How the app works
The Sleep Cycle app for Apple Watch is a standalone app that can wake you up during a light sleep phase.
The app works by tracking your sleep patterns and using an intelligent alarm clock to wake you up during a light sleep phase. You can set an alarm for a specific time, and the app will wake you up within a 30-minute window before that time when you are in a light sleep. You can customise this window to be shorter, reducing it to 10 minutes.
The app syncs all of its data directly to the Health app on your iPhone, so you can view your sleep analysis there.
The Sleep Cycle app is a popular sleep-tracking application that was first released for Apple Watch in 2018 but was discontinued due to "restrictions" in iOS. The new version of the app is completely standalone and does not require any interaction with your phone.

How to customise the wake-up phase
The Sleep Cycle app for Apple Watch can wake you up during a light sleep phase, which is said to leave you feeling more refreshed than if you were woken during a deep sleep. You can customise the wake-up phase by setting a window of time in which you would like to be woken up. For example, if you set an alarm for 5 a.m., Sleep Cycle will wake you up at some point between 4:30 a.m. and 5 a.m., depending on when you are in a light sleep. You can reduce the wake-up window from 30 minutes to 10 minutes. You can set the alarm on your watch, and it will sync all of its data directly to the Health app on your iPhone.
