## What is Contrast?

Start your contrast therapy session in under 5 seconds. No accounts. No subscriptions. Just tap and go.

Contrast is the purpose-built timer for sauna and cold plunge practitioners. Whether you follow a Huberman protocol, Wim Hof method, or your own custom routine, Contrast keeps you on track with large, glanceable timers and automatic HealthKit integration.

SIMPLE SESSION TIMING
Tap Sauna or Cold Plunge from the home screen and your timer starts immediately. The large 96pt display is readable from across the room -- even through steam. End your session with a single tap and everything is saved automatically.

SMART CONTRAST PROTOCOLS
Choose from preset multi-phase plans or build your own:
- Quick Contrast: 15min sauna + 2min cold (17 min)
- Standard Protocol: Two rounds of sauna and cold plunge (36 min)
- Extended Session: Three full rounds for deep practice (54 min)

Plans auto-advance between phases with audio and haptic alerts so you never lose track of where you are.

AUTOMATIC HEALTH TRACKING
Every session saves to Apple Health as a Mind & Body workout with duration and estimated calories. Your contrast therapy practice appears alongside all your other health data with zero manual entry.

DESIGNED FOR WET HANDS
Giant touch targets, high-contrast colors, and no precision gestures required. Contrast works the way you actually practice -- sweaty hands and all.

SESSION HISTORY & PERSONAL RECORDS
Track every session, see your progress over time, and hit new personal records. All your data stays on your device, private by default.
