MacroFactor review: cost, free trial and who it is for

No, and the publisher is upfront about it. In the FAQ on the official app page, Stronger By Science says there is not, and never will be, a free version of MacroFactor. You can download the app at no cost from the App Store and Google Play, but it starts with a 7-day free trial, followed by an auto-renewing subscription.

The publisher ties this to its business model: no ads, no ad networks tracking you, data that is never sold, and full access to every feature as soon as you subscribe. So there is no “Premium” tier to unlock: during the trial and afterwards, you use the same app.

MacroFactor offers three lengths: one month, six months or one year. Its Help Center lists $11.99 a month, $47.99 per half year and $71.99 a year, and notes that prices vary with each country’s exchange rate and taxes. In Europe, the App Store’s list of in-app purchases shows the amounts in euros and kroner:

Stronger By Science also publishes MacroFactor Workouts, a strength training app: routines built around your goal, level and equipment, automatic load progression, rest timers and technique videos by Jeff Nippard. It is not part of the nutrition subscription. Each app can be bought on its own, or both together with an annual bundle.

In the US, Workouts costs the same as the nutrition app and the bundle is $89.99 a year. In Europe, the App Store lists Workouts slightly higher than the nutrition app:

On the App Store listings for France, Spain, Germany, Norway and the US, MacroFactor lists two languages only: English and Japanese. Menus, weekly check-ins and in-app explanations are therefore in English for anyone in Europe.

A German version is on the way. In its 2026 annual report, updated on September 30, the publisher writes that MacroFactor will “soon” be available in German, bringing the app to three languages. French, Spanish and Norwegian have not been announced.

Most calorie counters set your target once, using a formula that estimates your basal metabolic rate and activity. MacroFactor starts from that estimate, then corrects it with your own numbers. The principle, explained on its website, is energy balance: calories in minus the change in stored energy equals calories out. All you need to do is log what you eat and weigh yourself regularly.

Every week, a check-in recalculates your expenditure and adjusts your calorie and macro targets to the pace you chose, whether you want to lose, maintain or gain weight. The publisher stresses two points: the algorithm works just as well if you missed your targets, and the app shows no red numbers or warnings when you go over. Another deliberate choice: it does not use smartwatch or activity tracker data, which the publisher considers unreliable for estimating expenditure.

MacroFactor does not handle payments itself: the trial and the subscription go through the App Store or Google Play, and that is where you cancel. The App Store listing states that the subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Another trap: deleting your account in the app erases your data but does not cancel your subscription.

Ratings are high everywhere, with far more reviews in the US than in Europe. The publisher reports more than 600,000 users in September 2026, up from 185,000 two years earlier.
