How to Choose the Right Language-Learning App

Choosing the right language-learning app depends on your learning style, goals, budget, and the language you want to study. Whether you're comparing Babbel vs. Duolingo or looking for the best app to learn Spanish (or another language), here’s what to consider:

Learning Preferences

Think about how you learn best.

  • Babbel offers structured lessons with guided grammar tips, and real-world dialogue.

  • Duolingo is gamified and habit-forming.

  • Rosetta Stone uses a visual, immersive method.

  • Pimsleur is audio-based.

  • Speak focuses on pronunciation and speaking drills.

Goals

Before choosing a language-learning app, it’s worth asking: What’s your actual goal? Whether you’re planning a trip, building your career, or reconnecting with your heritage, any effective comparison of language-learning platforms should begin with your personal goals in mind.

Travel and Real-Life Use

If you're learning for travel, relocation, or day-to-day communication, prioritize apps that offer speaking practice, listening comprehension, and real-life conversation scenarios. For example, Babbel teaches phrases like “I’d like a coffee” or “Where’s the nearest train station?” early in the beginner track—exactly what you’ll need in real-world situations.

Fluency and Long-Term Growth

If your goal is to become conversational or fluent, look for a platform with a clear curriculum, grammar support, and progress tracking. Apps like Babbel and Pimsleur help build skills over time with structured lessons and review systems. Babbel’s CEFR-aligned courses (A1–B2) make it easy to measure your growth.

Professional Development

For career advancement, choose a program that helps with practical communication—writing emails, taking meetings, or preparing for certifications. Babbel offers focused business topics in select languages and strong spelling and comprehension support.

Just for Fun

If your goal is casual learning or building a daily habit, a free language-learning app like Duolingo may be a good place to start. It’s great for vocabulary exposure and motivation through gamified features, though it may not offer the depth needed for serious progress.

Languages Offered

Make sure the app supports the language you want to learn. Speak specializes in teaching English to non-native English speakers. Babbel offers 14 languages, with courses tailored to your native language—so a Spanish speaker learning French gets a different experience than an English speaker would.

Duolingo offers over 40 languages, including pop culture conlangs (Klingon) and less common learning languages like Hawaiian. Rosetta Stone covers 24 languages using the same immersive method across the board. Pimsleur teaches 50+ languages through an audio-based format focused on speaking and listening.
