The world’s first infinite language learning application.

Most apps top out around 6,000 words — enough to order coffee, not enough to follow a conversation that wanders. TONGUES generates vocabulary and phrases on demand at your level, so the ceiling is your curiosity, not a fixed deck.

You are not working through a canned curriculum. Tell TONGUES what you need — a language, a dialect, a job, a trip — and it builds words, phrases, and context around that. There is no last lesson.

That is the starting point. A nurse learns the ward; a traveler learns the night market. The more specific you are, the more useful every session becomes — and usefulness is what keeps people coming back.

Your memory of a word decays on a curve. FSRS models that curve and surfaces the cards you are most likely to lose, just before you would have forgotten. The study page lines those decks up first, so you never do.

Stories, news, conversations, songs, poems, and jokes generated from the exact words you are learning. You can ask for the sequel or the prequel. It is comprehensible input, not a vacuum of isolated flashcards.

Every language and dialect. No cap. Audio uses a fallback chain — ElevenLabs, then Forvo, then Apple text-to-speech, then base pronunciation — so you still hear a word when the language gets rare.

Three plans, billed monthly or yearly through the App Store. Download TONGUES, subscribe in the app, and change or cancel anytime in your Apple subscriptions.
