Know your night. Own your morning. NightCurve helps you see your drinking clearly — as it happens, and over time — so you can make more mindful choices. For informational and awareness purposes only. Through the night, watch your estimated Hangover Risk and NightCurve score rise and fall live on your Lock Screen and Apple Watch. The morning after — and every day in between — see the bigger picture: which days you drank, which you didn't, and what it all adds up to. KEY FEATURES: • Today's plan: Before you go out, see tomorrow's hangover risk for every drink — then choose where you'll stop. Takes 15 seconds. • Stop alert (free, always): When another drink could tip the night, NightCurve gives you a heads-up on your iPhone, Lock Screen and Apple Watch — in your own words: switch to zero, get home with someone, or call it a night. • Live Hangover Risk: Watch your estimated risk change as your session progresses — a clear nudge to know when to slow down or switch to water. • Nightly Journal: A month calendar of your drinking, day by day. Dry days and drinking days, mapped at a glance. • Alcohol-Free Days: See how many days a month you go alcohol-free — framed as your impact, never a rigid sobriety streak. • Trends & Insights: Weekly and monthly patterns — how much you drink, when, and what you reach for most. • Your Body & Alcohol: Connect Apple Health to see how drinking moves your HRV, resting heart rate and sleep, measured against your own baseline — a single night and the long-term trend. • Alcohol Footprint: Calories from alcohol, hours of fat-burning put on hold, and what a year at this pace adds up to — honest energy equivalents, never weight predictions. • Weekly Report: A Monday recap of your dry days and how your body recovered. • Apple Watch & Live Activities: Log drinks and check your status from your wrist and Lock Screen — discreet and always accessible. • Private by Design: Your data is yours. No accounts, no ads, no third-party servers — with optional private iCloud sync across your own devices. UPGRADE TO NIGHTCURVE PRO Unlock the full picture: complete Journal history and past months, weekly & monthly trends, your body's response via Apple Health (HRV, resting heart rate, sleep), the full Alcohol Footprint, plus Apple Watch and Live Activities. Available via flexible subscriptions. Disclaimer: NightCurve is for informational and awareness purposes only. It is not a medical device and is not approved by any health regulatory authority.
