Choose a focus interval that fits your work

People and tasks differ. NotchDock provides Timer presets and adjustable durations; it does not include a dedicated “Ultradian Protocol” preset.

Choose a focus interval that fits your work

Select a preset or adjust the focus and break durations in Timer Settings, then change the interval if it does not suit your work.

This page is practical timer guidance, not medical or cognitive-science advice.

For current product details, see the NotchDock focus timer feature guide.

NotchDock is currently free during beta and requires macOS 14 or newer.
