Cold Shower Timer vs PlungeLab

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.
