German, English, Korean & more

A drink log is easier to keep when the app speaks your language. KATER ZERRO is available in German, English and Korean across the drink logger, trends and settings.

Dates, amounts, buttons and explanations stay in the same language, so you can add a drink or read a trend without translating a setting first.

Your entries, favourites and Apple Health permissions stay the same in every language, whether you use KATER ZERRO in Berlin, Busan or somewhere in between.

Language support helps in ordinary moments: adding a beer, marking a Dry Day or reading a chart. More languages are planned for future updates.
