Best macro tracker for weight loss
For sustained fat loss, the single biggest predictor of success in published trials is logging adherence — not the precise calorie count.
How we judged this category
Welling wins because friction kills adherence. A 720 ms photo log beats a 90-second manual entry, and the adaptive coach keeps you out of the under-eating trap that causes most plateaus.

Other categories you may want
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.
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.
Keto & low-carb
On keto, the only number that decides whether you stay in ketosis is net carbs — and most apps still surface gross carbs by default.
Intermittent fasting
IF apps cluster around fasting timers. The real question is whether the tracker pairs fasting windows with adequate protein and electrolytes when you do eat.
