ChildArc tracks your children's growth, simply. Enter a height and a weight: ChildArc places them on reference growth charts and explains, in plain language, what they show. FREE • Height and weight plotted on the CDC growth charts from birth to age 20, and BMI from age 2 • The 3rd–97th and 25th–75th percentile bands, the median, and the percentile of every measurement • Tap a point to read its exact value, pinch to zoom, go full screen • "How to read this chart" and "What do the P values mean?" explain what a percentile is, and what it is not • A complete history, easy to correct • Inches and pounds, or centimeters and kilograms, on iPhone and iPad • A sample child to explore everything CHILDARC PLUS — ONE-TIME PURCHASE, NO SUBSCRIPTION • Charts explained: every percentile in a plain sentence ("Elliot is taller than 59% of boys the same age") and how the position changes over time • The growth rate, with its limits • Several children, each with their own color • Measurement reminders spaced according to age Plus is shared with your Family Sharing group. YOUR DATA STAYS WITH YOU No account, no ads, no trackers. Measurements are stored on your device and synced between your iPhone and iPad through your own iCloud account. The developer has no access to any of your data. GOOD TO KNOW ChildArc is a growth log, not a medical device. It does not diagnose anything and does not replace the advice of a doctor or pediatrician. On any chart, what matters is a steady curve.
