Our verdict
A fit for people who already log weight and meals consistently and want the app to estimate expenditure and adjust targets weekly. The trade-offs are no free tier beyond a 7-day trial and results that depend on how complete your logging is.
Best for: Serious trainees tracking macros to cut or build muscle.
Skip it if: Anyone who wants a free calorie counter or logs only occasionally.
Pros
- Calorie and macro targets adjust from your food and weight logs, with a daily expenditure (TDEE) estimate.
- Several logging methods: AI photo, typed or spoken description, barcode and nutrition-label scan; the developer cites more than 1.36 million verified foods.
- Rated 4.8/5 on the US App Store (over 23,900 ratings) and US Google Play (about 17,700 reviews).
Cons
- No free tier; after the 7-day trial it costs $11.99 per month or $71.99 per year.
- No desktop version yet; the pricing page says one is planned.
All pros and cons · Who is it for?
Pros
- No ads; the privacy notice says data is not sold, and export and account deletion are built into the app.
Cons
- Expenditure is estimated entirely from the data you enter, and no independent check of the algorithm's accuracy was found.
Best for
- People who want the app to propose calorie targets rather than relying on a fixed formula.
Skip it if
- Anyone who wants to log on a computer: only iOS and Android apps exist for now.
Experience & key features
What MacroFactor is
MacroFactor is a nutrition and macro tracking app from Stronger By Science Technologies LLC in the US, released on the App Store on 15 September 2021. The App Store lists iPhone, iPad, Apple Watch and Apple-silicon Mac support, and the pricing page adds an Android version on Google Play. The company's press page says its apps have more than 500,000 users, a self-reported figure.
How it works
The distinguishing piece is the adaptive algorithm: the app estimates energy expenditure from your food and weight logs, then adjusts calorie and macro targets at weekly check-ins. There are three modes: Coached, Collaborative and Manual. Foods can be logged by AI photo, typed or spoken description, barcode and nutrition-label scan. A help article last updated in November 2025 describes two optional add-ons: Step-Informed Updates, which uses step counts to gradually raise or lower estimated expenditure, and Predictive Goal Adjustment, which adjusts targets as soon as you set a new goal. The May 2026 newsletter says AI food logging was upgraded to accept multiple photos combined with text.
Pricing and value
According to the official pricing page there is no free version, only a 7-day trial. Prices are $11.99 per month, $47.99 every 6 months or $71.99 per year. The App Store in-app purchase list also shows $9.99 monthly, $59.99 yearly and an $89.99 yearly bundle that the pricing page does not explain, so this review does not rely on them. Apple or Google bills the subscription, so cancellation and refunds follow their rules.

MacroFactor Workouts and alternatives
The same company also makes MacroFactor Workouts, which the January 2026 newsletter says launched that month. It is a separate app at $11.99 per month or $71.99 per year, with a bundle for existing MacroFactor users. People who want a free tier or a large community food database can look at MyFitnessPal, Lose It!, Cronometer or Cal AI; MacroFactor's strength is the adaptive algorithm, not a free plan. The third-party reviews found were mostly small blogs or written by competitors, so they are not used as primary evidence.

Cancellation & refunds
Per the terms of service (updated 1 Dec 2025), Apple or Google sells and bills the subscription, so cancellation, renewal and refunds follow their rules. The terms state that deleting or uninstalling the app does not entitle you to a refund, and deleting your account in the app does not cancel the subscription.
Privacy
According to the privacy notice (updated 1 Dec 2025), MacroFactor collects email, profile data, body metrics, nutrient intake, workout logs, progress photos and, with permission, data from Apple Health, Fitbit, Google Fit and Health Connect. The company says it does not sell personal data or share it for cross-context behavioral advertising; data goes only to service providers such as Google (Firebase), RevenueCat and Gleap. Data export and account deletion are available in the app under More > Data Management. The AI section is unclear: the notice says Google provides AI services for some features and that no other AI provider is used, yet it also mentions an optional GPT-4 model for the knowledge base without naming the provider. The App Store privacy label lists health data, photos, email and purchase history as linked to the user, with email and purchase history also used for the developer's own advertising or marketing.

Why this score
Many quick logging routes (photo, speech, barcode), but concepts such as expenditure and weekly check-ins take some learning. Based on feature descriptions and store ratings, not hands-on use.
Why this score
Adaptive targets, Weight Trend, micronutrient tracking, Coached/Collaborative/Manual modes, recipes, health-platform integrations and two optional expenditure modifiers. No desktop version yet.
Why this score
The $71.99 yearly plan (about $5.99 per month) is reasonable for a specialist tracker, but there is no free tier and the $11.99 monthly plan is on the high side.
Why this score
4.8/5 on both stores and frequent releases (5.8.11 reached the App Store on 5 Nov 2026). No independent accuracy test of the algorithm was found, so the score stays moderate.
Why this score
Help center, email and in-app support, plus a public feedback roadmap. No live chat or phone, and no independent source on response times was found, so it sits level with peers that offer email-only support.
Why this score
No-sale commitment, in-app export and account deletion, a dedicated health data notice, and no data listed as used to track you on the App Store label. Deductions: email and purchase history are used for marketing, and the AI vendor section is unclear.
