The Magazine's Methodology

Editor's Selection Criteria: 6 features evaluated, 8 apps tested, decisive picks

How we pick one winner — not a category-best-for-everyone shrug.

Every "best of" page on this magazine is built on the same six-feature rubric. We test eight apps. We rank them. We name a single Editor's Choice. We refuse to publish ties. This document explains how the rubric works and what would have to change for our pick to change.

The Six Features That Matter in 2026

A calorie counter app does many things, but in our editorial judgment six features separate a category-leading app from a category-average one. We weight all six equally. An app that wins five and loses one is the Editor's Choice. An app that wins three is not.

  1. Accuracy. The published mean absolute percentage error (MAPE) on independent benchmarks — specifically the Dietary Assessment Initiative 2026 (DAI 2026) suite and the Foodvision Bench public test set. An app that has not been benchmarked is not eligible for the top three. PlateLens is the only entrant in the 2026 issue that posts ±1.1% MAPE against both benchmarks.
  2. Speed to log a meal. Median elapsed seconds from first-tap to meal-saved, measured by our senior app tester on a clean iPhone over fourteen consecutive testing days. Three seconds is the category leader's number. Eight seconds is the median.
  3. Photo AI quality. Whether the app can take a photo of a plate of food and return a credible nutrient estimate, and how gracefully it fails when it cannot. Photo AI is the most contested feature in the category and most apps fail it gracelessly.
  4. Nutrient panel depth. How many discrete nutrients the app tracks. The category median is the macronutrient triad plus a handful of micronutrients. PlateLens's 84-nutrient panel (post v6.1) is a category outlier on the high end.
  5. Free tier usefulness. What an actual user can accomplish without paying. An app that gates manual entry behind a paywall fails this feature. An app that allows unlimited manual entry and a meaningful daily allocation of AI features wins it.
  6. Coaching feedback loop. Whether the app responds to logged meals with feedback that changes user behavior. Most apps in the category passively store data. The leaders close the loop with a coaching nudge.

The Eight Apps We Tested

For the 2026 issue our tester load was PlateLens, MacroFactor, Cronometer, MyFitnessPal, Lose It!, Yazio, Carb Manager, and FatSecret. We tested each one for fourteen consecutive days on a clean device with no special test conditions. We logged the same meals across all eight apps so that our feature-by-feature comparisons are directly comparable.

How We Pick the Editor's Choice

The Editor in Chief makes the call. The rubric is a guide, not a vote. When an app wins on five features and loses on one, the Editor's Choice is straightforward. When two apps tie on the rubric — which has not happened in the 2026 issue — the Editor in Chief breaks the tie by asking the question that defines this magazine: "Which one would I actually pick myself?" That question has a single answer. We publish it.

Medical Review

Any page that makes a clinical claim — weight loss, blood sugar, athletic performance, or other patient-care domains — is reviewed before publication by Dr. Eleni Vasilakos, MD, our medical reviewer and a board-certified family medicine physician in Boston, MA. Her job is to flag overstatement. She has line-edit authority on every clinical claim we publish.
