Cronometer

Cronometer tracks over 60 micronutrients including all amino acids, vitamins, minerals, fat breakdown, carbohydrate breakdown, sugar subtypes, and sugar alcohols. The mobile version of Cronometer has a simplified interface but retains full functionality compared to the web version. Cronometer can log biometrics including blood glucose, ketone readings, and ferritin levels. Cronometer user data is not examined or data-mined by default; users must opt in to share data with researchers. Cronometer is a diet-neutral nutrition tracking application that follows current research rather than promoting any specific regimen. Cronometer is available free with ads or ad-free for approximately $3, with both tiers offering full functionality. Cronometer's meal timestamp feature was recently added and is designed to support future intermittent fasting functionality.
