What this feature does

Feast starts with a photo so logging a mixed meal does not require finding every component before you can begin. The analysis is an estimate, not a measurement, and the useful next step is to inspect it.

Why it can be useful

Photo-first capture is most valuable when it reduces the blank-page problem while leaving room for the person who ate the meal to add context the image cannot contain.

A careful workflow

Use the feature as a reviewable part of your record.

  • Photograph the full meal in clear light.
  • Add another view when ingredients overlap or height matters.
  • Review the identified foods, portions, and preparation assumptions before relying on the totals.

Limits to keep visible

Convenience and analytical detail do not remove uncertainty.

  • A photo cannot directly measure weight or reveal every ingredient.
  • Oil, sauces, fillings, and recipes can materially change an estimate.

Limits and cautions

  • A photo cannot directly measure weight or reveal every ingredient.
  • Oil, sauces, fillings, and recipes can materially change an estimate.
  • Features and plan availability can change; confirm the current in-app experience before making a purchase decision.
