Custom goals with macros that recalculate automatically
Goals change — a cut becomes a maintenance phase, a maintenance phase becomes a bulk. Theron recalculates your calorie and macro targets automatically whenever you update your goal, instead of leaving you to redo the math by hand.
Set your goals freeWhy automatic recalculation matters
Manually recalculating macros every time your weight, activity, or goal shifts is exactly the kind of friction that causes people to just stop adjusting — and keep tracking against stale numbers. Automatic recalculation keeps your targets accurate without extra effort.
