KalTrack
Comparison
The micronutrient specialist against a fast photo estimator. These are aimed at genuinely different people.
4.8 from 96,950 ratings · Free
The precision instrument of the category. Cronometer's data comes from curated, lab-analysed sources rather than crowd submissions, and it tracks around eighty micronutrients rather than just calories and the big three macros. Popular with dietitians and with people managing a condition.

A camera-first tracker. Point at the plate for an AI estimate you confirm in two taps, or scan a barcode or nutrition label to get exact published figures instead. Built around the idea that a photo estimate is an estimate, with cuisine coverage beyond American food databases. New, and small.

you care about micronutrients, you weigh your food, or you have a clinical reason to need accurate intake. Cronometer's data quality is the best in the category and nothing that estimates from a photo can compete with a gram weight against a lab-analysed entry.
you want calories and macros with as little friction as possible and micronutrients are not why you are here. The two are not really substitutes for each other.
This is the least contested comparison on the site, because Cronometer and KalTrack are not competing for the same person.
Cronometer is what you use when the numbers have to be right: lab-sourced data, eighty-odd micronutrients, gram-level entry. If you are tracking iron for a diagnosed deficiency, or working with a dietitian, or you simply enjoy the rigour, it is the best tool in the category and a photo estimator is not a serious alternative. We would tell you to use Cronometer.
KalTrack is for the other job: getting a usable calorie and macro figure into a diary in ten seconds so the diary actually gets filled in. It estimates, and it says so everywhere. It tracks the big three macros, not the micronutrient panel.
The honest recommendation is that if you read Cronometer's feature list and felt relief, use Cronometer. If you read it and felt tired, that reaction is the whole reason KalTrack exists. Some people run both — Cronometer for a careful audit week, something faster for the other fifty-one.
Method: figures come from each app's public App Store listing on the day this page was built, and from each app's own published pricing. Features were checked against the apps' own descriptions. We make KalTrack, so treat this as our account of the difference, not a review.
