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.

Thanks for the thoughtful feedback and welcome to Cronometer! We’re glad you’re enjoying the barcode scanner in Canada. Just a heads up: you can use group headers to organize foods by meal and view calorie and nutrient breakdowns for each group, not just the full day. We know switching apps takes time, and we appreciate you giving Cronometer a try!

Very frustrated with the new ads system. I've been using this app for over a year and loved it. Suddenly I'm getting ads every time I open the app. The ads are loud, disruptive and so frustrating, makes me want to throw my phone. I am considering finding another app. I notice that several people are commenting about this and the responses claim it's a bug that they figured out, yet I'm still getting the ads... :(

Thanks for letting us know about the increase in ads. We recently fixed a bug that caused this; updating to version 4.39.3 should significantly reduce the number of ads you see. If the issue continues after updating, please reach out to [email protected] so we can look into it further. We really appreciate your patience and loyalty!

This is the best calorie counting app I’ve found so far. I downloaded five different apps to see which one suits me best, and this one clearly stands out. Accuracy is the most important factor for me, and this app lets me log the exact weight of what I eat. Other apps require choosing preset portions, which forces me to do extra math. I also haven’t experienced the excessive ads that some users have mentioned, therefore I assumed they fixed the issue. Highly recommended.

Thank you so much for the detailed review. Accuracy is exactly what we built Cronometer around, so it’s great to hear that logging exact weights and avoiding preset portion math makes a difference for you. We appreciate you testing multiple apps and choosing us. Thanks for the recommendation! 🧡
