Ododok reads the accelerometer inside AirPods Pro or the 3rd- and 4th-generation AirPods to count how many times your jaw moves per meal, then logs chewing speed and total eating time into a daily report. A cartoon squirrel chews alongside you and hands out collectible acorns you can compare against friends. It’s free, and — as of this writing — sold only through South Korea’s App Store, with no US listing yet.
