Displays temperature from the sensor in your FIT file in Celsius or Fahrenheit.
Not all watches record temperature. Garmin Fenix, Instinct, and COROS Vertix typically do.
Wrist-worn sensors are affected by body heat - readings may be several degrees above ambient. External sensors (Garmin Tempe) avoid this.
The overlay displays the temperature value as-is. MetricsOverlay doesn't correct for body heat offset.
Available in minimal, bold, digital, and gauge styles.
