Offer a managed logging service in which customers send meal photos and short notes through SMS^?, and trained reviewers produce an editable calorie and macro entry using portion references and ingredient follow-up questions. Begin with a narrow customer segment, such as recreational strength athletes who need consistent macro records but do not require clinical nutrition care. Deliver a verified daily log and weekly export, then productize repeated estimation, correction, and reviewer-quality workflows as volume grows.

Photo-based calorie estimation is attracting paid users, but the signals show that inaccurate results and weak correction workflows still destroy trust. A human-in-the-loop service can provide dependable outcomes immediately while collecting the structured examples needed for later productization.
