Ultimately, the user must provide the app with information about what they ate during the day and in what quantities. And yes: the occasional piece of chocolate is part of it too.

Based on this information, digital assistants determine how much carbohydrates, proteins and fats you consumed. And—depending on the app—suggest what you could change to eat healthier.

Help with choosing

If you’re considering using a nutrition app, it’s best to be clear about what exactly he or she needs beforehand.

According to c’t, some apps focus on tracking calories and therefore can help you lose weight. This is the case with the EasyFit kcal, Lifesum, MyFitnessPal and Yazio apps. The “Foodiary” application is focused on the nutrition of athletes.

It may also be practical if the app has a barcode scanner. This means, for example, that the nutritional information for strawberry yoghurt can be quickly recorded, saving you the hassle of entering it. myFoodDoctor, Lifesum, Yazio and MyFitnessPal offer this feature.

And if you need some cooking inspiration, choose a recipe database app. It can be found in the Foodiary, Lifesum, Yazio or MyFoodDoctor apps. Another benefit: If you’re cooking from a recipe, you can enter nutritional values ​​in just a few steps.

Costs: Subscriptions often cost between 10 and 15 euros per month.

The What I Eat test app is completely free. All we can expect from the app behind the Federal Nutrition Center is “the very first rough analysis,” Dorothy Wiegand said. Portions, for example, can be entered in approximately 0.5 increments, but not to the nearest gram.

Applications with more detailed information come at a price. You can try many of them for free. But if you want to use all the features long-term or don’t want to be distracted by ads, you’ll have to upgrade to a paid version, usually a subscription model. “The costs are between 10 and 15 euros per month,” summarizes Wiegand.

According to the expert, the nutrition app is not intended for continuous use. That’s why you should think carefully about signing up for an annual subscription.

“Ideally, after one, two or three months, I will have learned a lot about my eating habits,” Wiegand says. Once you’ve developed new, healthier habits, it’s time to delete the app again.
