Two different approaches
Other apps
Examples include DrinkControl, Reframe, TRY DRY, I Am Sober and Sunnyside
Depending on the app, they may focus on:
- Track drinks
- Set goals
- Follow a programme
- Coaching, community or recovery support
They can be diaries, sobriety challenges, coaching or recovery tools. These approaches suit people who want structure, support or a service alongside the drink log.
KaterZerro
- Track drinks
- Spot patterns
- Compare health data
- Understand, then decide
KaterZerro is a personal alcohol × health analytics tool. Track drinks, reveal patterns and compare them with the Apple Health data you choose to share. It shows what tends to happen in your own data instead of telling you what to do.
What makes it different
Good tracking
Drinks and dry days stay in one record. Real 07:00–07:00 days keep a 01:00 nightcap with the evening that came before it.
Apple Health
Put drinks beside the Apple Health data you choose to share, including sleep, HRV and resting heart rate. With enough recorded days, Hangover Insights compare different drink ranges with your alcohol-free baseline.
A difference is a pattern to explore, not a medical conclusion. Entries from another tracker can also appear source-labelled and read-only.
Your guidelines
Choose personal daily, weekly or monthly reference values. They add context to your own history without making decisions for you or presenting a diagnosis.
Private by design
No account, no coach reading your progress and no social profile. There is no tracking backend, and Apple Health access uses only the permissions you choose.
