Editorial Policy
Source quality
We rank source quality in four tiers:
- Tier 1. Primary research with a resolvable DOI or PubMed ID; government data sources (USDA FoodData Central); raw test data published by us.
- Tier 2. Peer-reviewed secondary sources; recognized professional bodies (Academy of Nutrition and Dietetics, EFSA, NIH).
- Tier 3. App publishers' own documentation, used only to describe app behavior — not to validate claims about accuracy.
- Tier 4. Marketing material, vendor blog posts, and unverifiable third-party claims. Not cited as primary evidence.
Conflicts of interest
We accept review-unit access (free premium accounts, beta access) on the same terms as the public press list. We do not accept paid trips, hardware, or any compensation in exchange for coverage. We do not maintain affiliate accounts.
Fact-check process
Every quantitative claim in a review or comparison is linked to the underlying test record. Every external claim is linked to its source, with the source quality tier noted where useful. We do not paraphrase claims from press releases as if they were verified facts.
Re-testing cadence
Mirrors the methodology: top-tier apps quarterly, mid-tier semi-annually, vendor-release-triggered 30-day re-tests.
Editorial independence
No app publisher receives our content for pre-publication review. No app publisher has any influence over scoring, ranking, or coverage decisions. We will not delist coverage at a publisher's request — corrections are public and logged.
