## What is Kerf?

Kerf is a calm home for your daily routines. See what is waiting for you today, check off activities and build habits at your own pace.

Schedule routines daily, on selected weekdays, monthly, yearly, once, or several times within a time window. Organise routines by category and set local reminders at times that fit your day.

Your routines and progress are stored locally and sync privately through your personal iCloud account. App settings and notification permissions stay on each device. Kerf has no account or server of its own for your routines, and contains no tracking, analytics or advertising.

Create up to three routines for free. Kerf Plus unlocks unlimited routines through a monthly or yearly auto-renewing subscription. Restore purchases in the app and manage or cancel your subscription through your Apple account.
