Poliko takes a different approach from most language learning apps. Instead of flashcards or multiple-choice quizzes, it drops you into voice conversations with an AI tutor from your very first session. You hold a button, speak in your target language, and the AI responds in under a second with corrections woven naturally into the conversation. It supports 20 languages and builds a personalized curriculum based on your level and goals.
Poliko offers 7 days of full access free. After that, Pro is $8.33/month billed yearly. For anyone frustrated by apps that teach you to read a language but not speak it, Poliko fills that gap.
Duolingo is the most downloaded language learning app in the world, and for good reason. Its gamified approach makes daily practice feel like a game, complete with streaks, leaderboards, and XP. The free tier includes the full course for 40+ languages, though you will see ads between lessons. The Max plan adds AI-powered conversation practice and explanations, but the core experience remains text and multiple-choice focused.
Busuu combines structured lessons with a community of native speakers who correct your writing exercises. The courses are built around CEFR levels (A1 through B2) and feel more like a traditional language class than a game. The free tier includes basic lessons but locks grammar units and offline access behind the Premium plan. Busuu also offers official language certificates through McGraw-Hill.
Memrise stands out for its use of video clips from native speakers. Instead of robotic audio, you hear and see real people using words and phrases in context. The app uses spaced repetition to help you retain vocabulary, and recently added an AI chatbot feature for basic conversational practice. The free tier gives you limited access to reviews, while the Pro plan unlocks the full library and all features.
LingoDeer was designed specifically for learners studying Japanese, Korean, and Chinese, though it now covers several other languages too. The lessons focus heavily on grammar explanations and writing systems, which is exactly what learners of Asian languages need. The first unit of each course is free, and the full unlock is a one-time purchase rather than a subscription.
Language Transfer is a passion project by Mihalis Eleftheriou that takes a unique audio-based approach. Each course is a series of recordings where Mihalis teaches a real student, and you pause to answer along with them. The method focuses on understanding grammar patterns through your native language rather than memorizing phrases. Every course is 100% free with no ads, no sign-up, and no premium tier.
HelloTalk connects you with native speakers of your target language who want to learn your language in return. It is a language exchange platform with built-in translation, correction, and voice message tools. The free version lets you learn one language and connect with the community, while VIP unlocks additional languages and features. It is the closest you can get to immersion without traveling.
The right app depends on your goals, your level, and how you prefer to learn. Here are the key factors to consider when comparing free language learning apps.
If your goal is fluency, prioritize apps that make you speak out loud. Reading and translating sentences builds knowledge, but it does not build the muscle memory you need for real conversations. Look for voice-based features, not just text chat.
AI-powered apps can adapt to your responses and hold open-ended conversations. Scripted apps follow a fixed path. Both have value, but AI offers more flexibility and a closer simulation of real-world language use.
Some apps offer full courses for free with ads (Duolingo), while others lock most content behind a paywall. Consider how much you can realistically learn before needing to pay, and whether the premium features are worth it for your goals.
If you are learning a widely-taught language like Spanish or French, every app has you covered. For less common languages like Turkish, Korean, or Arabic, check availability before committing to a platform.
Beginners usually benefit from a structured curriculum that guides them step by step. More advanced learners might prefer the flexibility of open-ended conversations or community exchange. Match the app to your current level.
No single app does everything well. Many successful learners use two or three apps together: one for vocabulary, one for speaking, and one for grammar. The best free language learning app is often a combination tailored to your weak spots.
