Intermittent fasting is a popular weight loss and health program that involves eating only within a specific window of time every day. It has been proven to help people lose weight and improve their health.

For instance, if you eat only during an 8-hour period, you will be able to burn up to 150 calories per day. But, if you take a break and eat something, you will regain the calories you have burned and you will be able to gain weight.

So, in order to keep you in a state of fasting, the app will notify you when it is time to eat, when you should drink, and when you should stay fasted.

Moreover, the app will remind you to drink water and it will also help you calculate your water needs.
