Fast, focused, and completely private.

The idea behind Kerf

One notch a day

A kerf is the small cut a blade leaves in wood. On its own, almost nothing. But notch after notch, day after day, a shape appears – one that could never have become anything else.

That is the spirit of Kerf. No grand promises, no loud streaks or badges. A quiet place to mark one small cut each day – and to look back, weeks later, at what quietly grew.

Flexible where it matters.

Build routines that fit real life, not the other way around.

Every kind of schedule

Plan a routine once, daily, on selected weekdays, weekly, monthly or yearly.

More than one time

Add multiple times to one routine, without creating duplicate routines.

Repeating time windows

Repeat a routine within a time window at an interval you choose.

Today at a glance

See which routines are waiting for you today – and which you've already ticked off.

Private iCloud sync

Routines and progress can sync through your private iCloud account with CloudKit.

Private by design

No account, tracking, ads or analytics. Kerf does use Apple services for sync and purchases.
