The easiest way to add the Pocket Informant watch complication(s) is to do the following:

1. Go to the Watch app on your iPhone device

2.  Tap on one of the faces under the My Faces section

3. Under Complications tap either the Middle or Bottom options

Note - Apple's Watch faces have a variety of complication layout options (eg, Top Left, Sub-dial Right, etc), but currently only watch faces with Middle or Bottom options will work with Pocket Informant complications
