Super useful. I use the free version and I can recommend. Adding foods or meals is easy and quick. Copying the previous day meal is a plus. Additionally, I love that I can download all my inputs as a csv (via bowser but still)! This gives me a lot of flexibility to anything I want with my data. I recommend Cronometer for all who want to track their calories intake.

I really like this app :) i love how easily I can see not only the standard macros but also fiber and vitamin and minerals intake. The option to add new foods and recipes is quick and smooth. The app does all of this even without subscription, just with some ads.
