Widget and notifications

KATER ZERRO Home Screen widget, limit-notification setting and periodic-summary notification

The KATER ZERRO widget shows two private signals on your Home Screen: your current dry-day count and drinks logged this month.

Tap the dry-day card to review today’s entries, or the monthly total for recent trends. It is a compact view of the month, without another dashboard or account.

Choose a personal daily, weekly or monthly limit and opt in to a local notification. When a new drink first takes the period over that value, KATER ZERRO can let you know. The limit is your own reference, not medical advice.

Enable summaries for daily, weekly, monthly, quarterly or yearly views. They require Background App Refresh for KATER ZERRO in iOS Settings and prompt you to review a completed period. A daily recap can ask whether yesterday’s drinks are complete.
