## What is KaterZerro?

You know your drinking habits. But do you know what they’re doing to you?

Find out with your own data. KaterZerro compares days with and without alcohol and shows you the difference in sleep, heart rate, and recovery using your Apple Health data.

Everyone knows Dry January and Sober October. But this year could have more than two alcohol-free months. Start your own challenge anytime, or simply keep an eye on how much you drink.
