Cronometer
Detailed food and biometric tracking with unusually deep nutrient data.
Cronometer is a food, exercise, and health-tracking app focused on detailed nutrient breakdowns rather than just calories. Users can log meals by search, barcode, photo, or voice, set nutrition targets, sync supported devices, and review charts for macros, micronutrients, weight, and biometrics.
Why it stands out
- Tracks a much wider set of micronutrients than many calorie counters.
- Emphasizes verified and lab-analyzed nutrition entries rather than relying only on user-submitted foods.
- Combines diet logs with exercise, symptoms, glucose, weight, and other biometrics in one place.
- Barcode scanning is included in the free version, which is not universal among competing trackers.
- Offers separate workflows for individuals, nutrition professionals, healthcare, research, and education use.
Good to know
- Advanced insights, trends, and Gold-level features require a paid subscription.
- The value depends on consistent meal and biometric logging; incomplete records can make reports misleading.
- Device syncing is limited to Cronometer’s supported partner apps and hardware.
- Professional client-management features are part of Cronometer Pro rather than the standard individual app.
