KaterZerro – Alcohol Tracker & Insights
See how alcohol affects you through your own health data
How much alcohol do you actually drink? And what does it do to your body? KaterZerro helps you find out. Track your drinks, compare days with and without alcohol, and discover how drinking affects your sleep, heart rate, HRV, and recovery using your own Apple Health data. Spot drinking patterns, count alcohol-free days, start your own sober challenges, and share your achievements. Privacy first. No account, no tracking, no ads. Your health data stays on your iPhone.
Hi, Dirk here, founder of KaterZerro 👋 I’ve tracked my drinking with different apps for over 5 years, but always missed proper Apple Health integration, especially to see how alcohol affects sleep, HRV, and heart rate. Some apps even cut off stats at midnight (who stops drinking at midnight haha).
What started as a little Jupyter/Pandas side project in early 2026 turned into an iOS app.
Privacy matters with data this personal, so everything stays in Apple Health. No accounts, servers, or tracking.
The goal? The best alcohol tracker for data nerds 😅 Would love your feedback!
