About Cronometer.com

Cronometer is the premium web application for tracking your nutrition and health data.

Calorie reduced diets require a lot of information to perform optimally. In order to restrict caloric intake, but remain healthy, users of the diet must track their vitamin, mineral, and protein intakes with great care.

We aim to provide a complete solution for the smart dieter. Many diet-tracking applications fall short in some vital areas. Either they are not detailed enough, or they suffer from critical usability flaws. We believe that a diet tracker must be effortless to operate for the activity for which it will be used most of the time; keeping track of the foods you eat.

Cronometer is free to try.

  • Hi
    I just signed up to Cronometer and I am trying to enter Vegan Safe Vitamin B12
    supplement facts
    Serving size 1 ml:
    B12 2500 mcg (80% from Methylcobalmin and 20% from Adenosylcobalimin) 41,666 % DV

    I went to Create Food then tried to find the B12 stated above. The only one is Colbolmin, so I entered 2500 ug in it says i have 104451%. I put 1g for serving size because 1ml is 1g...I think. Thank you for any help

    • Joanne

      The DRI is 2.4 mcg so 104,167% is correct (2500/2.4). As for the servings, don't worry about the serving size being the exact. Why? Most supplements don't have a caloric value, so it is irrelevant from that aspect. You want to know you took 2500 mcg, right?

      Hope that makes sense, and 1ml of water = 1 gram of water, other substances are different but it is small for most practical applications.

      Regards,

      Frank

  • Dear Devs,

    I am a newbie in personal nutrition, previously I've been using My Fitness Plan, but recently I've discovered Cronometer, and I'm planning to give it a go through.

    I know I should've scoured the forums, but my question is only, what are the main differences between the Gold & Normal app version.

    Anyways, the app looks fantastic. Can't wait to try it.

      • Hello again,

        Thank you so much for your response, I just got some time off to browse the website and finally logged in. And the Gold Account surely sounds like a great deal price wise, especially the Oracle, which is a very unique feature helpful for beginners like me. I'll look into it once I got the basics covered.

        Have a good day.

    • When the creator started cronometer many years ago, he was making it specifically for the CRON diet (Caloric Restriction with Optimal Nutrition).

  • I just started using Cronometer after trying out a lot of other apps, and I am thrilled that I found it as I find it way better than any other system. Just one thing - would it be possible to get Vitamin K broken down into Vitamin K1 and K2 (MK4 and MK7) please?

    • Joan

      Thanks for the compliments and glad you like Cronometer. The data in Cronometer is for vitamin K, which is K1, K2, and K3. The databases out there don’t distinguish between them because the agencies doing food testing don’t test for the 3 different forms. Its all lumped into a vitamin K amount. Luckily, it is fairly easy to get all you need.

  • Using iPhone 4s with IOS 9. In the past, the Cronometer "Rearange Entries" action worked. Now it appears to not be working.

  • I use Cronometer on my iPad and love it. I put my weight at 155 but it changes it to 152.1. What should I do to correct it? Also, can I enter a target weight.?

    • Carol

      I went and looked and it is showing correctly. Your most current diary has a 155# entry and that is what is displayed on your weight graph and on your profile page. If you are looking at the graph for your weight goal on the profile page, I do see a 152.3 at the end of the graph line, but that is a projected weight for Mar 7. Not sure that is what you are referring too.

      You can set a target weight on the profile page in the weight goal box. You will see a blue weight number on the right of the graph. Click that to edit your target weight goal.

      Hope that all helps. You can send this to support@cronometer.com as well if you want to keep your personal data off the feed.

      Best regards

  • My weight chart just went flat. I have used Chronometer for a over a year - maybe even 2 - and this has never happened before. It used to separate out the variations so you could see it in graph form. Now no matter the change the graph are dots in a row.
    Any fix (PS I bought the gold edition -6-8 months ago thinking this would give me more - but it hasn't offered me much)

    • Val

      Can you send this to us at support@cronometer.com with the email associated with the account and we can take a look from our end. Be sure you have the zoom to fit box checked on the top of the chart.
