Reading: your workouts count against your day
Active energy comes in from Apple Health, so a long run shows up against your day rather than leaving your numbers looking like you overate by six hundred calories.
Nothing about this requires you to use a particular watch or app. If something on your phone writes active energy to Health, AIM can read it.
Writing: your meals reach your other apps
Energy and macros from meals you logged go back out to Health, where anything else you use can pick them up. Nothing is written unless you turn it on.
Permissions are Apple's, not ours
Health access is granted per data type, in Apple's own Health app, and declining one at the prompt does not block the others — which is why the most common support question here turns out to be a single permission left off.
You can revoke any of them at any time without uninstalling AIM. Health data is never sent to the AI provider, never used for advertising, and never shared.
Questions
- Does AIM write calories to Apple Health?
- Yes, if you turn writing on. Energy and macros from the meals you log are written to Health so your other apps can read them.
- AIM isn't reading my workouts — why?
- Check Health → Sharing → Apps → AIM and make sure Active Energy is allowed. iOS grants Health permissions per data type, so it is common for one to be off while the rest are on.
- Is my health data sent to the AI?
- No. Apple Health data is never sent to the AI provider. Only the photo or description of the meal you are logging is.
