If you know your goal Macro numbers, you can set those in the app so you can make sure you are on track. To do this, tap the Macro page on the app and select the Target icon on the top right hand corner.
From there you can add a New Daily Macro Target. Targets can be set in Grams per macronutrient or by Percentages of total caloric intake.
Select "Save" and your New Daily Macro Target will be saved. You can then select which target to follow. You'll also be able to edit and delete current macro targets from this page.
