Learning a new language is exciting, but choosing the right app can be tricky. Two big names in the game are Mondly and Duolingo.

I’ve tried both, and while they share the same goal, their approaches are very different. Duolingo makes language learning feel like a fun game, while Mondly focuses on real-world conversations with speech recognition.

So, which one actually helps you learn faster? Which one is worth your time?

In this Mondly vs Duolingo comparison, I’ll break down Why To Choose Them One By One!

Mondly Vs Duolingo 2025 – An Overview

 Why You Should Choose Mondly?

1. Natural Language and Practical Vocabulary

Mondly excels in teaching real-life, practical sentences that can be used in everyday conversations.

Unlike Duolingo, which sometimes presents odd or unnatural phrases, Mondly ensures that its translations are accurate and contextually appropriate.

This makes it a better choice for those who want to quickly learn useful phrases for travel, business, or daily interactions.

2. Immersive Learning with AR & VR Features

Mondly stands out with its Augmented Reality (AR) and Virtual Reality (VR) tools, which create realistic, interactive environments where you can practice conversations.

You can talk to a CGI chatbot, place animated objects in your surroundings, and practice dialogues in simulated real-world situations like a restaurant or airport.

These features enhance speaking skills in a way that traditional apps cannot.

3. Career-Specific Language Courses

Unlike Duolingo, Mondly offers job-specific courses for fields like marketing, healthcare, finance, and customer service.

This makes it an excellent choice for professionals who need language skills for work.

4. Engaging and Well-Designed User Interface

Mondly’s visually appealing interface makes learning enjoyable. It provides a map-based system to track progress and organizes lessons based on real-life situations like shopping, dining, or travel.

5. Speech Recognition and Speaking Practice

Mondly’s speech recognition technology helps users practice pronunciation and speaking fluency.

While Duolingo includes speaking exercises, Mondly’s conversational approach and chatbot provide a more natural speaking experience.

6. Large Language Selection

Mondly offers 41 languages and allows learners to use any language as a base, meaning you can learn French using Spanish instead of English. This flexibility makes it great for multilingual learners.

Why You Should Choose Duolingo?

1. Completely Free Learning Model

Duolingo is one of the only language-learning apps that offers full access for free.

While there is a paid version (Super Duolingo) for an ad-free experience and offline learning, the free version still provides everything you need to learn a language.

2. Strong Grammar Foundation

Unlike Mondly, which focuses more on conversational phrases, Duolingo teaches grammar from the beginning.

It introduces basic sentence structures first, then moves on to adjectives, verbs, tenses, and sentence formation. This makes Duolingo the better choice for learners who want a strong grammar foundation.

3. Fun and Gamified Learning Experience

Duolingo turns language learning into a game, making it more engaging and motivating.

Users earn experience points (XP), complete daily challenges, and compete with friends on leaderboards. The app’s interactive animations and rewards system make learning fun and addictive.

4. Variety of Practice Drills

Each lesson includes multiple types of exercises, such as listening, translation, matching words, and pronunciation tests.

This diverse learning approach helps reinforce vocabulary and grammar in different ways, keeping lessons interesting.

5. Large Language Selection, Including Fictional Languages

Duolingo offers over 40 languages, including fictional ones like Klingon, Valyrian, and Navajo. It also provides courses for non-English speakers, making it one of the most accessible language apps worldwide.

6. Repetition for Better Retention

If you answer a question incorrectly, Duolingo repeats the question later to reinforce learning.

This spaced repetition system helps with long-term memory and ensures users don’t forget what they’ve learned.

Actually, both of them quite have a practical approach towards teaching but if I am asked, I would suggest Mondly over Duolingo for learning relevant and useful content.
