 * The heart rate monitor is turned on only when Heart rate is selected and will take a few seconds to settle
 * The heart value is displayed in RED if the confidence value is less than 50%
 * NOTE: The heart rate monitor of Bangle JS 2 is not very accurate when moving about.

 * Uses the [BloggerSansLight](https://www.1001fonts.com/rounded-fonts.html?page=3) font, which if free for commercial use

 ## Future Development
 * Use mini icons in the information line rather that text
