About
Cold Shower Timer turns every cold shower, ice bath or plunge into one clear number: how long it takes your heart rate to settle.
The cold hits as a spike. Your Apple Watch shows it live, and the moment your heart rate calms and holds steady, the watch marks it: Settled. Week by week, that moment tends to come sooner.
ON YOUR WRIST
• Big presets for wet fingers: 1, 2 or 3 minutes, or Next, which adds 15 seconds to your last session
• Live heart rate during the cold, with your peak
• The Settled moment, marked with its own haptic
• Optional breathing haptics (in 4, out 6) and a tick every 30 seconds
• Works without your phone, and saves each session to Health as a workout
ON YOUR IPHONE
• Today: the heart rate curve of your last session with the Settled marker
• Your week at a glance: sessions, cold minutes, streak
• A phone timer for days without the watch, including contrast shower rounds
COLD SHOWER PRO, ONE-TIME PURCHASE
• Adaptation: your time to Settled week by week, plus patterns such as mornings versus evenings
• Full history with water temperature
• Custom protocols and contrast shower intervals
• Watch complication and Smart Stack card
Your sessions stay on your devices. Usage analytics are off unless you turn them on.
Cold Shower Timer is a timer and a log, not medical advice. If you have a heart condition, ask your doctor before cold exposure.
