Static macro targets stop working when bodyweight changes. Here are the apps that adjust macros based on observed trends — fast, accurate, free.
The targets that worked at the start of a cut stop working partway through, because TDEE drops with bodyweight. Apps that don't recalibrate targets leave their macro math systematically wrong over time.
