I’ve used a lot of different food trackers over the years, and this one blows them out of the water in terms of breadth of micronutrient and body index tracking. It is also significantly more accurate than MyFitnessPal, allowing you to scan the bar codes to track food as a free feature. When I am financially stable enough to buy the premium I will to support this fantastic app and company, keep up the amazing work!

Thank you for the incredible review! We’re glad Cronometer’s detailed micronutrient tracking, accuracy, and free barcode scanner have made such a difference for you. Your support means a lot!
Great app, let me pay for ad free but not premium
EIijahcxz
The free app has everything I need but I would like to pay for no ads, the premium app offers all these features I don’t want so I won’t pay for it, I however would happily pay for an ad free version of the free appOverall a really good app that makes tracking super easy, highly recommended Also the ads are not intrusive, I just want to not have any!
Helpful app but too many ads
Wu. Y
The functionality and design of the app is nice, there’s a lot of options for you to input your meals and food. Lots of variety in what it tracks too, like vitamins and fibre etc. The only thing is there are way too many ads now, it’s almost unusable to use beyond a few minutes. Every 10-15 clicks results in a video ad that takes up the whole screen. The ad is only a few seconds but when it pops up 5+ times in less than 5 minutes it just feels excessive.
Developer Response
Hi there, we are so happy to hear you love the functionality and design of Cronometer we work hard to make it as user-friendly as possible with lots of information, so we are stoked to hear you like it! Thanks for the feedback about the ads. To be wholly transparent, we battled a number of issues that were causing an increase in ads; it took us longer than we would've liked to get to the bottom of it. That said, it should be better now, if it's still intense can you please message support@cronometer.com and we can investigate? Thanks!
Cronometer 🔛🔝

Recently switched over from MFP, and I gotta say that I find Cronometer elite in comparison. The UI Design is super clean & user-friendly. The comprehensive list of macro AND micro nutrients that you’re able to track is also on point, whereas before I didn’t have the option to track all the vitamins that I wanted. Overall, a solid app for those who wanna keep on top of their fitness.
We’ve improved Diary loading and fixed a nutrition display issue on the home screen widget. This update also includes other bug fixes.
