DIET SMARTER

Using a best-in-class expenditure estimate, MacroFactor’s nutrition coach algorithm adapts to changes in your metabolism so you never plateau.

• The unique energy expenditure calculation detects changes in your metabolism
• Smart algorithms personalize your calorie and macro intake targets, just like a nutrition coach would
• Weekly check-ins keep you on track toward your goals

The result? You better understand your body’s needs and can successfully reach and sustain your goals without stress.

THE BEST MACRO TRACKER TOOLS

• The fastest macro tracker on the market with tools like barcode scan and custom foods
• Verified food database, so you can trust the accuracy of the foods you log
• Custom macro programs and weekly check-ins based on your goals and preferences

AN EMPOWERING, SUSTAINABLE APPROACH

MacroFactor’s robust nutrition coach algorithm will make appropriate adjustments to your calorie and macro targets based on what you log, regardless of how close you came to hitting your targets from the previous week. The algorithms don’t function any worse if you deviate from your macro targets.

This means that unlike other nutrition coach apps, you don’t have to eat like a robot or perfectly adhere to your macro targets in order to get your weekly coaching check-in and an appropriate calorie adjustment.

You’ll never see warnings, red numbers, or shaming when you go over your calorie or macro targets, unlike in other macro tracker apps.

Instead, MacroFactor’s macro tracker and nutrition coach aim to empower you with the guidance and tools you need to reach your goals without stress or rigidity.

The AI is pretty amazing at recognizing food and and ingredients. Its even astonishingly accurate sometimes, calorie wise. The problem is its astonishingly inaccurate sometimes too. For anyone serious about counting, this AI won't cut it. If your not here for the AI, I dont know how you justify the monthly cost when you can do the same thing for free elsewhere. If you buy the year up front, its high but more reasonable. I just dont imagine most people track for a full year at a time.

It's a killer app. I've already lost 5 pounds on less than a months time. Very intuitive and by far the best macro tracker, even compared to MyFitnessPal. The AI to type in things makes life convenient too. Suggestion 8/28/24: It would be great if Ai describe can do multiple items at once. Example: 4 oz of chicken breast , 100 G of rice , 100 G of broccoli. " Hopefully shouldn't be too difficult to make that update!

Thanks, Jason! Glad you're enjoying it! Also...I think you should just be able to say "20 blueberries" or "80 grams of old fashioned oats" into AI describe and get appropriate entries back. Give it a shot!

Top notch. I love the adjustment of calories depending on your weight. I was going to rate it four stars because it can be hard to find some food items in the database (not as good as some other nutrition programs), but not worth a star off, as long as I keep losing weight and getting in better shape, keeping it five stars. Going to share with family. EDIT: Macrofactor checks Play Integrity API. None of the apps I have do this. Just say no to apps against privacy. Not a fan of my data analyzed.
