This free app is an essential tool for anyone who is trying to loose weight, because it allows you to calculate your personal basal metabolic rate for the day. This is the number of calories that your body needs to function properly.

It is calculated based on your age, gender, height, and current weight.

If you want to get to the desired weight, you need to eat less than the calculated amount of calories. This is the number of calories you need to consume every day in order to lose weight.

The app allows you to see the progress of your weight over time. You will also be shown your calorie intake over time, so that you can check if you are successful.
