LipFlip: Speak the Language

💋 The only lip flip procedure with no needles. Possible side effects: speaking a new language with confidence.

LipFlip (formerly LinguaFlip) trains you to SPEAK languages — not just read them.

Tapping, swiping, matching words and playing games can be fun. But that builds recognition, not fluency. Real fluency lives in your brain muscles: the ability to form words and speak complete sentences without thinking.

LipFlip is built around one principle: say it out loud, every single time. That is also what makes it fast: sessions are short, and you speak from the very first card.

🎯 THE LIPFLIP METHOD

Every flashcard shows a sentence in your target language with one highlighted focus word. You read the sentence, then speak it aloud — three times. The app listens using real speech recognition and checks your pronunciation.

As you progress through three rounds, the sentence gradually blurs — leaving only the focus word visible. You must recall and speak the entire sentence from memory. This unique sentence masking technique forces active recall and builds genuine speaking fluency.
