Cronometer is a Canadian nutrition tracking app and calorie counter, started in 2005 by founder Aaron Davidson. It tracks macronutrients, micronutrients, exercise and biometrics, using verified, lab-analyzed food data from sources such as the Nutrition Coordinating Center and the USDA rather than crowdsourced entries. It ships web, iOS and Android apps with a free Basic tier and a paid Gold subscription, plus Cronometer Pro for dietitians, nutritionists, trainers and health coaches, and an Enterprise offering for healthcare, research and education. It does not publish a public developer API: no developer portal or API documentation was found on cronometer.com, and community forum threads say API access is only given to select partners.
