Ratings and reviews

It's pretty good. I especially like the barcode scanner because it works in Canada. I really wish it displayed calories and nutrient breakdown by meal not just the entire day, but it's not a deal breaker. (Edit: thank you for such a quick response and advice. It's now displaying calories by meal. Excellent product and support!) I've been using a different app for 15 years and only recently moved on to Cronometer so it takes time to adjust.

the potential complexity of tracking is why I both love and give a 4. I need the extended tracking for nutrients and that is amazing! but the learning curve is a little steeper than I'd like. I guess i should watch more videos and practice! I think this is going to be an exceptional tool in my health journey and more matched to how I like to see things.

Pro account. Great library and barcode readings are FAST. My one complaint is the inability to weigh everything, for example, Salsa. Options were only for ml, but I use a scale for measurement. Unless I am using exactly 1/4 cup then it's hard to measure with accuracy, and I want to log what I actually use. Developers: please fix that.
