The Delta device automatically detects and tracks your sleep when you wear your device to bed. Awww, thoughtful! We recommend wearing your device snugly – but not too tight – on your wrist while sleeping. When your body is completely at rest and you haven’t moved for a certain duration, the Delta device considers you asleep and starts recording.


You’ll find an excellent breakdown of your sleep data in the HeadUp app. Simply sync your device each morning to allow HeadUp to access the previous night’s data. Then head on over to your Dashboard and select the Sleep category:


From here, you will be able to select the “Time Asleep” tab to access your data over time.
