What is SnapMacro?
SnapMacro is an iPhone and Android app for logging what you eat. Add meals with a photo, a barcode scan, a food search or a manual entry, and see calories, protein, carbs and fat in one daily view.
How does photo logging work?
Photograph your plate and AI suggests the foods and portions. You review and edit them before saving. AI estimates are not exact medical or nutritional measurements.
Does SnapMacro work with Apple Health?
Yes, if you allow it. With optional Apple Health access, SnapMacro reads only your active energy and weight: active energy is added to that day's calorie budget, and your weight appears in your diary and in Stats. It only reads this data and never writes to Apple Health, and you can revoke the permission at any time in Settings.
Is my food diary private?
Usage analytics run only if you opt in, and a meal photo is sent to Anthropic for AI analysis only after you allow it in the app and choose photo logging. In the app's Privacy & data screen you can export your data as a ZIP file or delete your account immediately and permanently.
How do I get SnapMacro and manage a subscription?
Download SnapMacro from the App Store or Google Play. Subscriptions are purchased in the app. On iPhone, manage them in your Apple Account under Settings → your name → Subscriptions; on Android, manage them in Google Play.
