Sprout Baby’s free app is one of the most polished options around. And once you’ve logged your baby’s feedings, diapers and weight, it’ll create a personalized page, letting you view all of their stats at a glance. Sprout also compiles your baby’s data into gorgeous charts, allowing you to see trends. Does your baby eat more on weekends? Or does she get sick after not sleeping enough? Sprout will help you to figure all of that out, easily.
