Ododok counts every chew from the motion sensors in your AirPods

2 months ago

Your AirPods can feel you chew. The same motion sensors that track which way your head is turned can pick up the small jaw movement every bite makes. Ododok is a free iPhone app that reads that movement. While you eat, it counts each chew, live.

Your AirPods can feel you chew. The same motion sensors that track which way your head is turned can pick up the small jaw movement every bite makes. Ododok is a free iPhone app that reads that movement. While you eat, it counts each chew, live.

Finish, and you get a quick summary of the meal.

You put your AirPods in, tell Ododok you’re starting a meal, and start eating. On screen, a squirrel named Odi chews along with you, filling a bowl with acorns. When you finish, Ododok hands you a quick summary of how fast that meal went.

Finally, a number for how fast you eat

Works with the AirPods you already own.

Slowing down at meals is advice you have heard your whole life. But you finish a meal with no idea how fast you actually went. Ododok gives you a real number: how many times you chewed, and how quickly. Anyone with recent AirPods can use it.

Chewing shows up in your AirPods' motion

Chewing shows up in your AirPods’ motion.

AirPods motion sensors
the same ones that track your head for spatial audio
→
Chewing is a small, steady motion
your jaw and ear move in a rhythm the sensors feel
→
A quick warm-up
learns what your own chewing feels like
→
Each chew, counted live
straight from the motion, while you eat
No gadget in your mouth · No camera watching you · Just the AirPods you own

Here is the actual trick. Recent AirPods carry tiny motion sensors. Normally, those sensors power spatial audio, the feature that keeps sound in one spot when you turn your head. Apple also lets apps read that same motion. When you chew, your jaw and ear move in a small, steady rhythm, and the sensors feel it. So you need no gadget in your mouth and no camera watching you eat. Ododok reads the AirPods you already own. Everyone chews a little differently, so Ododok first runs a short warm-up to learn what your chewing feels like. After that, it counts each chew live, straight from the motion.

The game is what makes it stick

The game is what makes it stick.

Odi and the acorns
the squirrel collects an acorn for every chew
A meal report
see how fast that meal went, with a pace score
A daily streak
a calendar that keeps you coming back
Invite friends
slow down together
The clever part: it reuses sensors already in your AirPods, so you buy nothing new, and the app is free.

On its own, a chew counter is a novelty. So Ododok makes it a game: Odi collects acorns as you chew, and a daily streak keeps you coming back. The clever part is the detection. Ododok reuses sensors Apple already put in your AirPods, so you buy nothing new, and the app is free. The maker’s bet is that slowing down is good for you. Ododok shows you your pace.

Ododok is a free iPhone app, made by Sungho Choi. You’ll need a recent iPhone, and AirPods that carry motion sensors. That means AirPods Pro, or the third or fourth generation AirPods. Right now, it’s live only in the Korea and Japan App Stores, so most people can’t install it from their own store yet.

So the earbuds already in your ears can tell you how fast you eat. Ododok turns that into a chew count, and a game.
