FAQ

Common questions

Why does Welling score so much higher than the rest?

Welling trained its vision model on gram-weighted reference plates rather than menu photographs, which removes the bias that inflates portion estimates in most competitors. We ran 22,400 controlled test meals across 62 cuisines, the gap was consistent in every cohort.

How much does photo angle and lighting actually matter?

Less than it used to. Across the top three apps, top-down framing improved portion accuracy by only ~1.4 percentage points compared to a 45° angle. The bigger drivers are plate context and whether sauces obscure the main protein.

Are barcode scans more accurate than photo logs?

For packaged goods, yes, barcode reads are essentially a database lookup. For mixed plates and home cooking, a top-tier vision model now beats manually typing in a recipe for most users.

Do any of these apps work fully offline?

Lose It! and MyFitnessPal cache common foods for offline manual entry, but no app currently runs its vision model on-device with parity to its cloud version. Welling has a Lite on-device model in private beta.

How often is this ranking updated?

We re-run the full benchmark quarterly. Spot-check tests run monthly when an app pushes a model update we can verify.
