  • Pros: 80+ nutrients per food, accurate per-food data, strong free tier.

  • Pros: adaptive expenditure, weekly target tightening, strong macros math.
  • Cons: manual entry; no photo logging; small food database compared to MyFitnessPal.

  • Pros: structured coaching, evidence-based.
  • Cons: slow (3.1 s median); no barcode; limited food database.
  • Pricing: paid.
