Hub

Breathing for Calm

Slow the cycle. Keep the tool. These timers are for a structured pause — not a meditation course.

Open

Hub

Breathing for Focus

A short numbered reset, then back to the task. Not a productivity course.

Open

Hub

Breathing for Sleep

Evening patterns with a longer default and a darker screen on the sleep timer. Still just a timer.

Open

Hub

Breathing for Sport

Before, after, and between efforts. Numbered cycles — not a training plan.

Open

Hub

Breathing for Work

Between meetings, at your desk, before a call — a numbered reset, then back to the screen.
