I love this app and love being able to track my nutrients and macros. The scanning is almost always spot on, I LOVE that I can enter recipes, and am glad to be able to keep up with my health overall in a really simple way.

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.

Best Food Tracking App

I’ve tried other food tracking apps and this is by far the best one. The easy-to-use interface is what really separates this app from the competitors. I was actually recommended this app by a friend after I told him that I dislike most food tracking apps and I’ve used it ever since!

Food is super easy to find and the barcode scanner works great. I love that everything is pulled from databases and not clunked up by manual entries.
