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.

This is a very good app if you are focused on a weight goal. I've tried several different apps this one is the best. If you want results you need to be honest with yourself and consistent. This app sort of forces that because the algorithm makes adjustments. Dishonesty will lead to caloric restrictions. I love it. Unfortunately unforseen costs made it hard to justify keeping the subscription. I'm not training for anything specific so really I just need to put the fork down.

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.

Really love the app, cannot think of one thing to suggest, and it is regularly updated. The only reason for three starts is that when I add a widget, I cannot see a confirm button to keep my settings. The 2x1 Nutrient focus widget for example I have to have the MacroFactor Theme with search and calories, I cannot change these. Using a Google Pixel 9 Pro Android 16.
