Question 1

How is ShiftNight different from Sleep Cycle?

Accepted Answer

Sleep Cycle is a general sleep tracker designed for people with regular bedtimes. ShiftNight is built specifically for shift workers. It understands rotating schedules, plans naps around 12-hour shifts, and times caffeine cutoffs based on when you actually sleep, not when the sun goes down.

Question 2

Is ShiftNight better than Timeshifter for nurses?

Accepted Answer

Timeshifter focuses on jet lag and general shift adaptation. ShiftNight is purpose-built for shift schedules like 7p-7a and 11p-7a. It includes a visual shift-and-sleep timeline, weekly sleep bank tracking, and works without an Apple Watch.

Question 3

Do I need an Apple Watch to use ShiftNight?

Accepted Answer

No, but it helps. ShiftNight works fully on iPhone. If you have an Apple Watch, it pulls in heart rate and sleep stage data for more accurate analytics and smarter sleep zone recommendations. Oura Ring integration is coming soon.

Question 4

What makes ShiftNight different from generic sleep apps?

Accepted Answer

Generic sleep apps assume you sleep at night and wake in the morning. ShiftNight starts from the reality that you might get home at 7 AM and need to sleep through the day. Every feature, from nap planning to caffeine timing, is designed around that.
