Apple Health

BodyComp reads Apple Health, read-only, so your scale, workouts, burn and sleep arrive from whatever app or device recorded them.

What BodyComp reads

Apple Health dataUsed for
Body fat %, body mass, lean body massThe Body tab, your plan and trends
Height, date of birth, biological sexYour profile, only when you tap Fill from Apple Health
Active and basal energyBurn, for your energy balance
Heart rate, resting heart rateHeart-rate zones and recovery
Steps; walking, running, cycling and swimming distanceActivity and cardio
Workouts, and workout effort (iOS 18 and later)The Workout tab
SleepSleep on Charts and the recovery card
Blood glucoseOnly if you turn on glucose tracking
Workout routesThe map on an outdoor workout. Asked for only when you first tap Show route, then read each time you open one. Apple Maps loads images of the area; the route itself isn't stored, synced or sent

BodyComp never asks to write to Apple Health, and cannot. Garmin Connect and other apps that write to Apple Health reach BodyComp this way.

Where it goes

Most of it is read each time a screen needs it and isn't copied. 7 things are kept with your log, on your phone and in your own iCloud: profile fields you import, a scale reading you exclude, links between your workouts and Health's, a weekly review's saved summary, heart-rate zone minutes, your check records, and your plan's maintenance figure. One more copy stays on your phone only and never syncs: each finished day's whole-day burn and weigh-in, saved with that day's Diet score record.

2 AI features send figures derived from Apple Health when you run them: the weekly review (body composition, burn, sleep and workouts) and the goal check (body composition and a maintenance figure). They go through our server, which keeps no copy, to Anthropic. Glucose never goes to any AI.

What never happens

Turn it off

  1. On your iPhone: Settings → Privacy & Security → Health → BodyComp. Turn off any type, or all of them. BodyComp stops reading at once.
  2. What BodyComp already kept stays in your log until you delete it: in BodyComp, Settings → Storage → Delete Everything I've Logged.
