About FieldMetrics

FieldMetrics revolutionizes sports analytics by transforming raw data from your Garmin smartwatch into actionable insights for Team Sports. We empower athletes and coaches to make informed, data-driven decisions to enhance performance and strategy by providing detailed analysis of movement, speed, heart rate, and on-field positioning.

Unlock Your Potential With:

  • Positional Analysis using Garmin's GPS and heartrate data.
  • Control the different stages of your match and compare your performance in each half or quarter.
  • Custom field and court mapping, you can add your own field and use FieldMetrics in any venue, no expensive tracking equipment required, just your watch.
  • Detailed post-activity insights, performance comparisons, and seasonal progress tracking to monitor development, along with much more.

Maximize Your Data: For the most accurate and comprehensive analytics, we recommend using a dedicated chest strap heart rate monitor and ensuring your Garmin smartwatch model supports Multiband GPS technology for optimal location tracking.

Frequently Asked Questions

Authorizing your Garmin device is simple and secure. Navigate to the Settings page within FieldMetrics and click on the "Authorize Garmin" button. You will be redirected to the official Garmin Connect login page. After logging in with your Garmin credentials, you'll be asked to grant FieldMetrics permission to access specific data, primarily your activity files (like GPS tracks, heart rate, and timestamps) and basic profile information necessary for associating data with your account. This is a standard OAuth process, ensuring your credentials are not shared directly with us. You retain full control and can revoke this consent at any time through your Garmin Connect account settings under "Account Information" or "Connected Apps."

If your past activities aren't immediately visible after authorization, please use the "Fetch Historical Data" option found in your FieldMetrics Settings. Garmin's API policies may impose certain rate limits or restrictions on the bulk retrieval of very old historical data, so it might take some time, especially if you have a large activity history. We recommend checking your Garmin Connect account first to ensure the activities are present and synced there. While we strive to fetch as much history as permitted, the primary focus is on seamless synchronization of all *new* activities recorded after you've authorized FieldMetrics. These new activities should appear in FieldMetrics shortly after they are synced to Garmin Connect. If you encounter persistent issues with specific activities or the historical fetch, please reach out to us at info@fieldmetrics.io with details.

For the most precise heart rate (HR) and derived energy expenditure data, we strongly recommend using a dedicated chest strap heart rate monitor (HRM) paired with your Garmin watch. While optical wrist-based sensors in smartwatches are convenient and have improved significantly, chest straps (like the Garmin HRM-Pro or similar models) directly measure the electrical signals of your heart (ECG). This method typically offers faster response times to changes in intensity and greater accuracy, especially during:
  • High-intensity interval training (HIIT) or sports with rapid fluctuations in effort.
  • Activities involving vigorous or irregular arm movements (e.g., soccer, basketball, tennis, padel) which can sometimes cause optical sensor "noise".
  • Cold weather conditions, where reduced blood flow to the wrist can affect optical sensor performance.
Improved HR accuracy from a chest strap directly translates to more reliable energy expenditure (calorie) calculations and more insightful physiological metrics provided by FieldMetrics. When using a chest strap, ensure the electrodes are adequately moistened and the strap is fitted snugly but comfortably around your chest for optimal skin contact and signal quality.

FieldMetrics is designed to be compatible with virtually any Garmin device that records GPS data and standard activity metrics. This includes popular series such as:
  • Forerunner (e.g., 255, 955, 965)
  • Fenix (e.g., 6, 7)
  • Epix (e.g., Pro, Gen2)
  • Instinct
  • Venu
  • Vivoactive
And many others. For the best possible location accuracy, especially in challenging environments like urban areas with tall buildings or dense tree cover, we recommend using Garmin devices that feature Multiband GPS (sometimes referred to as Multi-GNSS). Multiband technology allows the watch to access multiple satellite systems (like GPS, GLONASS, Galileo, BeiDou) across different frequency bands, significantly reducing errors caused by atmospheric interference and reflected signals. Always ensure your Garmin device's firmware is up to date for optimal performance and compatibility.

To maximize GPS tracking accuracy with your Garmin device for FieldMetrics analysis, consider these tips:
  • Ensure Latest Firmware: Regularly update your Garmin watch's firmware via Garmin Express or Garmin Connect Mobile. Updates often include improvements to GPS algorithms.
  • Enable Multiband GPS: If your device supports it, enable Multiband GPS (or All Systems + Multiband) in your activity settings. This usually provides the highest accuracy.
  • Wait for GPS Lock: Before starting your activity recording, allow your watch sufficient time to acquire a strong GPS signal. Look for a green signal indicator or a "GPS Ready" message. Starting too soon can lead to less accurate initial tracking.
  • Data Recording Setting: For most Garmin devices, you can choose between "Smart Recording" and "1 Second Recording" in the activity settings. For detailed analysis like that in FieldMetrics, "1 Second Recording" is highly recommended as it captures more data points, providing a more granular track. "Smart Recording" saves space but might miss nuances in movement.
  • Be Aware of Environment: Understand that tall buildings (urban canyons), dense tree cover, deep valleys, and even severe weather can temporarily affect GPS signal quality. While Multiband helps, some interference is unavoidable.

Adding your specific courts or fields is crucial for contextualizing your performance data in FieldMetrics. You can do this by navigating to Settings → My Fields. Here, you'll be able to define new playing areas by accurately marking their four corners on an interactive map. We recommend using the satellite view on the map for greater precision when placing these corner markers. Defining your fields enables powerful features such as:
  • Generating heatmaps that are specific to the actual playing surface.
  • Analyzing your activity within different zones of the field.
  • Calculating accurate on-field distances versus total distance covered.
The more accurately you define your fields, the more insightful your FieldMetrics analysis will be.

The accuracy of data in FieldMetrics is directly dependent on the quality of data recorded by your Garmin watch. For GPS positional data, modern Garmin watches, especially those with Multiband GPS, can achieve accuracy within a few meters under ideal, open-sky conditions. Data is typically recorded every 1 to 1.3 seconds if "1 Second Recording" is enabled (which we recommend). Accuracy is generally better on larger, open fields compared to areas with signal obstructions. For heart rate and energy data, as discussed in another FAQ, optical wrist sensors are convenient but for peak accuracy, especially during intense or erratic movements, a chest strap HRM is superior. FieldMetrics processes the raw data (FIT files) provided by Garmin. We apply our analytics on top of this data, so the foundational accuracy relies on your device's capabilities, settings (like 1-second recording vs. Smart recording), and the environment in which you're active.

You have full control over the applications connected to your Garmin account. To revoke FieldMetrics' access to your Garmin data, you need to log in to your Garmin Connect account (either via the website or mobile app). Navigate to your account settings or profile, and look for a section typically named "Connected Apps," "Account Information," or "Third-Party Apps." Within this section, you should see a list of all applications you've authorized, including FieldMetrics. You can then select FieldMetrics and choose the option to remove or revoke its permissions. Doing so will prevent FieldMetrics from accessing any new activity data from your Garmin account. Data that has already been synced to FieldMetrics will remain in your FieldMetrics account unless you request its deletion in accordance with our privacy policy.
