TL;DR: Pressing the enter button will flip between pages, holding it will open menus. For touch devices tapping the screen will advance pages and long pressing will open menus. Some devices seem to require a mix between touch controls and physical buttons. You can add your birth date in the user settings to improve the accuracy of the calorie estimation.
For more information about the available settings and calorie calculation logic please consult the readme: https://github.com/pyrob2142/FastingWidget/blob/master/README.md

Fasting Widget allows you to keep track of your fast right on your wrist.

Features:
- Set a goal by choosing from various popular fast lengths, add your own lengths or fast freely without any commitment
- Keep track of your fast's duration and how long you have left until you meet your goal.
- Get an estimate of your real-time calorie burn based on implementations of BMR and activity formulas (see section Real-time Calories Estimation for details)
- Keep yourself accountable by maintaining a streak
- The widget can be configured via Garmin Connect Mobile or Garmin Express
- No account or registration required. All data comes from either your user settings (date of birth, body fat percentage) or your user profile (weight, height) and is only used during runtime for the calorie calculations
