Has definitely gotten worse over the years but is still probably the best app of this type, with the most detailed tracking. Full screen ads with a tiny untappable 'x' in the corner, random crashes and slowdowns, the usual software enshittification. I can now recommend this app to my friends and colleagues only reluctantly. It didn't used to be like this.

This is the best app I've found for including all the vitamins and minerals in the nutritional data and for showing the sources for food items (such as USDA). However, the ads are so frustrating because they pop up right in the middle of the screen and stay there when you scroll down. Also, it would be nice to be able to edit the sodium content for what you personally used, and to have the calories info that's at the top in a separate section instead so it doesn't take up so much screen space.

Hey Bryna! You can manually set your sodium intake for whatever you choose it to be! And there is also an option to hide the Diary Header if you want to focus more on your your Diary. Shoot us a message to support@cronometer.com and we will help you out. We are limited to a character count here! Thanks so much!

I tried to count calories, biometric data on my own. I tried other apps, but this one was by far the best. It boasts a HUGE database - even for lesser-known supplement products I couldn't find in other databases. You can make recipes (the recipe inherits the nutritional properties of what you add). And, to blow your mind, you can make recipes with *recipes* as ingredients and the "super recipe" will inherit the nutritional properties of all the ingredients. This app also allows tracking fasting if you pay. I'm a snob when it comes to data (thoroughness, accuracy, control, etc...) and I think this app could very well be the best of its kind.

Hey Michael! Thank you so much for the review - we are true data nerds too so we appreciate when others love us for the same reason! It sounds like you're enjoying a plethora of the features we include (great that you're using fasting and the custom recipe builder). If you haven't already found the "Explode Recipe" option be sure to check that out
