Absolutely fantastic app that has changed my life when I started using it. 8kg down over 4 months. I extensively reviewed many apps available on the market such as myfitnesspal, macrofactor, etc and they all pale in comparison in terms of their feature set and pricing. The community is strong on reddit and it’s clear the product team is listening. No ads, pointless paywalls, vendor lock in. The UI UX is intuitive and makes logging daily effortless. I upgraded to Pro after two months of consistent logging and appreciate the repeat foods option. I also found I had a calcium deficiency thanks to the micronutrient breakdown. I recommend cronometer to anyone who is taking their nutrition seriously.

Game Changer
Jamie Tanner
This app was a game changer for my fitness & nutrition. It’s very intuitive, has an extensive database of food & makes it very simple to make your own recipes, log new foods or make changes. It has all the features you need to make it simple & quick to copy and paste days or meals, track your fasts or log your biometrics. And above all, they are privacy focussed, this is important to me as I want to be the customer, not the product. Lastly the customisable charts give you valuable insights into what’s working and what’s not. Cannot recommend this app highly enough, to the team behind, thank you - I’ve lost 10kgs in six months, hit my target weight & changed my life for the better.
Use it everyday for last three years

When I started out on my Low Carb journey 3 years ago I tried a few different Apps. To help me understand my food consumption in Macro terms. I found that Cronometer worked best for me and I am still using the Gold version and it gives me great data. Now Cronometer are adding extras like Importing Recipes. I am very happy to be using Cronometer. Liam Mc Grath Ireland

Hi Liam!We are so happy to hear that Cronometer has helped you on your low carb journey! One of our staffers works out of Ireland so we have some roots planted there - it's neat to hear people are using us all over the globe! Thank you for sharing your story and our most sincere gratitude for further supporting us by subscribing to Gold! :)We wish you all the best in health!
Good idea but I think MFP still beats it

I like how in depth it goes even on the free version however after switching over from other competitors for a few days I’ve found that majority of the foods I try to scan are not in the database. For reference I live between Ireland and the UK and maybe it just isn’t utilised a lot in this region. It’s a pity because I do actually like this app and I think it has the potential to be a lot better than competitors however as it is a food logbook essentially the data base issue is a fairly significant problem.
Developer Response
Hey there!Thanks so much for the feedback about the app, we're constantly adding thousands of verified foods to our database every single week and many of those are from Europe! Hopefully in the future we have a more robust offering.
Bug fixes and polish to keep Cronometer running smoothly. Improved stability and a smoother everyday experience.
