Cronometer

Cronometer is what serious nutrition trackers use when they outgrow MyFitnessPal. While MFP optimizes for convenience and a massive food database, Cronometer optimizes for accuracy and depth — it tracks 84 micronutrients per day, making it the best tool for anyone who needs to know not just "how many calories" but exactly what's in those calories.

## Micronutrient Depth

Cronometer tracks nutrients that most apps ignore: - All fat-soluble vitamins (A, D, E, K — with K1 and K2 distinguished) - Complete B-vitamin panel (B1, B2, B3, B5, B6, B9, B12) - All major and trace minerals (including selenium, molybdenum, manganese) - Complete amino acid profile - Omega-3/6/9 fatty acid breakdown - Fiber types (soluble vs insoluble)

This depth matters for people managing conditions like kidney disease, thyroid disorders, autoimmune conditions, or following specific protocols like carnivore, keto, or therapeutic fasting.

## Data Quality

Cronometer prioritizes high-quality nutritional data from verified sources (USDA, branded manufacturer data) over user-contributed entries. Foods are marked by data source so you know how reliable the nutritional information is — a meaningful differentiator from platforms where user-submitted data can be wildly inaccurate.

## Biometric Tracking

Beyond food, Cronometer logs biometrics: - Weight, body fat percentage - Blood glucose, ketones, blood pressure - Sleep duration and heart rate - Custom biometrics you define

Overlaying biometric data with nutrition data helps identify patterns (e.g., glucose response to carb intake).

## Pricing

Free tier: full micronutrient tracking, basic biometrics, food diary. Gold ($8.99/month or $44.99/year): food trends, advanced biometric charts, Oracle AI, fasting timer, no ads.
