To configure the Open MacroFactor complication:
Navigate to the food timeline.
Scroll down past Tomorrow until the settings appear.
Under Complications, tap Open MacroFactor.
From this screen, you can configure whether your watch app opens “To log food, water, or weight”, “To the timeline”, or “To where I was”.
If you’d like to set which complications appear on your Apple Watch face, you’ll need to adjust them through the watch face settings. Below are the steps for setting up MacroFactor complications:
With the watch face showing, touch and hold the display, then tap Edit.
Swipe left all the way to the end. If the face supports complications, they’ll be shown on the last screen.
Tap a complication to select it, then turn the Digital Crown to find MacroFactor.
When you’re finished selecting the preferred complication, press the Digital Crown to save your changes, then tap the face to switch to it.
You can read more about customizing complications on Apple’s support page.
