Decision questions for this workflow

Answer these with the current products open and your own representative use cases in view.

  • Is there one authoritative package label or several unlabelled meal components?
  • Did you enter the amount eaten rather than the label's reference serving?
  • Would scanning the package and photographing the plated amount together preserve better evidence?

Evidence boundary

The cited first-party documentation supports product behavior and positioning, not superior accuracy, behavior change, or health outcomes. No head-to-head result is asserted.

Limits and cautions

  • Competitor details are summarized from first-party materials and were not independently audited feature by feature.
  • Availability, prices, plan boundaries, and product behavior can change after the checked date.
  • Nutrition estimates from any unweighed meal should be treated as estimates.
