What it does well

Worth knowing

What it is like to use

Cronometer rewards precision. Search results lean toward curated entries, the diary shows targets for a long list of vitamins, minerals and other compounds, and charts show how each day stacks up. People following a specific diet, working with a clinician, or just curious about their micronutrients tend to love it.

That precision makes logging slower. Choosing the exact record and weighing portions takes longer than accepting a photo estimate, and the app is built for people who are happy to do that.

The nutrient report

Cronometer’s defining screen is its nutrient summary. Each day is broken down into energy, macros and a long table of vitamins, minerals, amino acids and other compounds, each shown against a target. You can see at a glance whether you met your target for vitamin B12, magnesium or potassium, and charts over time help show which nutrients you are regularly short of. For a vegan checking B12 and iron, someone following a low-sodium plan or anyone working with a clinician, that is exactly the information they need.

Food data

The company describes its nutrition data as lab-analysed and verified, and search results favour curated entries over user submissions. That reduces the duplicate-entry problem that crowd-sourced databases have, at the cost of sometimes needing to search a little longer for a specific branded product.

Targets

Cronometer lets you set targets for energy and macros and customise targets for individual nutrients. People who know what they are aiming for can tune the app closely; beginners may find the number of options more than they need.

AI features

Cronometer now offers Photo Log, Voice Log and Crono Coach, an assistant that turns your own data into short guidance. All three are part of Gold. On the free plan you log by search and barcode.

Should you choose it?

Who it suits

  • People who want detailed micronutrient reports.
  • People following diets that need specific nutrients watched.
  • People working with a dietitian or doctor who want precise records.

Who should look elsewhere

People whose main goal is calories and who want logging to take as little time as possible.

Choose Cronometer if your question is “am I getting enough iron?” rather than “how many calories did I eat?”. If you want strong nutrient tracking and fast logging together, PlateLens covers both. Compare them: PlateLens vs Cronometer · Cronometer vs MacroFactor.

Verdict

Cronometer is the right tool when a nutrient report is the goal. For everyday calorie tracking, PlateLens is faster, tracks 82+ nutrients of its own, includes AI photo scans on its free plan and costs $25 a year less to upgrade.

Questions readers ask

Is Cronometer free?

Yes. Cronometer has a free plan with ads that includes the nutrient diary and barcode scanning. Gold costs $59.99 a year or $10.99 a month (checked September 20, 2026) and adds Photo Log, Voice Log, Crono Coach and ad-free use.

Is Cronometer good for weight loss?

It can be, especially for people who like precision. Its strength is detailed nutrient reporting rather than speed, so people who want quick logging often prefer a photo-first tracker.

How many nutrients does Cronometer track?

Cronometer says it reports up to 95 nutrients and compounds, one of the longest lists among consumer trackers.
