"We can see a child in the office at virtually any age -- six months, a year, two years, five years -- and we can make projections," said Dr. John Herzenberg, Sinai Hospital of Baltimore.
It's called the Multiplier App and it has 10 years of science behind it. Sinai Hospital originally designed it for other pediatricians who deal with kids with birth defects like short arms and legs. But the free app can be used by anyone.
The app itself is easy: Just put in your child's age and height.
In case you're wondering, the average height for a woman is 5 feet 4 inches tall; for a man it's 5 feet 10 inches.
Dr. Herzenberg says parents can expect accuracy of predicting height to within 1.5 inches. The best accuracy can be found when a child turns 8.
The Multiplier App is available for free on your iPad, iPhone or Android device.
