Hub
Breathing for Calm
Slow the cycle. Keep the tool. These timers are for a structured pause — not a meditation course.
Hub
Breathing for Focus
A short numbered reset, then back to the task. Not a productivity course.
Hub
Breathing for Sleep
Evening patterns with a longer default and a darker screen on the sleep timer. Still just a timer.
Hub
Breathing for Sport
Before, after, and between efforts. Numbered cycles — not a training plan.
