How to Use Cronometer
Getting started with Cronometer is straightforward. Here's how to set up your account, log your first meal using the AI photo feature, and customize your nutrition targets for optimal results.
Create your account and set goals
Sign up for free on the web or mobile app. Use the setup wizard to input your age, weight, height, and activity level. The wizard will generate personalized calorie and macro targets based on your health goals, whether that's weight loss, muscle gain, or maintenance.
Log your first meal with AI photo capture
Tap the camera icon on the dashboard and snap a picture of your meal. Cronometer's AI will identify the food items and estimate portion sizes. Review the suggested entries and adjust serving sizes before saving to your daily log.
Customize your micronutrient targets
Navigate to Settings > Nutrition Targets and adjust your goals for specific vitamins and minerals. You can set targets based on RDA guidelines for your demographics or input custom values for particular health needs like iron optimization or electrolyte balance.
Sync your wearable devices
Go to Settings > Device Sync and connect your Fitbit, Oura, Apple Watch, or other compatible devices. This automatically integrates activity, sleep, and biometric data into your daily dashboard for a complete health picture.
Review your daily and weekly summaries
Check the Dashboard and Reports tabs to see how your nutrient intake compares to your targets. Use the visual charts and color-coded indicators to quickly identify deficiencies or excesses and adjust your diet accordingly.
