Some reviews and testimonilals:

"I’ve tried all of these growth chart apps. This one by far is the best. It’s easy to use and doesn’t limit you to only few measurements until they bug you to pay!! Highly recommended." -- Adam

"Love it! Easy to use and I don't have to go to the doctor to figure out what percentile my kid is at! And I love being able to predict my child's height." -- Carol

"I'm completely obsessed with seeing how my baby girl is growing compared to other kids. I like how I can keep track of all his growth information and compare with other kids." -- Min
