LeanSignal

About

Your weight changed. But did your body composition? LeanSignal helps you understand what your measurements actually mean. Instead of reacting to a single weigh-in, it looks across time and supporting measurements to separate meaningful patterns from normal day-to-day noise. WHAT LEANSIGNAL HELPS YOU ANSWER • Is this change likely meaningful, or could it be water and normal variation? • Are weight and body-composition measurements telling the same story? • Is your current goal phase moving in the intended direction? • Is progress continuing, holding steady, or beginning to plateau? • Which measurement would be most useful next? UNDERSTAND THE SIGNAL LeanSignal’s Signal Score explains how strongly your recent data supports a genuine pattern. It considers measurement coverage, consistency, recency, and agreement between supporting signals before using stronger language. Every new check-in receives a clear response—even when there is not yet enough information to determine a reliable trend. MORE THAN A WEIGHT GRAPH • Quick check-ins for everyday scale readings • Full check-ins for tape and skinfold measurements • Optional read-only Apple Health import through HealthKit • Plain-language weekly reports • Weight, waist, body-fat, lean-mass, and caliper trends • Personal baselines and goal phases • Cautious forecasts and milestone estimates • Multi-method body-composition working ranges • Progress photos and DEXA reference calibration • PDF summaries, CSV reports, and complete data backup • Optional Face ID or device-passcode protection PRIVATE BY DESIGN LeanSignal requires no account and contains no advertising or third-party analytics. Your measurements and photos remain stored privately on your device. Apple Health access through HealthKit is optional and read-only, and LeanSignal imports only the information you choose to share. LeanSignal provides informational estimates and trend guidance. It is not a medical device and does not provide medical advice or clinical measurements. WHAT’S NEW — VERSION 1.0.0, BUILD 21 New: clearer HealthKit transparency and richer measurement review. • HealthKit functionality is now identified before authorization and permanently in Settings. • Apple Health imports are explicitly explained as read-only; LeanSignal does not write measurements or estimates back to Health. • The dashboard now provides a specific latest-check-in receipt with review, edit, and delete access. • Measurement Story adds noise-aware body-map comparisons and measurement relationships. • Additional polish and reliability improvements throughout the app.
