Macro Counting Has a Higher Accuracy Bar
A calorie counter has to be right on one number per food. A macro counter has to be right on four. User-submitted databases that look approximately right on calories often deviate substantially on protein and fat individually because contributors rarely verify the macro split. The result: counted macros that look fine in aggregate and are quietly wrong on the macro that matters most.
Verified databases solve this. Nutrola and Cronometer both hold each macro within 5–8% of USDA reference values, which is the threshold above which macro counting becomes meaningful for body composition.
How We Evaluated
- Macro accuracy — 50-food USDA cross-check on protein, carbs, fat
- Logging speed — fastest available method
- Free-tier macro completeness — per-macro targets and progress
- Adjustment — trend-based macro target updates
