The modern health and wellness landscape is defined by data, and having your nutrition, exercise, and biometric data in a single location is key to making informed decisions. Cronometer facilitates this by integrating with a wide array of popular health platforms and specific-purpose devices. By connecting these tools, you can automate the process of logging everything from daily activity to blood glucose, freeing you up to focus on your health goals rather than manual data entry.
Major Health Platforms and Mobile App Integrations
For most users, the primary integration points will be with the default health applications on their mobile devices. These connections allow Cronometer to import and export crucial information that forms the backbone of a comprehensive health profile.
- Apple Health and Apple Watch: For iPhone and Apple Watch users, this integration is essential. Cronometer can import daily activity, exercise data, and biometrics like heart rate and sleep. With permission, it can also export data to Apple Health. A key tip is to set your activity level in Cronometer to 'Sedentary' if using an Apple Watch to avoid double-counting energy expenditure.
- Health Connect (Android): As of 2025, Google is shifting away from direct Google Fit integrations, with Health Connect becoming the central hub for data sharing on Android. Cronometer is fully integrated with Health Connect, allowing it to share a wide range of biometric, nutrition, and exercise data with other connected apps.
- Google Fit (Android): While direct integration is being phased out for new users, existing users can still sync with Google Fit by routing the data through Health Connect. This allows for the import of metrics like blood glucose, heart rate, and weight.
- Samsung Health (Android): Android users with Samsung devices can connect Cronometer with Samsung Health to sync various health metrics. Similar to other mobile integrations, this connection is only available via the mobile app.
Wearable Fitness and Sleep Tracker Integrations
For those who prefer a dedicated fitness tracker, Cronometer integrates with several leading brands to pull in detailed activity, sleep, and recovery data automatically. This is ideal for serious athletes and general health enthusiasts alike.
- Fitbit: One of Cronometer's longest-standing integrations, the Fitbit connection automatically pulls daily activity, logged workouts, heart rate, sleep stages, weight, and more advanced metrics like HRV, SpO2, and skin temperature from compatible devices.
- Garmin: Garmin device users can sync exercise, workouts, daily activity, and time-series heart rate data directly into their Cronometer diary.
- WHOOP: The WHOOP integration syncs key biometric data, including sleep, recovery, and activity metrics, for deeper performance insights.
- Oura: This integration allows for the import of time-series heart rate and sleep data, providing a holistic view of your daily activity and recovery.
- Polar: Polar device data, including activity and exercise, can be synced with Cronometer.
- Withings: For Withings users, biometric data from scales and other devices can be imported.
- Suunto: Active users of Suunto watches can sync their activity data directly with Cronometer.
Health Device and Clinic Integrations
For individuals with specific health monitoring needs, Cronometer offers integrations with specialized medical and biometric devices. It also supports some professional clinic platforms via API access.
- Dexcom: Users of Dexcom's Continuous Glucose Monitoring (CGM) systems can integrate their data for seamless glucose tracking.
- Keto Mojo: This connection allows users to import blood ketone and glucose readings, which is particularly useful for those on a ketogenic diet.
- Biosense: Users of the Biosense breath ketone analyzer can import their data to track ketosis.
- Qardio: Data from Qardio's blood pressure monitors can be synced to monitor cardiovascular health.
- Professional Platforms (Everfit, Kalix, Practice Better): For health coaches and professionals, Cronometer's API allows certain nutrition data to be accessed via these platforms.

- Access Connections: Go to 'Connect Apps & Devices'.
- Select Your Device: Choose your desired device or app from the list (e.g., Fitbit, Garmin, Apple Health).
- Authorize Access: You will be prompted to log in to your account for that specific device (e.g., your Fitbit account). This is to grant Cronometer permission to access your data.
- Choose Data to Sync: In some cases, you can select which specific metrics you want to import. This is a good way to avoid double-counting data.
- Complete the Process: Once connected, the data will begin to sync automatically, with an option to 'Force Sync' for manual updates.
Conclusion
Cronometer's wide range of integrations is a major strength, allowing users to consolidate their health data from multiple sources into a single, detailed diary. Whether you use a standard health platform like Apple Health or a specialized device like a Dexcom CGM, Cronometer's syncing capabilities automate much of the tracking process. This streamlined approach provides a more complete picture of your health, combining nutritional intake with physical activity and biometric data, ultimately empowering you to achieve your wellness goals more efficiently.
