Cronometer: micronutrients, not just calories
Tracks 80-plus nutrients against a curated food database. 97,304 ratings at 4.8 — the highest in this category, and the most demanding to use.
Most calorie apps count three numbers. Cronometer counts eighty, and that single decision explains both its 4.8 rating and why it is not for everyone.
97,304 ratings — the best-scored app in this category.
What it does differently
A curated database. Entries come from lab analyses and verified sources rather than user submissions, so the numbers hold up. Crowd-sourced databases are faster to search and frequently wrong.
Micronutrients. Iron, B12, magnesium, omega-3 ratios. If a doctor told you to watch something specific, this is the app that tracks it.
What it asks
Precision. Logging takes longer because the database expects you to say which cut, which preparation, which weight.
People who want a rough daily number find this exhausting, and they are not wrong to.
Who should choose it
Anyone tracking for a medical reason, on a restricted diet, or curious about what their eating actually contains. Anyone counting calories to lose weight will be happier somewhere faster.
