LeanSignal is now on the App Store

LeanSignal is live. Our private body-composition interpretation app is now available on the App Store for iPhone, bringing weight, waist, body-fat, lean-mass, skinfold, DEXA, and Apple Health measurements together in one evidence-based view.

Instead of reacting to every fluctuation, LeanSignal compares measurements across time, learns your personal baseline and ordinary measurement noise, and explains when the available evidence supports a repeatable pattern. Every check-in receives a clear response, including the early stage when there is not yet enough history for a confident interpretation.

The core experience is free: check-ins, dashboard interpretation, Signal Score, basic trends, measurement history, and CSV export. An optional one-time LeanSignal Pro purchase adds longer-term comparisons, noise-aware Measurement Story views, forecasts, milestones, advanced reports, and deeper measurement relationships. There is no subscription, account, advertising, or third-party analytics.
