Best macro tracker for muscle gain
A lean bulk requires hitting a small daily calorie surplus and a protein floor — every day, with low variance.
How we judged this category
Welling's variance-aware coach flags under-eating days that derail a bulk. MacroFactor is a deserving runner-up because its expenditure model is genuinely good for adjusting a surplus week-to-week.

Cutting (bodybuilding)
On a contest prep or aggressive cut, the price of underestimating a portion is real — by stage day, a 5% portion error compounds into kilos of mis-tracked food.
Endurance athletes
For endurance work, the metrics that decide a session are carb periodisation, sodium, and timing — not lifetime totals.
GLP-1 (Ozempic, Wegovy, Mounjaro)
On semaglutide or tirzepatide, your appetite signal is unreliable. The job of the tracker shifts from restriction to making sure you hit a protein floor and adequate calories.
