Consumed calories and macro nutrients values

I agree. It would be a task more to do, but it could be helpful for the app to better fine tune diet hints. It could be useful as well to have the app connected with Apple health app in order to get, other than caloric intake, also the caloric expenditure. The app uses standard parameters. Apple healths gives the actual caloric expenditure. In my case, for instance, the app’s caloric expenditure  is way above the actual one, hence the caloric intake advice is overvalued

Exactly my meaning but plse not only Apple but also Samsung Galaxy can be used to get for calories spent. Nevertheless in my opinion at least samsung exaggerates values a little bit. But back to the calories intake,  in my country there is an app Kaloricke tabulky, which tracks your intake really well. You can enter meals or scan barcode and that's it. At the end of the day I can see stats. Calories and grams of macronutriets which I could easily retype to the Dr.Muscle app each and every day.

There are lots of caloric trackers around. Currently I’m using Yazio, but the most used in the world is my fitness pal. That’s why the best option would be to import data from the health app (Apple or android) that collect all data related to caloric expenditure and intake, no matter what nutrition tracker you are using
