Great overall

Great app with a ton off pros:

Clean food database
Great data visuals
Integration with health devices
Barcode scanner
Net carbs
Blood glucose logging
Ketone logging

Though it has some negatives:

Incomplete food database
Zero widgets
Force touch menu missing
Health app heart rate doesn't average

Hope they can better Integrate the negatives I'm rooting. Then I'd subscribe.

I like it but....

There REALLY needs to be a multi add function for food because going in every day and entering almost the same foods one by one by one by one gets really tedious. I do love the fact that I can see how many vitamins and minerals I’ve had throughout the day though, that part is really great! Please think about adding a multi add function to your app so it makes it more user-friendly.

Fair start

Doesn’t track time of entry. UI is subpar and completely unprofessional. Fields are presented under the keyboard so you can’t see what you’re entering. Portions are really strange... like, 8oz portions here where the bottle says 2 x 9oz portions, plus the field is hidden under the keyboard.

The basics are here, though. Would be nice if they could get it right.
