Cronometer is a nutrition tracking app founded in 2011 by Aaron Davidson, originally intended to track his own nutrition while on the CRON diet. Davidson, a software developer, sought a nutrition tracker with a high degree of accuracy and detail. The company is based in Revelstoke, British Columbia, Canada. Cronometer is designed for anyone interested in precisely tracking their diet, whether for weight loss, muscle gain, or general health. It is also used by doctors, dietitians, and trainers.
Cronometer allows users to track calories, macronutrients, and up to 84 micronutrients. Key features include a barcode scanner, integration with wearable devices like Fitbit and Apple Watch, custom goals, and the ability to create custom foods and recipes. A photo logging feature allows users to snap a photo of a meal, and the app will identify the ingredients and estimate portions. The app has three subscription options: Basic (free), Gold, and Pro. Cronometer Gold, for individuals seeking improved functionality, typically costs $8.99 monthly or $49.99 annually and includes features such as ad-free use, advanced nutrient reports, custom charts, and food suggestions. Cronometer Pro, at $39.99 per month, is designed for health professionals to track client data. The app is available on iOS and Android.
