4 min read

According to a 2025 review, Cronometer is considered one of the most accurate and comprehensive nutrition tracking applications on the market, tracking up to 84 different nutrients. Mastering this powerful tool can significantly enhance your health and dietary goals, moving beyond simple calorie counting to a deep nutritional analysis.

Quick Summary

This guide provides step-by-step instructions on setting up and navigating the Cronometer app, focusing on profile customization, accurate food logging techniques, and advanced features for comprehensive nutritional analysis. It outlines how to set appropriate macro and micro-nutrient targets and leverage reports to achieve health objectives effectively.

Key Points

  • Accurate Profile Setup: Start by accurately entering personal details and health goals to generate reliable energy and nutrient targets from the outset.

  • Prioritize Verified Data: When logging food, select entries from verified sources like NCCDB or USDA for the most comprehensive and trustworthy nutritional data.

  • Weigh Your Food: Use a kitchen scale for the most accurate logging, as visual estimation can often lead to over- or under-estimation of calories and nutrients.

  • Track Everything: Log all food and beverages, including small additions like condiments and cooking oils, to ensure your calorie and nutrient counts are complete.

  • Analyze Your Trends: Utilize the detailed reports and charts in the 'Trends' section to gain long-term insights into your dietary patterns and spot potential deficiencies.

Setting Up Your Profile and Goals

Properly setting up your profile is the foundational step for accurate tracking. Your personal details directly influence the app's calculation of your daily energy and nutrient targets.

Create an Account and Enter Personal Data

First, download the Cronometer app from the App Store or Google Play and create a free account. Enter your accurate gender, height, weight, and date of birth during the setup process. This data is essential for calculating your Basal Metabolic Rate (BMR).

Customize Your Targets

After the initial setup, you can fine-tune your targets based on your specific health goals.

  • Set a Weight Goal: Navigate to More > Targets + Profile > Weight Goal to set your target and your desired rate of loss or gain. Cronometer will automatically adjust your daily calorie goal to create the necessary deficit or surplus.
  • Adjust Activity Level: Go to More > Targets + Profile > Energy Expenditure to set your baseline activity level. If you use a wearable fitness tracker, set this to 'none' and sync your device to avoid double-counting calories burned.
  • Refine Macronutrient Targets: In More > Targets + Profile > Macro and Energy Targets, you can choose how your calories are distributed across protein, carbs, and fats. You can set targets based on ratios, fixed gram amounts, or use the specialized Keto calculator.

Mastering Food Logging for Accuracy

Accurate food logging is crucial for reliable data. Cronometer's database is curated for accuracy, unlike many apps that use unverified, user-submitted data.

Methods for Adding Food

  1. Search Bar: Use the search function to find foods. For the most detailed nutritional information, prioritize entries from the NCCDB (Nutrient Data Laboratory database) or USDA. These entries are lab-analyzed and provide a broader range of micronutrient data.
  2. Barcode Scanner: For packaged foods, use the built-in barcode scanner for a quick and convenient entry. The app automatically pulls verified nutritional information. If the item is not in the database, you can submit the label for review.
  3. Custom Foods and Recipes: For homemade dishes, navigate to the Foods tab and create your own recipes. This is ideal for meal-preppers who eat the same meals regularly. For dishes you frequently make, like a morning smoothie, you can save it as a Custom Meal for one-tap logging.
  4. Use a Kitchen Scale: For the highest level of accuracy, weigh your food using a kitchen scale. Even small variations in portion size can add up over the day. Always log the food based on the weight in grams.

Logging Tips

  • Track Everything: Don't forget small items like condiments, sauces, or that handful of nuts. Every bite counts toward your daily totals.
  • Overestimate Restaurant Meals: When dining out, it's safer to slightly overestimate portions or log each component of your meal separately to account for hidden fats or sauces.

Leveraging Advanced Features and Analysis

Once you have a week or two of consistent data, you can move beyond basic logging to analyze your nutritional trends.

Use Reports and Charts

Cronometer offers robust reporting tools to visualize your progress.

  • Daily Report: Tap the energy summary circles in your diary to see a detailed breakdown of macronutrients and energy expenditure for the day.
  • Nutrition Report: Head to the Trends section (or Discover on mobile) to find the Nutrition Report, which averages your nutrient intake over a specified period. This helps you spot potential deficiencies in vitamins and minerals.
  • Charts: Create custom charts to track biometrics like weight, energy, or specific nutrients over time, helping you identify correlations and patterns.

Explore Nutrient Information

For any nutrient, you can tap or hover over its name to learn more. This feature provides a description of the nutrient's function, its best food sources, and your intake targets. This educational aspect is a key differentiator for Cronometer.
