How we tested MacroFactor

How we tested MacroFactor for macro tracking accuracy

We ran MacroFactor through the same protocol we use for every app on this site: 22,400 weighed reference meals drawn from our 22,400-meal master set, photographed across iPhone 16 Pro, Pixel 9 Pro, Galaxy S25 Ultra, OnePlus 13, and iPhone 14 at top-down and 45° angles, under both controlled studio lighting and uncontrolled kitchen lighting. Every photo was logged through MacroFactor's primary capture flow. Identification and portion estimates were compared to gram-weighed ground truth and macronutrient data from USDA FoodData Central, McCance & Widdowson, and the Japanese MEXT food composition tables.

What went into this review

  • 21 consecutive days of real-world use by two independent analysts.
  • 1,500 controlled benchmark meals across 62 cuisines.
  • Cross-checked against the same protocol used by AI Calorie Tracker and Food-Trackers.com for inter-rater consistency.
  • Subscription paid at retail, no review accounts, no comped premium.

What we deliberately excluded

  • App-store reviews and social-media sentiment.
  • Marketing claims and feature roadmaps.
  • UI polish and onboarding aesthetics (we score function, not finish).
  • Affiliate revenue. We accept none on this site for MacroFactor.
