The problem

Every sleep app tells you to “establish a consistent bedtime.”

That advice is useless when you're finishing a 12-hour night shift at 7 AM.Calm, Headspace, Apple Sleep — they were all designed for 9-to-5 schedules. They don't know whether you're going to bed at 10 PM or 10 AM. They can't calculate your sleep window around your next shift. They have no idea you even work nights.

DrowZe does. Put in your shift schedule — nights, days, rotations, 24/48 — and every recommendation, bedtime, and wind-down session is calculated around your reality.

Other sleep apps say
"Set a consistent bedtime of 10:00 PM every night."
DrowZe knows
"Your shift ends at 8 AM. Sleep by 10 AM. Wake by 6 PM before your next shift Thursday."
Other apps say
"You're going to bed too late. Try to sleep earlier."
DrowZe knows
"9 AM is exactly right for your rotation. Day Sleep mode active — block the light, silence everything."
Built different

Six things no other sleep app can do

01
Live mode intelligence
The home screen knows if you're on shift, approaching bedtime, or winding down. Every recommendation changes in real time based on your actual position in the shift cycle — not a generic clock.
02
Shift-aware bedtimes
Enter your shift schedule — Panama, DuPont, 24/48, or custom — and DrowZe computes the exact bedtime window for every shift. Not "aim for 8 hours." Your specific window, tonight.
03
Sleep debt tracker
Shift work steals hours. See exactly how many. The debt meter shows your rolling deficit and a concrete day-by-day recovery plan that accounts for upcoming shifts. Numbers, not vague advice.
04
Pre-shift nap optimizer
A 20-minute nap 3 hours before a night shift is proven to extend alertness by 2–3 hours. DrowZe calculates your optimal nap window and guides you through it with a timed session.
05
Wind-down sessions
Guided audio sessions written for shift workers — not yoga studios. "Post-night shift decompression." "Day-sleep preparation." Words that make sense at 8 AM when you've just finished a 12-hour shift.
06
Day-sleep mode
When your bedtime falls between 5 AM and 3 PM, DrowZe activates day-sleep mode — specific tips for blocking light, silencing morning noise, and using the urban noise masker soundscape. The world is starting. You're going to sleep.
Always aware

Five states. The app knows which one you're in.

On shift
During your shift
Shows time remaining, your next bedtime, and current sleep debt. The nap optimizer tells you the optimal pre-next-shift nap window before you leave work.
Pre-shift
3 hours before your shift
Surfaces the nap optimizer as the primary CTA. A 20-minute nap now is the single best thing you can do for the hours ahead.
Wind down soon
90 minutes before bedtime
Suggests a wind-down session. The featured soundscape adapts — urban noise masker if you're sleeping during the day, brown noise for night.
Sleeping
During your sleep window
Quiet mode. Timer shows when to wake. Audio continues in background. No disruptions unless you've set a wake alarm.
Awake
Default — between everything
Shows your next sleep window countdown, sleep debt summary, and upcoming shift. Everything you need to plan your day around your schedule.
