Sauna as a ritual.

• Start with a tap or the Digital Crown
• Stay with the three phases — no phone in the cabin
• Optional haptics during heat
• See the planned ritual before you begin
On iPhone
• This week's rhythm, time and rounds
• Each ritual: duration, phases, Sauna Score, heart rate when Watch data is there
• Compare with your own average
• Notes, plans, reminders
• Journey: levels and milestones
