## What is Cold Mastery?

Master the cold — one session at a time.

Cold Mastery is your guided companion for cold showers, ice baths, and cold plunges. No method dogma, no guru subscription — a precise tool that turns your intention into a daily practice.

THE COMPLETE PRACTICE ON iPHONE
  • Timer with adjustable lead-in and voice coach
  • Guided breathing exercise (Box Breathing, Power Breathing, and more) before each session
  • 3 training programs — from beginner to Cold Master
  • Streak tracking with milestones and daily goals
  • Temperature tracking for every session
  • Session history, calendar, and progress charts

WITH APPLE WATCH: MEASURED LIVE
  Wearing a Watch adds the crucial layer — in the shower, in the plunge, and in open water:
  • Direct access from the watch face — two taps and your session is running
  • Haptic countdown pulses every 15 or 30 seconds — close your eyes, focus on your body
  • Live heart rate during the session: see your cold shock response in real time
  • Recovery phase with HR recovery tracking after the cold
  • Water Lock for safe wear underwater

PROGRESS YOU CAN MEASURE  
Cold Mastery doesn't just show you how long you lasted — it shows how your body adapts:
  • Peak heart rate trend: your cold shock response decreases over weeks
  • Recovery rate: how quickly your heart rate returns after the cold
  • Endurance: from 15 seconds to Cold Master

PROGRAMS THAT CARRY YOU
  Three evidence-based training programs give your practice structure:
  • Cold Starter — your entry point with short cold showers
  • Cold Seeker — increase duration and intensity step by step
  • Cold Master — for the experienced: ice baths, plunges, and longer exposures

YOUR DATA STAYS YOURS
  • No account required — no profile, no email
  • No data sent to external servers — your sessions stay on your devices
  • Private iCloud sync between iPhone and Watch

COLD MASTERY PRO
The core features with cold showers, timer, and streak are free. Pro unlocks:

  • All session types (ice bath, cold plunge, open water)
  • Guided breathing exercise with voice coach
  • Detailed progress charts (HR trends, recovery rate)
  • Training programs

Not a medical device. Cold exposure carries risks — educate yourself and listen to your body. Not suitable for certain cardiovascular conditions, asthma, or during pregnancy. When in doubt: consult a doctor.
