Field notes
The workflow distinguishes LiDAR scans from photo estimates: LiDAR can help when the plate surface is visible, while containers, poor coverage, or unsupported phones fall back to photos. When foods are hard to distinguish, the app says it asks a question; users can also revise the gram amounts. The page lists approximate uncertainty ranges and names its nutrition-data sources, while cautioning that estimates are not medical measurements.
