Common AfterShift questions

Does AfterShift sell my health data?
No. AfterShift has no ads, no third-party trackers, no analytics SDKs, and no servers to send data to. Your sleep, nap, and shift data stay on your iPhone, because there is no account and no cloud sync. Data leaves the device only if you export or share a report yourself.
Does AfterShift sync between devices or work on iPad?
No. AfterShift runs on iPhone only, and there is no account and no iCloud sync, so your data lives on one iPhone. Deleting the app deletes that data. A Premium purchase restores on any iPhone signed in with the same Apple ID.
Do I need an Apple Watch?
No. AfterShift has no Apple Watch app and does not need one, but it does need sleep in Apple Health, and an iPhone on its own records none. An Apple Watch or any sleep app that saves to Apple Health will do. You can also log naps in the app and log sleep by asking Siri. A source that records sleep stages adds the stage detail; without it, the stage part of the scores uses neutral defaults.
Does it matter if I'm a morning person or a night owl for shift work?
Yes. Your chronotype is one of the biggest predictors of how hard rotating and night shifts will hit you. Strong morning types (larks) struggle more with permanent night shifts because their circadian system resists the phase shift; strong evening types (owls) usually adapt better to nights but pay for it on early-morning rotations. Most people sit in the middle. AfterShift does not ask you to label yourself; it works from the sleep you actually get around your shifts. If you want a formal read on yours, sleep researchers use two validated tools: the MEQ (Horne-Östberg Morningness-Eveningness Questionnaire) and the MCTQ (Munich ChronoType Questionnaire).
What is social jet lag, and does it matter for shift workers?
Social jet lag is the term sleep researchers use for the gap between your biologically preferred sleep timing and the schedule your work or social life imposes. Most people feel some of it on Monday mornings after a freer weekend. For shift workers the mechanism is the same but much larger: a permanent night-shift nurse who spends days off with a family that sleeps at night is in effect flying across time zones every weekend. AfterShift does not measure social jet lag. Its sleep-debt trend shows, cycle by cycle, whether your debt is building, stable, or recovering. Researchers use the MCTQ (Munich ChronoType Questionnaire) to quantify social jet lag if you want a formal read.
