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
• Detailed breakdowns of micronutrients, macros, and more
• Period tracker, habit tracker, unique data insights and visualization, integrations, dark mode, and more

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.

I had used Lose It! for years and had great success losing weight, but I finally wanted to commit to a bulk so I was willing to spend a little money to do it with a solid calorie tracker. In only a week I've been blown away by the adaptability of this app and the incredible versatility! Bulking, cutting, or maintaining, Macrofactor does it all and adapts as long as you're logging! Worth every penny.

I've been using this app for about 5 days now. I think the app is very useful if you're just tracking macros. I've been going to the gym these past couple of days, and my calorie intake doesn't change. I have to go to lifesum my other macro app to track my calories from consumption to burnt from physical activities. Overall, I would give this app a 5 star just for the diet aspect, but I think it's missing a vital part, so for my needs, it gets a 3.

With MacroFactor, you need to give the app a full 6-7 days of nutrition data to start making your calculations for you. We know it can be tough not to see numbers change immediately, but if you trust the process, the app will reliably get you to your accurate TDEE.

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!
