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.

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. WHY SLEEPSHIFT: - Zero apps are designed specifically for shift workers - 25 million Americans do shift work - Poor shift-work sleep is linked to serious health risks - We help you sleep better, feel better, and stay healthier Try free for 14 days. Plans start at $2.92/month (billed annually).
