A. What it solves
Sleep apps assume you sleep at night. If you work nights, they score you against a clock you don't keep. The 90 minute nap before a 12 hour night shows up as a bad night, and the sleep you get after the shift is split across two calendar days.
AfterShift starts from your roster. A day is the gap between the end of one shift and the start of the next. Sleep and naps from Apple Health inside that gap count toward a recovery score for your next shift, and sleep debt is tracked per shift cycle.
You set your rotation once (4 on 4 off, 2-2-3, fixed nights, or your own cycle of any length) and it fills in the next 8 weeks. If your shifts are already in a calendar, it can import them from there. Caffeine cutoff, wind down and nap reminders fire relative to when your next shift starts.
The images are the widgets: next shift countdown, readiness, tonight's plan, roster, sleep graph, rhythm and sleep debt. Small up to the iOS 27 full page size, plus Lock Screen widgets and a Live Activity for naps.
B. Compared to the alternatives
* RISE ($69.99/yr) is built around a regular sleep rhythm, and its own help centre says it doesn't record daytime sleep automatically. AfterShift counts day sleep and naps without you logging them. If you keep regular hours, RISE is the more complete app.
* Timeshifter ($6.99/mo or $69.99/yr) plans light, caffeine and melatonin to move your body clock. It doesn't track sleep. If shifting your clock is the goal, use Timeshifter. AfterShift tracks how you actually recovered.
* ShiftSleep is a manual log with Apple Health import behind Pro. AfterShift reads Apple Health on the free tier.
No account, no analytics SDKs, and the data stays on the phone. The App Store label is "Data Not Collected". Health access is read only.
Automatic import needs something that writes sleep to Apple Health, like a Watch or another wearable, because an iPhone alone no longer records sleep. You can also enter sleep by hand.
C. Cost
Free: roster, sleep import, recovery score, shift-timed reminders, and the Next Shift, Readiness, Shift Plan and Roster widgets.
Pro adds the Sleep Graph, Rhythm and Sleep Debt widgets, background sync for multiple calendars, overtime tracking, and explanations written on device by Apple Intelligence.
* $3.99 / month
* $24.99 / year
* $39.99 one time, lifetime
Family Sharing on all levels.
