A macro tracker built by evidence-based fitness people, whose distinguishing feature is an adaptive algorithm that estimates your actual energy expenditure from your weight and intake data and adjusts your targets weekly. Fast logging interface, curated database, and a serious following among lifters.

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 lift, you weigh your food, and you want your calorie target to adapt to your measured expenditure rather than a formula. MacroFactor's expenditure model is the best implementation of that idea available and it needs accurate input to work.
you are not going to weigh your food, and you would rather have approximate numbers you actually record than precise ones you do not.
MacroFactor is excellent and its central idea — model your real expenditure from your own data, then adjust the target — is better than the TDEE formula most apps use, KalTrack included.
But that algorithm is only as good as what you feed it. It is designed around people who weigh food on a scale and log it accurately, and it is explicit about that. Putting photo estimates into an adaptive expenditure model would degrade the thing that makes it worth having.
So this comparison resolves cleanly on one question: will you weigh your food? If yes, use MacroFactor, and do not let a camera anywhere near your intake data. If no — and most people will not, for years, honestly — then the choice is between approximate numbers you record consistently and precise numbers you stop recording in week two.
KalTrack is built for the second case and does not pretend otherwise. It adapts a budget from weight trend and Apple Health activity, which is a cruder version of what MacroFactor does properly. If you are serious enough about training to be reading a comparison like this one, there is a good chance MacroFactor is the right answer for you.
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.
