Set limits that fit your life

A useful limit is one you actually recognise as your own. KATER ZERRO lets you select a reference value or set personal alcohol limits for a day, week or month.

When you want a nudge, turn on local notifications for the first time a selected limit is crossed. The notification gives you a clear snapshot of the period and the amount over your chosen threshold.

The limit also becomes a reference line in your trends, which makes it easier to see your own numbers in context. Change it as your circumstances or goals change; it is there to support reflection, not to police you.

These values are not medical recommendations, and KATER ZERRO does not diagnose or judge. They are simply a way to make the boundaries you care about visible in the same place as your drinking history.
