LoadSense: Body Battery

See an explainable Body Battery from Apple Health and Apple Watch: energy, recovery, sleep, load and stress—processed privately on device.

What can your body handle today—and why?

LoadSense turns Apple Health and Apple Watch signals into an explainable Body Battery and daily energy budget across five views: Energy, Recovery, Sleep, Strain and physiological Stress. See what changed, what evidence is fresh, and one bounded next action without sending your health history to a server.

FREE CORE, PRIVATE BY DESIGN

The complete health experience is free. Optional tips in Settings support development and unlock nothing. There is no LoadSense account, advertising, analytics, tracking, cloud dashboard or external AI call.

YOUR DAILY HEALTH PICTURE

• Energy Bank with today's range, reserve and clear drivers • Recovery built from your available local health evidence • Sleep need, duration and debt without inventing missing values • Strain compared with a personal daily target • Physiological Stress from supported heart and movement signals • Fitness and training-load context across your workouts • CNS Tap Test retained as a quick local check

TRENDS AND PRIVATE JOURNAL

Explore 7-day, 28-day and all-history trends for all five metrics. Add configurable Journal entries stored locally, then view cautious associations only when enough history exists. Associations describe patterns, never cause, effect or prediction.

COACHING THAT STAYS LOCAL

Ask focused questions about recovery, strain, trends and Journal patterns. Deterministic answers are available on every supported device. When Apple Intelligence is available, wording may be refined on device while the facts, safety rules and actions remain fixed.

IPHONE, IPAD AND APPLE WATCH

Check your cached daily state on Apple Watch and add Energy, Recovery, Strain or Stress complications. Local widgets, App Intents and opt-in notifications use the same canonical snapshot.

YOU CONTROL THE DATA

Export a private JSON copy or delete LoadSense data from Settings. Health data remains managed by Apple Health and is never deleted by LoadSense. No extra band is required; full analysis works best with Apple Watch data.
