❤️ Just your heart rate.. where the heart rate flashing closely approximates your actual heart rate.

Thanks to Kristof for the example code this is based on.

You can also change the colour scheme as desired., or show a flashing circle instead - you just need to change the text colour to suit.

PLEASE NOTE: The animated flashing heart DOES NOT impact your battery. Having tested over a number of days I still get good battery life. However, your own experience, and other watch usage etc, may be different.

Donations are very welcome,
