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. Your name never shared, and your data is never sold. Without AI, your plan is built on your device. DrowZe Pro Unlock AI sleep plans, sleep debt, full recovery plans at $29.99/year.

Verdict
The clearest difference is ads: CalmySleep at none against DrowZe's shown. CalmySleep also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price, update cadence and in-app purchases there is nothing between them.
