Night shift wrecked your sleep? DrowZe turns your roster into a sleep plan that moves when your shifts do — built for nurses, paramedics, and anyone on nights or rotating schedules. Most sleep apps assume you sleep at night. DrowZe starts from your shifts: when you finish, when you're back on, how long your commute is, and whether you're an early bird or a night owl. Then it tells you exactly when to sleep, nap, stop caffeine, and see light. AI SLEEP PLANS, SAFETY-CHECKED • DrowZe's recovery engine builds science-based sleep options around your shifts • With AI on (Pro), the AI coach picks the option that fits your recent sleep, sleep debt, and preferences — and explains why • The AI only chooses between options DrowZe has already checked. It never guesses your sleep times from scratch SNAP YOUR ROSTER • Take a photo or upload your work schedule — AI schedule scan pulls out every shift for you to review • Or use built-in rotations: Standard 12/12, Panama, DuPont, 24/48 paramedic, or build your own SLEEP DEBT & RECOVERY • See your sleep debt after back-to-back night shifts • Get a night-by-night recovery plan to pay it back without wrecking your days off • Recovery score shows whether you're catching up THE DAY-OF DETAILS • Pre-shift nap window reminders • Caffeine coach: when to have it, when to stop before sle • Light guidance to protect your circadian rhythm • Tonight Replan when a shift runs late or plans change WORKS WITH WHAT YOU HAVE • Reads sleep from Apple Health (read-only, optional) • Syncs shifts and sleep blocks to your calendar • Log sleep manually in seconds PRIVATE BY DEFAULT AI features are off until you turn them on.
