friction way to start a language
- Busy learners who only have 5–10 minutes a day
- Anyone motivated by streaks and gamification
Skip it if:
- You need deep grammar instruction or conversational practice with humans
- You dislike ads and don’t want to pay for premium

Final Verdict
