Duolingo: Is It Really Free? Truth About Language Learning Apps

When you think of learning a new language, Duolingo, a mobile app that uses gamified lessons to teach languages. Also known as language learning app, it’s one of the most downloaded tools for picking up English, Spanish, French, or any of its 40+ courses. But here’s the question no one asks: Duolingo is free to use — but is it free to learn?

Duolingo’s free version lets you practice daily, earn streaks, and unlock basic lessons. But if you want to remove ads, download lessons for offline use, or get unlimited hearts (so you don’t get locked out after three mistakes), you need Duolingo Plus, a paid subscription that removes distractions and adds offline access. Many users think they’re learning fluency, but the app only builds vocabulary and grammar patterns — not conversation skills. Real speaking practice? That’s still on you. And if you’re serious about English or another language, you’ll quickly realize Duolingo is a warm-up, not the full workout.

It’s not the only tool out there. Apps like English speaking app, software designed specifically to improve spoken fluency through real conversations and feedback. are built for people who want to talk, not just tap. Duolingo works best as a daily habit builder — a 5-minute boost between classes, commutes, or breaks. But if you’re aiming for real fluency, you need more: listening to native speakers, writing essays, correcting mistakes with a tutor. That’s where the real cost isn’t money — it’s time.

So what’s in the collection below? You’ll find honest reviews of Duolingo’s features, comparisons with other apps, and real data on whether it actually helps you speak better. We’ll show you when to stick with free, when to pay for Plus, and what else you should be doing alongside it. No fluff. Just what works — and what doesn’t — when you’re trying to learn a language on your own.
