LoadSense: Body Battery

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.

LOADSENSE PRO

Free tells you where you are. Pro tells you where you are going.

Pro adds four things:
• The seven-day projection of the session you just configured: two curves on one chart, your week without it and the same week with it, the peak your acute:chronic ratio reaches, and the day it comes back down
• The best of those next seven days for that same session
• The on-device coach, its questions and its recommendations
• Trends past the last 30 days

Pro comes three ways: a monthly subscription, an annual subscription that opens with a 7-day free trial, or a one-time lifetime purchase for people who would rather pay once and never see a renewal.

Everything else stays free: the session simulator and its verdict, the estimated energy cost, the adaptive week grid, today's five scores, the current ratio, daily entry, the Journal, Personal Experiments, widgets and the Apple Watch companion. Your entered data is never locked. If you used LoadSense before 3.2.0, you keep every Pro feature at no cost. There is no LoadSense account, no advertising, no analytics, no tracking, no cloud dashboard and no external AI call.

YOUR DAILY HEALTH PICTURE — FREE

• 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

PERSONAL EXPERIMENTS, ON DEVICE

Choose one deliberate change for Recovery or Sleep, then compare 14 days of your usual routine with 14 days of that change. Protocols, daily check-ins and source scores stay on your device. The result describes one observed difference in your local history; it does not establish cause, effect, safety or a health benefit and is not health advice.

TRENDS AND PRIVATE JOURNAL

Explore 7-day and 28-day trends for all five metrics, free for everyone. The all-history view is part of LoadSense Pro. 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 — LOADSENSE PRO

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. The coach and its recommendations are part of LoadSense Pro; existing users keep them at no cost.

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.
