Works with other trackers

Already logging drinks somewhere else? If that app syncs alcohol consumption to Apple Health, KaterZerro can show those entries alongside the drinks you log here.

External entries are labelled with their original source. They count in your day, calendar and trends, so changing apps does not have to mean starting your history from zero.

KaterZerro leaves external entries read-only. If something needs correcting, change it in the app that created it instead of risking a duplicate or a deleted record.

That keeps one shared Apple Health record useful across the trackers you choose. KaterZerro adds its own quick logging and views without taking ownership of someone else’s data.
