Cronometer Review: Lab-Grade Nutrient Data, Interrupted by Full-Screen Ads

Free vs Gold: 95 Nutrients for $0, Seven-Day Reports and Ads

The Basic plan is not a trial and has no end date. It tracks up to 95 nutrients and compounds, includes the full food database and unlimited barcode scans, syncs devices and exports all raw data. The limits are elsewhere: reports and charts cover only a seven-day window, and the AI tools, Photo Log, Voice Log and Crono Coach, belong to Gold, as do the Fasting Timer, Macro Scheduler, Recipe Importer and up to eight Nutrition Scores. Gold lists at $10.99 a month or $59.99 a year in the US; check the current price in the app, as it varies by region. Gold is also what turns the ads off.

NCCDB, USDA SR28 and Nutritionix: Where the Food Data Comes From

The help center names more than ten data sources. Most entries come from the NCCDB, curated by the University of Minnesota, which profiles over 17,000 foods for 70 nutrients; USDA SR28 adds more than 8,000. Packaged products arrive through barcode scans powered by Nutritionix, with over 400,000 labels, and through the CRDB, where staff review each user submission; a scanned product needs photos of its Nutrition Facts table and front. Photo Log matches a meal picture to those same entries rather than inventing values. Coverage thins outside North America: the Irish, Dutch, UK and Australian sets hold roughly 600 to 1,000 foods each, and Brazilian Play reviewers say local foods are missing.

Health Data and Ads: What the Apple Label and Play Card Disclose

Apple's privacy label lists contact info, identifiers and usage data as used to track you across other companies' apps, and links health and fitness data to your identity. Google Play's Data safety card says user IDs may be shared with third parties and that optional approximate and precise location can be collected for advertising. The privacy policy, revised June 23, 2025, states that free users' limited information goes to ad networks for targeted ads, that personal health information does not, and that personal data is not sold. Food photos and corrections may be used to train its AI models, and accounts inactive for 36 months may be deleted.

Health Connect, Apple Watch and Garmin: Sync Limits and No Offline Mode

On Android, Health Connect feeds in 13 biometrics, including blood glucose, HRV and sleep, plus workouts; nutrition comes back in only as water, while food and water go out to other apps. On iPhone, Apple Health imports activity and, with a toggle, sleep, with a backfill tool for missed days. Direct links cover Garmin, with up to two years of backfill, plus Fitbit, WHOOP, Oura, Dexcom, Polar, Withings, Suunto and Keto-Mojo. The Apple Watch and Wear OS apps show the day's energy and highlighted targets, only the Apple version adds recent foods, and free users see a single Nutrition Score. Nothing works offline: a staff reply on the official forum cited database licenses that bar storing the data on phones.
