In order to start tracking your sleep with Pillow, you will first have to set up your preferred sleep mode. To do so:
Open Pillow on your iPhone or iPad
Tap on the alarm clock icon at the bottom left corner of the screen
Tap on the Plus ( + ) symbol
Select the time you would like Pillow to wake you up by tapping on the time and then use the numerical scrolls. If you do not wish to set an alarm, turn the "Alarm" switch to OFF at the top of the screen
Select whether you would like Pillow to record the sounds you make while you are asleep or not by switching the "Audio Recordings" switch ON/OFF
Select whether you wish Pillow to start playing soothing sounds to help you fall asleep when starting a new sleep session by switching the "Sleep Aid" switch ON/OFF. On that card you can also select the Sleep Aid you prefer by tapping on it, as well as the duration and the sound volume of the Sleep Aid via "Options"
Once you have decided, tap on "Done" and the preset mode will become available for use
When you feel ready to go to bed and start tracking your sleep, tap "Start" and Pillow will begin its analysis
