Lifesum is a tracking app. If you want to get an overview of how many calories you eat, you can easily save your meals in the app. Additionally, the app calculates how many carbohydrates, proteins and fats you eat. The app also allows you to track your vegetable and fruit consumption, which could help you balance your diet. In addition, you can save how much water you drank every day. All of these features are free. However, for additional services, such as recipes, you have to take out a subscription. As an additional feature, it is possible to enter your daily exercise, and the calories burned are automatically included in the calorie calculation. What's good about this app is that with the help of calorie tracking, you get an overview of how much you eat per day. Also, having an overview of what your current eating habits are like in your meal diary in retrospect can help you see what you might want to change or adjust. Especially good about the app is the possibility to track vegetables and fruits, as these are part of a healthy and balanced diet and are often neglected in other apps. The app calculates your turnover from your height and weight. However, this is only a rough value and should always be treated with caution. You should know your body reasonably well, and still otherwise deal with the issue. In addition, you should make sure to really track your daily exercise - because otherwise the calorie value of your app is not adapted to your lifestyle and not very helpful. And even then, you should always keep in mind: The app can provide you with a rough estimate - it may still be that your personal needs are different than the app tells you, so you should really treat the app's information with caution.
