Is Cronometer more accurate than CalorieScan AI?

For micronutrients, yes — Cronometer's vetted database is the most accurate consumer source. For macros on real meals, CalorieScan AI is competitive once you correct the photo, and the workflow is much faster.

Some power users do — CalorieScan AI for daily speed, Cronometer for a deep micronutrient audit once a month. We sync to Apple Health, so the data flows.
