## What is Contrast Sauna & Cold Tracker?

Track cold plunges, sauna sessions, and complete contrast routines in one focused app.

Contrast helps you record every round, build a consistent practice, and explore personal patterns across your sessions and Apple Health data—without exaggerated wellness claims.

TRACK YOUR WAY
• Record cold plunges and sauna sessions
• Use a live timer for exact round durations
• Switch between cold and sauna during a session
• Save multi-round contrast sessions together
• Add sessions manually when you do not use the timer
• Record optional temperatures in Fahrenheit or Celsius
• Review and edit your complete session history

DISCOVER YOUR PERSONAL PATTERNS
Connect Apple Health to explore associations between your cold-plunge, sauna, and mixed sessions and:
• Sleep duration
• Resting heart rate
• Heart rate variability

Contrast compares next-day health metrics after tracked exposure with your own comparison days. These insights describe associations in your personal data and do not establish cause and effect.

BUILD CONSISTENCY
• Follow your current and longest streaks
• Review weekly and monthly activity
• Track total sessions, time, and average duration
• See separate cold-plunge and sauna totals
• Monitor your progress toward new insights

APPLE HEALTH INTEGRATION
Saved sessions can sync to Apple Health as workouts. Contrast can also read the Apple Health data you authorize for personalized insights. Health access is optional and can be managed at any time.

PRIVACY BY DESIGN
Usage analytics are disabled by default and require your explicit permission. Health information, session dates, temperatures, durations, notes, workouts, and insight results are never included in analytics.

PREMIUM INSIGHTS
Core session tracking and your first available personalized insight are accessible without Premium. Contrast Premium unlocks every available health insight through a monthly or annual auto-renewable subscription.

Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel subscriptions in your Apple Account settings.
