Store description excerpt
Is my child growing on track? Log the numbers from a checkup or school measurement, and see the answer on a chart. Enter height and weight, and they're plotted against an official growth standard (WHO 0-23 months, CDC 2-20 years) as a smooth curve. See at a glance where your child falls within the standard -2SD to +2SD band. ■ Who this is for ・You want to log a measurement the moment you get it from a checkup or school ・You want to check regularly whether your child is tracking along the growth curve ・You've built up years of growth records and don't want to risk losing them ・You don't want your child's data stored on someone else's server ■ What's free ・Log height and weight (1 child, unlimited records) ・Growth curve chart based on the WHO/CDC international standard (height & weight) ・Automatic SD score and approximate percentile ・Record list, notes, and later edits ・Automatic backups plus file export/import (for switching devices) ■ Built to never lose your data Growth records are something you build up over years — they should never be at risk. This app protects them with three layers of defense: ・Every save is verified before it replaces the previous file (a power loss mid-write can't corrupt your data) ・Multiple daily snapshots are kept automatically ・If the data file is ever unreadable, it's automatically restored from a backup ■ What Premium unlocks (one-time purchase) ・Add siblings (a second child and beyond) ・Export records as a CSV with SD scores (handy to bring to a checkup or print) ・An estimated target height calculated from both parents' height (reference only) No subscription. Pay once, use it forever. ■ Privacy Everything you enter (your child's name, birthday, height, weight, etc.) is stored only on your device and never sent to any external server. No account registration required. ■ About the growth standard This app's growth curve and SD scores use the World Health Organization (WHO) Child Growth Standards for ages 0-23 months, connected with the CDC Growth Charts (2000) for ages 2-20 years. Because the two are based on separate research populations, there may be a slight step where they connect (24 months) — we show this as-is rather than smoothing it out. ■ Please note The figures shown are a recording and calculation aid, not a medical diagnosis or advice. If you have concerns about your child's growth, please consult a medical professional or checkup.
