## What is NightCurve?

Know your night. Own your morning. NightCurve tracks every drink through the night and gives you an estimated Hangover Risk Score in real time — so you recognize your patterns and know when to slow down. For informational and awareness purposes only.

More than a drink counter: watch your risk rise and fall live on your Lock Screen and Apple Watch, and see how water and food flatten the curve.

KEY FEATURES:

• Hangover Risk Tracking: Watch your estimated risk level change as your session progresses. Stay informed, stay mindful.
• Wellness Score: A proprietary composite score (0–100) that reflects your session load in real time. A helpful nudge to know when it might be time to switch to water.
• Apple Watch Companion: Log drinks and check your wellness score directly from your wrist — discreet and always accessible.
• Live Activities & Lock Screen: Monitor your session status and estimated recovery time right on your Lock Screen.
• Flatten The Curve: Log food and water intake to see how hydration and meals may influence your wellness and hangover risk score.
• Privacy First: All data stays on your device. No accounts, no cloud, no tracking.
