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.

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!

Works great and makes tracking more convenient imo. Easy to add an item they don't have using the new barcode feature and putting the nutrition label into the cameras view. I somehow double subscribed under the same email and same card, so careful when setting up your subscription. I realized I was getting double charged after a couple months. Most likely human error on my side, but it is kind of weird to me it was even possible.

I've had MacroFactor about two weeks now, and, coming from someone who uses Cronometer, it has its pros and cons. Obviously, paying for Macrofactor is a huge con, especially if you, like myself, are against AI and are avoiding it on the app. Additionally, when quick adding items, sometimes they just disappear. I will put in the items from a custom order I had and the next day they are no longer logged. Otherwise, love the check ins and changing outlooks and suggestions.
