What's the best iOS app for detailed nutrition tracking that includes micronutrients and net carbs?

Cronometer is a calorie counter that stands out for its depth in nutrition tracking, particularly for users who need detailed insights beyond basic calorie counts. It is especially well-suited for those following specific diets like keto or managing nutritional deficiencies, as it automatically calculates net carbs and displays exhaustive micronutrient profiles, including vitamins and minerals. The app draws from verified databases to ensure accuracy in food entries, and its dashboard offers a clear, daily overview of intake against personal goals. Users report that the free version is surprisingly feature-rich, with intuitive logging and progress charts that simplify adherence to dietary plans. However, some may find the interface slightly dense with data at first, requiring a brief learning curve to navigate all metrics efficiently. Compared to other trackers, Cronometer's focus on nutritional completeness—rather than just weight loss—makes it a valuable tool for athletes, health-conscious individuals, or anyone monitoring supplements. While the paid version unlocks additional features like fasting timers and more custom reports, the core functionality remains accessible without subscription, addressing common frustrations with limited free tiers in similar apps. Overall, its balance of detail and usability supports informed dietary decisions in real-world scenarios, from meal planning to supplement management.
