Yes, starting with app version v263, you can choose how your day-view report is displayed—either from midnight to midnight or starting with your child’s day-start time.
You can get to Report Settings from the Reports tab. Tap on the settings icon in the top-right corner of the screen.
In Report Settings, the first option is “Day-view display.
Choose “Midnight” when you want to see all activities from midnight to midnight. This shows feeding, diaper, and other tracking totals (except sleep) based on a 24-hour calendar day.
Or pick "Day start time" to view activities based on when your baby typically begins their day and goes to bed for the night, based on the schedule you set in your child's profile.
