It takes 40,000 words to be fluent in a language. Most language apps leave you at 5,000 or less. Instead of leaving your vocab in a chat with an LLM, save them here. TONGUES is the most comprehensive language app available, including every language and for the first time, every dialect. Acquire vocabulary by recording everyday conversations, generating lists based on your favorite topics with AI, or through your camera. Study with FSRS flashcards, audio playlists, generated stories and conversations, and home/lock screen widgets. Whereas most language apps limit you on the vocabulary you are able to acquire, spending up to a few months with colors, farm animals, and basic foods and greetings, TONGUES gives you vocabulary related to you profession first, slang, or any other interests and queries you might have. ______ TONGUES Pick a word. Any word. Most language apps hand you the same tired curriculum — colors, farm animals, "the boy eats an apple." TONGUES does the opposite. You choose what you learn, starting with the words you already care about: the jargon from your job, the slang from your hobbies, that phrase you've been dying to drop at a dinner party. Learn vocabulary that's actually relevant to your life, not a textbook's Start from your profession, your hobbies, your obsessions Give elaborate prompts and get lessons tailored to them Study what sticks, because you picked it. Studying a language should feel like learning to say the things you want to say. With TONGUES, it finally does. Download Tongues and pick your first word. EVERY LANGUAGE AND DIALECT TONGUES features every single language and dialect varying degrees. It is on average 90% accurate depending on how rare the language and dialect is. AUDIO PLAYLISTS With TONGUES, everything is automatically an audio playlist. Every word that you encounter on vacation, during a conversation, or found in an artifact, can be read out loud using state-of-the-art voice models. For commonly used language, ElevenLabs is used, and for rare languages, Forvo is used. ARTIFACTS With TONGUES, you can generate artifacts which are conversations stories that can be read out loud. You can generate their prequels and sequels while testing your reading comprehension for them. CONVERSATIONS When conversing with the AI, get valid responses in real time. Break down grammatical structures coming from the chat, and save words you don't understand back to your flashcard deck. TONGUES remains the only true language learning application that harnesses top frontier models

Verdict
Rosetta Stone Sapphire and TONGUES both sit at 4.6 stars, but that hides the real split: 100% of TONGUES's written reviews are positive against 29% of Rosetta Stone Sapphire's. TONGUES also leads on update cadence (every 3 days vs every 2 weeks). Rosetta Stone Sapphire's advantage is ratings volume (2.2K vs 5) and iOS requirement (16.4 vs 26.6). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Rosetta Stone Sapphire sells 1 in-app purchase, starting at $19.99 per month and TONGUES sells 6 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

Rosetta Stone Sapphire ships an update every 2 weeks, TONGUES every 3 days. The most recent releases landed on November 9, 2026 and October 31, 2026 respectively.
