About this app

MacroFactor is a macro tracker, calorie counter, and nutrition coach app that helps you reach your diet goals to lose weight, gain muscle, or maintain with empowering, sustainable results, by combining innovative coaching algorithms with proven nutrition and behavioral science.

KEY CAPABILITIES

• Adaptive nutrition coach: smart algorithms personalize your calorie and macro intake targets, just like a nutrition coach would, and weekly check-ins keep you on track

• Best-in-class expenditure estimate (TDEE): calculates how many calories you actually burn from your own logs and weight data, so your plan fits your body instead of a generic formula

• Fastest macro tracker on the market: log food by AI photo, meal description, speech-to-text, barcode scanner, or nutrition label scanner, so logging takes seconds

• Verified food database: more than 1.36 million entries, so you can trust the calorie and macro information of the food you log

• Food and meal tracker: covers macros and micronutrients with detailed breakdowns for every meal and day, so you see exactly what you eat

• Weight Trend: cuts through the noise of daily weight fluctuations, so you see your real progress

• Flexible plans: choose Coached, Collaborative, or Manual mode with balanced, low-carb, keto, or carb-focused diets and different macros on different days, so your plan fits your health and fitness goal

• Extra tools in one app: period tracker, habit tracker, data insights and visualization, integrations, and dark mode.

HOW IT WORKS

1. Set your goal (lose, maintain, or gain) and choose your rate of weight change to set your calorie deficit or surplus.

2. Log your meals in the food log and weigh in with the weight tracker as usual.

3. Each week, MacroFactor compares your calorie and macro intake with your weight trend to calculate your true energy expenditure (TDEE) and detect changes in your metabolism.

4. It then adjusts your calorie, protein, and macro targets for the week ahead, so your diet plan keeps working and you avoid a plateau.

FAQ

• How does MacroFactor set my calorie target?

It estimates your energy expenditure from your food logs and weight trend, then adjusts your targets at each weekly check-in.

• What if I go over my targets or skip logging?

Nothing breaks. The algorithm is adherence neutral, so your check-in and calorie adjustment still work, with no warnings or red numbers.

• Can I set my own macros instead of following the coach?

Yes. Choose Manual mode, and set different macros for different days.

• How can I log food quickly?

Snap a photo with AI food logging, describe your meal, speak it, or scan a barcode or nutrition label.

EDIT II: I was initially concerned that the food database wasn't extensive enough especially for branded foods in my shopping region. However, thanks to the encouraging responses from the developer and my realization that absolute precision isn't what matters most, I've changed my mind. There's always workarounds and I expect that the benefits of the app outweigh minor inconveniences. Shoutout to the person who left the responses!

Thanks! Understood on the database, we’re looking to augment our generic foods with 2 research databases sourced from that area within the next year, and our branded product coverage there is growing rapidly. I hope it feels quite improved next time you try!

Wow, just wow. It's one of the best macro setup and then food tracking app I've tried so far. Ease of use and database on par with Cronometer. I'm thinking of ditching the latter and stick completely with Macrofactor. I've been following Jeff Nippard and his scientific approach for quite a while now and with tremendous results on my side. I'm turning 40 this year and I'm in best shape that I ever was, looking much younger than when I was 30!

This app has so much potential, but doesn't seem quite ready yet. In particular, the fact that expenditure doesn't evolve in real time is a big miss for me who has a really un-regular lifestyle. Many features still lack, but the developers do have a page for ideas and their status so that's amazing! I hope to see better metrics (actual body fat instead of visual?) and integrations in the future that would allow for diet and exercise to co-exist in the app. Keep up the good work 👏
