Cronometer

Cronometer's distinguishing claim is data quality rather than feature count. Its nutrition data is lab-analysed rather than crowd-sourced, which addresses the well-known weakness of consumer food trackers where user-submitted entries make micronutrient figures unreliable. The practical consequence is that it tracks up to 95 different nutrients and compounds, so users can see which essential vitamins and minerals they get most and least of, rather than only calories and the three macronutrients.

The product is sold to three distinct groups. Cronometer for individuals is the consumer app, with a free version. Cronometer Pro serves practitioners, with configurations named for dietitians, nutritionists, personal trainers and health coaches. An enterprise tier addresses healthcare workers, researchers and educators, which is where the emphasis on verified data matters most, since research and clinical use cannot rest on approximate figures.

Logging offers four routes, and the range exists because logging friction is what causes people to abandon tracking. Meals can be photographed and identified through AI photo logging, entered by voice, built as recipes, or saved as meals for reuse. Beyond food, the app tracks exercise and biometrics, and syncs with wrist, finger and phone devices, covering measures from pain symptoms and gut health through to blood sugar. Any diet can be tracked rather than a fixed set of presets, and a nutritional target wizard sets goals. Reports and charts cover analysis over time. The vendor states it encrypts all data, follows industry best practices and enforces strict access controls. Pricing is not published on the pages checked, but a free version is available.
