One goal. No daily reset.
Calorie Arc keeps calorie progress cumulative and transparent, with local records and an optional, narrowly scoped Photo analysis.

Calorie Arc is a calm, cumulative energy journal for iPhone. Log food manually or review an optional photo estimate, see how each counted day changes one continuous journey, and keep in-progress information separate until you review and count the day.
Private by design
Calorie Arc has no account, ads, third-party analytics, or cloud sync. Your profile, Journey, Food history, weight entries, and optional Apple Health data stay on the device.
Photo analysis sends only two reduced dish photos, measurements, optional dish context, App Attest metadata, and StoreKit proof through a dedicated Cloudflare Worker to Anthropic. The app and Worker do not store the photos.
How the numbers work
Energy at rest and activity energy together give estimated energy used. Food is compared with that estimate to produce the daily balance. Only a day you review and count changes the journey.
Apple Health activity and Manual activities are added together, so both remain visible instead of one replacing the other.
Lifetime Pro, no subscription
Basic remains useful without a purchase or Apple Health. Calorie Arc Pro is an optional one-time lifetime purchase handled by Apple through StoreKit and includes Photo analysis, with up to five completed analyses per UTC day on each attested device.

Wellness scope
Calorie Arc is a general-wellness tool. It does not diagnose, treat, cure, or prevent a medical condition, does not provide medical advice, and does not guarantee a particular weight change. Its numbers are estimates, not measurements.
