Cronometer vs MacroFactor: detail or adaptive targets

Cronometer vs MacroFactor is a choice between two kinds of detail. Cronometer shows you what’s in your food: up to 95 nutrients, from a database it says is lab-analyzed or verified. MacroFactor shows you what your body does with it: it estimates your calorie burn from your log and weight trend, then adjusts your targets every week.

Pick Cronometer if you care about vitamins and minerals, or want to start free. Pick MacroFactor if your main question is “how much should I eat?” and you’ll log every meal in full.

Everything below about both apps’ features and prices comes from their own pages and app store listings, read on November 9, 2026. We didn’t test either app ourselves.

Key takeaways

• Cronometer’s strength is nutrient depth. Its free Basic plan includes up to 95 nutrients, the full database and a barcode scanner. Gold is $10.99 a month or $59.99 a year.
• MacroFactor’s strength is its target. It back-calculates your energy expenditure from intake and weight trend and updates your calories weekly. It has no free plan: $11.99 a month, $47.99 a half year or $71.99 a year, after a 7-day trial.
• Cronometer sets your calorie target from your profile, activity level and weight goal, and can add the exercise you log or sync. MacroFactor ignores watch calorie estimates on purpose.
• Both apps were in a 2024 study of 16 food-logging apps, and neither matched the reference menus across the board. No study we found has tested MacroFactor’s algorithm.
• MacroFactor’s method needs complete days. If you often log half a day, that matters more than any feature.

Which one should you pick?

That’s the short version. The rest gives the reasons, so you can check them against how you eat.

How do Cronometer and MacroFactor differ at a glance?

As of November 9, 2026, this is what each company says about its own app.

MacroFactor’s voice logging is its Describe feature, which its help article says lets you “speak or type out the contents of a meal”.

Sources: Cronometer’s home page, Gold page, free plan page, database page, Energy Target and Macro & Energy Targets help articles, and US App Store listing; MacroFactor’s app page and US App Store listing. Prices change, so check them before you subscribe.

How does each app set your calorie target?

This is the biggest difference between them, so it’s worth a minute.

Cronometer starts from a calculation. Per its Energy Target article, your target starts from your weight goal. It adds your BMR and a baseline activity level, then subtracts a deficit (or adds a surplus) for the rate you choose. You can also type in a fixed target of your own.

If you’ve set a weight goal, it adds exercise on top by default, per its Macro & Energy Targets article. If you log a workout or import activity from a device, any burn above your baseline is added to that day’s target. Its example: a 60-minute bike ride takes a 1,673-calorie target to 2,155. You can switch this off.

MacroFactor starts from your results. Its app page explains the math: calories in, minus the change in stored energy, equals calories out. If you’ve eaten about 3,000 calories a day and your weight trend suggests a 200-calorie surplus, your burn is about 2,800. It updates that estimate as you log, and adjusts your targets each week.

It doesn’t use your watch’s calorie estimate for this. Its FAQ says weight and nutrition data “give us all the information we need”.

The trade-off. A formula is a starting guess, and it can be off for you. MacroFactor’s estimate learns from your own data, but only if the data is complete. That leads to the one thing to know before you pay for MacroFactor.

Why partial logging decides it for MacroFactor

MacroFactor is open about its weak spot. Its app page calls partial tracking the method’s “Achilles heel”. If you log breakfast and lunch but not dinner, the app can’t tell. It sees a light day, so your estimated burn drops, and your future targets drop with it.

Our MacroFactor review covers its advice in detail. In short: estimate the missing meal, or delete the day entirely, because a blank day does less harm than half of one.

Cronometer’s target comes from your profile and weight goal, not your food log (per its help articles), so a missed dinner only affects that day’s numbers. That isn’t a reason to prefer it. It just means the cost of a gap is smaller.

If you know you leave gaps, that habit matters more than either app’s features. Gaps are common. In a 12-week weight-loss trial published in 2019 in JMIR mHealth and uHealth (PMID 30816851), one group used MyFitnessPal on its own. Those adults logged their diet on a median of 2.9 days a week.

Our post on food diary apps covers why logging fades, and what helps.

What does Cronometer do best?

Depth, and a generous free plan. As of November 9, 2026, Cronometer Basic includes:

• Up to 95 nutrients and compounds, with targets you can customize for macros and micronutrients.
• The whole database, which Cronometer says comes from lab-analyzed data and over 10 sources, including the Nutrition Coordinating Center database and USDA’s SR28. It says every submitted branded food goes through a verification process.
• A free barcode scanner, and syncing with apps and devices. Its App Store listing names Apple Health, Apple Watch, Fitbit, Garmin, Oura and Whoop.

The free plan’s limits: charts and reports cover a 7-day window, and there are ads. Gold adds photo and voice logging, a recipe importer, a macro scheduler for different targets on different days, a fasting timer, nutrient search, and an AI assistant called Crono Coach.

The trade-off is that it’s a lot of data. If you only want calories and protein, most of it is noise. For how Cronometer compares with the incumbent, see Cronometer vs MyFitnessPal.

What does MacroFactor do best?

The target, and fast logging with nothing locked behind a higher tier. As of November 9, 2026, every MacroFactor plan includes:

• Weekly target updates from your intake and weight trend, which MacroFactor calls “adherence-neutral”: they follow what you ate, not how closely you hit last week’s number.
• AI photo logging, typed or spoken descriptions, and barcode and label scanners, with a recipe importer.
• Micronutrient tracking, including the top contributors for any nutrient.
• No ads, and a promise that your data “will never be sold”.

What it doesn’t have: a free plan, a desktop version, or calorie burn from activity trackers. It connects to Apple Health and Google Fit, and can import the last 30 days of data from them. Our MacroFactor vs MyFitnessPal post compares its method with a formula-based app.

What does each one cost?

As of November 9, 2026, in the US:

On a yearly plan the two are $12 apart. The real price gap is the free plan: Cronometer Basic costs nothing, and MacroFactor has no free tier. Paying month to month costs about twice as much as a yearly plan in both apps. For each app’s refund and cancellation rules, see our MacroFactor review and Cronometer review.

Which one has the more accurate numbers?

Neither is exact, and the research is thin. Here’s what we found in PubMed on November 9, 2026.

One study included both apps. A 2024 paper in Nutrients (PMID 39125452) took apps from the top of Australia’s app stores.

Researchers entered three set 3-day menus, designed by dietitians, into 16 food-logging apps. Cronometer (version 4.19.5) and MacroFactor (version 2.6.8) were both among them. Each app’s output was compared with a reference analysis of the same menus.

Across the apps, energy came out too high for a Western menu, by an average of 1,040 kJ (about 250 calories).

It came out too low for an Asian menu (by 1,520 kJ, about 360 calories) and a menu based on Australia’s dietary guidelines (by 944 kJ, about 225 calories). The paper reported each app’s energy in a chart, so we don’t quote a figure for either app.

It did tabulate each app’s macro split. For the Western menu:

Cronometer matched the reference on fat and ran high on carbs. MacroFactor matched on carbs and ran high on fat. On the Asian and guideline menus, both apps put the carb share 5 to 12 points above the reference: Cronometer 51% and MacroFactor 55% against 46% on the Asian menu, and 58% and 60% against 48% on the guideline menu.

Neither app was consistently closer, and the reference data were Australian. Read this as a caution about logging apps in general, not a verdict on either one.

An older US study included Cronometer, but not MacroFactor. A 2023 paper in JMIR Formative Research (PMID 37327038) had one researcher enter the same 3-day food record into five US apps. Against a research database, Cronometer totaled 4,487 calories to the reference’s 4,770, about 6 percent low.

It was the only one of the five with no significant difference on calories or macros. One record entered by one person is a small test, so treat it as a clue.

MacroFactor’s algorithm hasn’t been studied. A PubMed search for “MacroFactor” on November 9, 2026 returned seven results, none of them about the app. So its method rests on energy-balance math and the company’s own explanation.

What this means for you. No study we found gives a calorie total for MacroFactor that we can quote, and Cronometer’s best result comes from one small test. So don’t pick between them on accuracy alone.

The 2024 Nutrients paper also notes a limit of manual logging in general: oils, butter, sauces and condiments added in cooking are easy to miss. Portions are hard to pin down, too. Our guide to how AI calorie counters work covers that blind spot.

Where does Getfiit fit?

We make Getfiit, so weigh this section with that in mind. It’s an AI nutrition and fitness coach that lives in WhatsApp, so there’s no new app to install.

You send a photo, a voice note or a sentence, and it replies with calories, protein, carbs and fat. It sets daily targets from your goal and profile, and checks in at a time you pick.

Here’s an illustration of a log, not a measured result:

lunch12:38

Looks like a salmon poke bowl with rice. Was there a sauce or dressing on it?12:39

yes, some spicy mayo12:40

Logged with a drizzle of spicy mayo. Your calories and macros for today are updated.12:41

It isn’t a substitute for either app’s specialty. If you want a full micronutrient breakdown, Cronometer is built for that. If you want an expenditure estimate from your weight trend, MacroFactor is built for that.

Getfiit is built for people who keep dropping the logging step. It estimates, says so, and asks when a photo leaves something open.

As of November 9, 2026, Getfiit costs $19.99 a month after a 3-day free trial, and you can cancel anytime. See how it works.

Tracking isn’t right for everyone

Both apps ask you to watch numbers closely, and that suits some people better than others. If counting brings on stress or restriction, or you have a history of disordered eating, talk to a doctor or a registered dietitian before you start any tracker.

Frequently asked questions

Is Cronometer better than MacroFactor?

It depends on what you want from a tracker. Cronometer is built for nutrient detail and has a free plan. MacroFactor is built around a calorie target that adapts to your weight trend, and it’s paid only. For calories and macros alone, either can do the job.

Is Cronometer free? Is MacroFactor free?

Cronometer has a free Basic plan with up to 95 nutrients, the full database and a barcode scanner, plus ads. MacroFactor has no free plan, only a 7-day trial. Both as of November 9, 2026.

Does MacroFactor track micronutrients?

Yes. Its app page lists “full micronutrient tracking” and the top contributors for any nutrient. Cronometer’s whole design centers on micronutrients, though, with up to 95 nutrients and compounds on its free plan.

Can Cronometer adjust my calories like MacroFactor?

Not in the same way, per its own help pages. Cronometer recalculates from your profile and weight goal, and can add the exercise you log or sync. MacroFactor estimates your burn from your food log and weight trend instead.

Do I need a food scale for either app?

No. A scale makes entries more precise, but a consistent estimate you keep logging is worth more than a perfect log you stop. Our guide to tracking macros without weighing everything shows how. The FAQ on our home page answers common questions about estimates.

Your next step

Decide what you actually want to see each day: nutrients, or a target that learns. Then give that app two ordinary weeks.

If you’re still logging complete days on day 14, you’ve found your tracker. If not, the chore is the problem, not you. Browse our other tracker comparisons.
