Noom
If we talk about the accuracy of the received data, the winner can be considered to be not too functional, but a very objective application.
Noom does not show users the level of the obtained trace elements. You will not know how much calcium, iron, or vitamin C you ate today.
The number of carbohydrates, proteins, and fats in the food will also remain a mystery. But the calorie counts in it are quite accurate.
The app Noom differs from others in its focus on health, not on exhausting diets.
The app provides users with “coaches” who motivate them to achieve their nutritional goals.

Calorie counter
This is a simple counter with a cute hamster that will help you keep track of calories. Something like an old Tamagotchi toy.
Depending on the amount eaten it will lose weight or get fat. Besides, the hamster is a great motivation: it tells you when to eat, and when it is enough.
By the way, he can change his appearance: for example, instead of a hamster, he can plant a squirrel.
It is convenient that the food is not divided into breakfast/lunch/dinner. You can eat at least ten times a day. It is enough just to bring eaten products.
Also, the list of products is not too extensive – there are only common options for eating.
There are several diet programs in the application, which you can use. You can also set the number of calories and time of meal (with notification).
