What is Cronometer?
Cronometer is a science-backed nutrition and calorie tracking app known for accuracy, used by millions of people who want more than just calories.
Where many trackers stop at macros, Cronometer logs up to roughly 95 nutrients and compounds, including vitamins, minerals, omega-3s and choline, drawing on lab-analyzed, verified nutrition data.
Its AI Photo Logging feature lets you snap a picture of a meal and have the app identify the ingredients, then prompts you to review and adjust serving sizes for accuracy, blending the speed of AI with human verification against trusted databases.
Additional logging options include barcode scanning and voice entry via Siri, and the app syncs with devices and services such as Apple Health, Fitbit, Garmin and Oura, while also tracking biometrics like weight and blood glucose.
It serves health-conscious individuals as well as dietitians, trainers and researchers who need reliable micronutrient data. Pros include exceptional nutrient depth, verified data quality, multiple fast logging methods, and a capable free tier.
Cons are that the AI Photo Logging feature is reserved for paid Gold subscribers, and that the data-rich interface can feel detailed compared with simpler calorie counters. Cronometer is a self-help nutrition tool and is not a substitute for personalized medical or dietary advice.
