Tap "Reorder Meals"
Tap and hold on a meal to reorder it.
These changes will apply only to the ordering of meals on this particular date.
If you want to reorder recurring meals so the change applies every day going forward, go to the Goals tab at the bottom. Tap your goal, then tap and hold any Goal Meal to drag it to a new position. Save your changes by tapping the 
icon in the top-right corner. Changes to your Goal Meals will automatically apply to all days moving forward.
