Sleep planner for shift workers.
ShiftRest builds a personalised sleep, nap, and caffeine plan around your work roster, so you can recover even on rotating and night shifts.
Your privacy matters. ShiftRest does not collect, store, transmit, or share any personal data. The app is designed to work entirely on your device.
None. We do not collect any personal information. Specifically:
Any information you enter — such as your work shifts, sleep preferences, and settings — is stored only on your device (and, for the home‑screen widget, in a private on‑device app group shared between the app and its widget). This data:
ShiftRest can send you local reminders (bedtime, wake‑up, caffeine cut‑off, and nap windows). These notifications are scheduled and delivered entirely on your device by iOS. Enabling them is optional, and you can turn them off at any time in the app or in the iOS Settings app.
ShiftRest works fully offline and does not make network requests to transmit your data.
ShiftRest does not knowingly collect any data from anyone, including children.
If this policy changes, the updated version will be posted on this page with a new “Last updated” date.

When contacting us, it helps to include your device model and iOS version, plus a short description of the issue and steps to reproduce it.
How does ShiftRest create my sleep plan? It uses your shift times and preferences (target sleep duration, commute time, wind‑down time, and caffeine cut‑off) to calculate a recommended main sleep window, an optional nap, and a caffeine cut‑off time for each shift.
How do I add a rotating schedule? On the Schedule tab, tap Add ▸ Rotation Pattern, define your repeating pattern (for example Day, Day, Night, Night, Off, Off), choose a start date and how many times it repeats, then tap Generate.
Why aren’t my reminders showing up? Make sure notifications are enabled for ShiftRest in Settings ▸ Notifications, and that you have upcoming shifts added. Reminders are only scheduled for future sleep windows.
The widget says “No plan” — how do I fix it? Add at least one upcoming shift in the app. The widget updates on its next refresh after your schedule changes.
Is my data backed up or synced? Your data lives on your device only. It is not synced to any server. Deleting the app removes your data.
ShiftRest provides general scheduling and lifestyle guidance to help you plan rest around shift work. It is not medical advice and is not a substitute for professional healthcare. If you have concerns about sleep, fatigue, or your health, please consult a qualified healthcare provider.
