Watch complications
From the app’s English Help & Guide · Reference release 1.0.13
Supported provides a 'Top concern' watch complication that puts the most concerning person right on your watch face.
Four complication shapes are supported, so the complication fits whichever face you're using:
• Inline — a short status line • Circular — a single dot in a circular slot • Rectangular — name and status in a rectangle • Corner — a curved status indicator for corner-style faces
To add it, touch and hold the watch face, tap Edit, swipe left to the complications screen, tap a slot, then turn the Digital Crown to choose Supported. Press the Digital Crown to save.
The complication tells you who needs your attention most without unlocking your phone. Tap it to open the watch app for more detail.
