What is included without Plus?
Plans from today through the next seven days, calculation and source explanations, unlimited shift types, repeating rosters, calendar import, a seven-day Health comparison, wind-down, caffeine and journey-home reminders, a small widget, circular and inline lock-screen displays, Siri and Shortcuts.
How is the plan calculated?
It uses fixed rules. Settings > How plans are calculated lists all rules and current settings. Tap a block to see the calculation and sources, including Japan’s Sleep Guide 2023, Japanese Nursing Association guidance and research papers.
Why are there two options after a single night shift?
The Japanese Nursing Association describes about two hours of sleep after getting home, followed by an early bedtime. The Japanese Ministry of Health describes morning light after the shift and a longer sleep from late afternoon. Select an approach in the settings for before and after night shifts. Because staying awake until evening after a 16-hour shift is difficult, the first approach is the default. These are general reference approaches; adapt them to your circumstances.
Workplace naps are not included
Open Shifts > menu > Shift types, choose the night shift, enable a nap break and enter its start and duration.
Do I need to enter the day after a night shift?
No. The app derives it from the shift end time. A shift ending the next morning automatically marks the next day as after a night shift for display.
There are no sleep records
Check that Health contains sleep records and allow Sleep in Health > Sharing > Apps and Services > Neru Shift. An Apple Watch is not required: records written by the iPhone sleep schedule or other sleep apps can be read.
Do overlapping Watch and iPhone records count twice?
No. All asleep intervals are merged before their duration is counted.
Reminders do not arrive
Enable notifications for Neru Shift in iPhone Settings. Reminders are rescheduled for the next seven days when the app opens or shifts change. If the app has not been opened recently, the schedule may be out of date.
Moving to a new phone
Transfer app data with Quick Start or an iCloud device backup. Apple Health data is transferred separately through Health’s iCloud settings.
Plus is unavailable after purchase
Restore purchases in Settings with the Apple Account used for the purchase or a participating Family Sharing account.
Daylight saving time
Shift starts use the local wall clock. A nonexistent time advances to the next valid time; a repeated time uses its first occurrence. Duration remains elapsed time, so check schedules on clock-change days.
