PediTools: Fenton 2013 is an iPhone application designed for pediatric clinical providers. It utilizes the 2013 Fenton growth charts tailored for premature infants born betweenandweeks gestation. The app provides percentiles and Z-scores for weight, length, and head circumference based on these specific growth charts.

The Fenton 2013 preterm growth charts are a result of a systematic review and meta-analysis of population-based preterm measurements at birth from developed countries. These charts have been smoothed to ensure a seamless transition between preterm datasets and the WHO Growth Standard. The app employs LMS parameters for precise percentile and Z-score calculations, offering valuable insights for clinical decision-making.
