3. DEVICE COMPATIBILITY:
- Requires an Android device with Bluetooth 4.0 (BLE) or higher support.

- The device must have location services enabled for Bluetooth scanning (Android system requirement).

Fit Metrics is the ultimate tool for athletes who want to stop guessing and start measuring. Connect your Bluetooth heart rate monitor and transform your device into a professional performance dashboard.

Why choose Fit Metrics?
Designed with high-intensity training in mind, our app lets you visualize your effort in real time EXCLUSIVELY through data received from your external sensor, helping you stay in the right zone to maximize your results.

KEY FEATURES:

• STANDARD BLUETOOTH CONNECTION: Compatible with most heart rate monitors on the market (Polar, Garmin, Wahoo, Magene, etc.) that use the BLE protocol.

• REAL-TIME METRICS: View your heart rate, effort percentage, and calories burned. The data comes directly from your external sensor.

• TRIMP CALCULATION: An algorithm that measures your actual training impulse to optimize your progress.

• HIGH-VISIBILITY DISPLAY: A high-contrast interface designed for easy viewing from a distance during your WOD.

HEALTH NOTICE AND DISCLAIMER: This app is a fitness and wellness monitor, not a medical device. The data displayed depends entirely on the accuracy of the connected external sensor. It should not be used for the diagnosis, cure, mitigation, treatment, or prevention of any disease.
