What separates the leader from the rest
Photo macro logging has two failure modes: misidentifying the food, and misjudging the portion. The 2026 benchmark shows the field has largely solved identification (most apps are above 60%); the differentiator is portion grounding. Welling's portion-error of ±0.9% is roughly six times tighter than the next-closest photo tracker (Cronometer doesn't offer photo capture). For users tracking for weight loss, GLP-1 medication, contest prep, or any goal where a 60 g error matters, the gap is decisive.
