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.

Finally, a sleep app built for shift workers. Regular sleep apps assume you sleep at night. SleepShift doesn't. Whether you work nights, evenings, or rotating shifts — SleepShift calculates your optimal sleep window based on YOUR actual schedule. HOW IT WORKS: 1. Enter your shift pattern (day, evening, night, or custom hours) 2. Set your rotation (e.g., 4 days on, 4 days off) 3. Get personalized sleep recommendations every day WHAT YOU GET: - Optimal sleep windows calculated for each shift - Home screen and lock screen widgets — your next wind-down, bedtime and wake time at a glance - A Live Activity that follows your window on the lock screen and Dynamic Island - Light exposure guide — when to seek or avoid bright light - Wind-down and bedtime reminders, scheduled days ahead - Caffeine cutoff and melatonin timing - Pre-shift nap recommendations for night workers - Sleep imported automatically from Apple Health — rate a night with one tap - Trends across your shifts, with plain-language insights - Edit any single day: swap a shift, take one off, pick up an extra BUILT FOR: - Nurses and healthcare workers - Factory and warehouse workers - Pilots and flight attendants - Police and emergency responders - Truck drivers - Anyone working non-traditional hours THE SCIENCE: SleepShift uses circadian rhythm research to calculate when your body is best prepared for sleep based on your shift end time. Night shift workers get specific guidance on light avoidance, sunglasses timing, and room darkening. Rotating shift workers get transition-day plans when switching between day and night shifts. And because no real roster is a perfect rotation, you can change any single day without touching your pattern.

Verdict
The clearest difference is ads: SleepShift at none against DrowZe's shown. DrowZe's advantage is update cadence (weekly vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
