## Description

Night shifts flipped your sleep? Enter your roster and ShiftRhythm tells you when to sleep, when to nap, and when to seek or avoid light — today.

WHAT IT DOES
• 24-hour body-clock dial — see your estimated melatonin onset (DLMO) and biological night (CBTmin) at a glance
• Light, nap & caffeine guidance — timed to your circadian rhythm and updated as your shifts change
• Sleep score, sleep debt & recovery — last night's sleep plus HRV and resting heart rate from Apple Watch, telling you whether to push or recover
• Presets that match real rosters — Panama 2-2-3 schedule (day/night), Pitman, DuPont, Fire 48/96, 12-hour rotating shifts, plus Korean and Japanese patterns. Or build your own custom rotation
• Melatonin timing card (optional) — an informational window based on your estimated body clock. Not a recommendation to take melatonin; talk to your doctor or pharmacist first

BUILT FOR SHIFT WORKERS
Whether you're a night shift nurse, a firefighter on 48/96, a plant operator on a DuPont rotation, or a driver on a rotating roster — ShiftRhythm adapts to your schedule, not the other way around.
• Tap any calendar day to correct that day's shift
• Works from your schedule alone — no Apple Watch required
• Apple Watch app and widgets included; available in English, Spanish, Korean, and Japanese

PRIVATE BY DESIGN
• No account. No server. Your data stays on your phone.
• All circadian math runs on-device — health data never leaves your iPhone
• No ads, no tracking

PRICING
• 30-day free trial — full features, no account needed
• Then Monthly or Annual (Annual saves vs. monthly), or a one-time Lifetime purchase if you'd rather not subscribe
• Subscriptions auto-renew; cancel anytime in Settings > Apple Account > Subscriptions
