TongueTwister

The tongue-twister app that celebrates failure: speak up, trip over your words gloriously — and share your knot video with the world.

Anyone can speak perfectly. Failing is an art.

The knot score

0–100 points for tripping up: from “Slick” (try-hard!) to the “Gordian Knot”. The wilder your tongue stumbles, the higher your score.

Your knot as a video

Every attempt becomes a shareable vertical video: a knotted tongue, your original audio, your knot score and a cheeky AI one-liner — shared straight from the app to Instagram Reels and YouTube Shorts. Nobody shares perfect pronunciation. Your knots, they share.

Apple Intelligence on board

The AI roasts every attempt with a wink, coaches your problem sounds and writes personal tongue twisters for you — fully on-device. The AI generator needs iOS 27 and a device with Apple Intelligence.

410 classics, 10 languages

Curated, documented tongue twisters in English, German, Spanish, Portuguese (BR), French, Italian, Swedish, Danish, Norwegian and Dutch — including a tongue of the day, streaks and anecdotes for every line.

Private by design

Speech recognition runs on-device. No accounts, no tracking, no servers — your voice only leaves your device if you share your knot video (with your recording in it) on social media yourself.

Honest feedback

Accuracy, completeness and speed at a glance — plus what the app actually understood. Sometimes that's the best part of the whole attempt.

New in version 1.1

The North Sea pack: 160 new tongue twisters in Swedish, Danish, Norwegian and Dutch — 40 classics each, every one with its own anecdote. Plus bug fixes and small improvements.

Six degrees of tongue knots

From a try-hard clean run to the total surrender of articulation — where do you land on “She sells seashells”?
