A complication is a single, often repeated action or highly glanceable unit of information on the watchface.


The following sections describe principles to keep in mind when creating complications.


Complications are small components that typically can show one data value at a cursory glance.

Content forward

Complications are most valuable when the content that the user needs is made visible by simply raising their wrist, without needing further interaction.

Privacy first

Avoid placing sensitive information on complications so that sensitive information isn't accidentally displayed when the user raises their wrist.

Complication entry points

When tapped, complications usually open a corresponding app. However, they can also perform a self-contained action. For example, tapping the Water Count complication changes the glass count.
