INTERGROWTH vs Leaner

The INTERGROWTH-21st app allows healthcare providers and individuals alike to plot and assess size at birth for all newborns and follow the postnatal growth of preterm infants from birth until 64 weeks post-menstrual age, at which point the use of the WHO Child Growth standards is recommended. The INTERGROWTH-21st standards develop scientifically robust clinical tools to assess fetal growth and the nutritional status of newborn infants, as adjuncts to the recently produced WHO charts for children aged 0 to 5. These are now being incorporated into national and international maternal and neonatal programs.

See the trend, not the noise. Make the most of the smart scale you already own. A home body-fat scale can swing 2–4 percentage points a day on hydration alone - far more than the real change you're working for. So people give up, sure it isn't working. It usually is. You just couldn't see it. Leaner does one thing, and does it properly: it turns your noisy daily body-fat readings into a single, stable trend line - so real progress finally shows through. Why it's different • Trend over readings - the headline number is your smoothed true estimate, never a jumpy raw reading. • One metric, done right - body fat % only. No calorie logging, no macros, no weight-loss guilt. • Apple Health native - reads from any smart scale or caliper app you already use, and writes your manual entries back. Your data is never trapped. • Honest projection - a clearly-labelled estimate of when you'll hit goal at your current rate, with the uncertainty shown, not hidden. How it works Every reading goes through a smoother that tracks both your level and your direction, so it shows today's real value instead of lagging behind like a 7-day average. Skip a few days, log twice in a morning, fat-finger a reading - Leaner handles it gracefully. Free forever The smoothed trend, today's number, Apple Health sync, manual entry, your goal and projection, and CSV export - all free, no ads, ever. Leaner+ Go deeper with advanced smoothing controls, the full Journal with streaks, milestones and celebrations, Home & Lock Screen widgets, category bands and maintenance mode, and Weekly Insights - a calm Sunday recap of your week. Private by design All your data stays on your device and in Apple Health. No third-party analytics on health values. No tracking. No accounts. Download Leaner and start seeing the trend. A note on your health Leaner is a tracking and informational tool, not a medical device, and does not provide medical advice, diagnosis, or treatment. Body-fat readings and trends are estimates and should not be used to make medical decisions. Always consult a qualified healthcare professional before changing your diet, exercise, or health routine, and before acting on anything you see in the app. Terms of Use (EULA): https://leaner.health/terms Apple standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://leaner.health/privacy
